[0099] The present disclosure will now be described in more detail with reference to the following examples. It should be noted that the following description of some of the embodiments presented herein is for illustration and description purposes only. It is not intended to be exhaustive or limited to the precise form disclosed.

[0100] Human visual information comprises approximately 80% of the total information obtained, making vision one of the main channels through which individuals perceive and collect information from the outside world. In the digital age, display devices are used as devices for visually perceiving the world, including a large number of devices such as phones, cameras, computers, televisions, and control panels, which have become an integral part of daily life.

[0101] As technology advances, the integration of display devices continues to evolve to meet various needs. The integration of millimeter wave antennas into these devices enables wireless transmission and reception of communication signals. The shape and length of these antennas can be adjusted to adapt to the specific frequency band of electromagnetic waves utilized. Therefore, different types of antennas may be necessary to meet various frequency bands. Therefore, recent research is devoted to the study of display panels that include conductive patterns to facilitate the implementation of antennas.

[0102] In the context of the millimeter wave bands used in 5G technology, the size of the antenna is significantly reduced to the millimeter level. By applying a quarter-wavelength calculation, the size of the terminal antenna is usually in the range of about 2.5mm. Due to the limited diffraction ability of millimeter waves, they are usually used in an array configuration to improve performance. Antenna-in-Package (AiP) technology is consistent with the growing trend of increasing integration in silicon-based semiconductor processes. AiP technology strikes a balance between antenna performance, cost and physical size, reflecting the main development direction of millimeter wave terminals. Other types of millimeter wave antennas are currently being explored as potential millimeter wave solutions, such as antennas-in-antenna-in-package (AiP), antenna on display (AoD) and antenna in metalframe (AiME). Among these options, AoD stands out due to its significant advantages. It not only maximizes the utilization of available space compared to the front frame, back-end module and back shell, but also benefits from a relatively simplified electromagnetic environment and minimizes sensitivity to interference from other signals.

In some embodiments, the display device includes a buffer layer BUF; a first touch layer ML1, which is located on the buffer layer BUF; a touch insulating layer TI, which is located on a side of the first touch layer ML1 away from the buffer layer BUF; a second touch layer ML2, which is located on a side of the touch insulating layer TI away from the buffer layer BUF; an outer coating OC, which is located on a side of the second touch layer ML2 away from the touch insulating layer TI; a dielectric layer DL, which is located on a side of the outer coating OC away from the touch insulating layer TI; and a radiation plate RP of the antenna, which is located on a side of the dielectric layer DL away from the outer coating. The radiation plate RP is configured to send or receive radio frequency signals. The dielectric layer DL is configured to provide electrical insulation and manage the distribution of the electric field.

[0114] In some embodiments, Figure 6 The buffer layer BUF shown is Figure 3 The buffer layer shown, for example, the display device further includes a display module located below the buffer layer BUF.

[0115] In some embodiments, reference Figures 4 to 6 The antenna ATN includes a feed line FL, a slot ST on the feed line FL, a dielectric layer DL on a side of the slot ST away from the feed line FL, and a radiation plate RP on a side of the dielectric layer DL away from the slot ST.

[0116] In some embodiments, the display module DM is a light-emitting diode display module, such as an organic light-emitting diode display module. With the continuous advancement of screen manufacturing technology, the design of the organic light-emitting diode display module is intended to achieve a higher screen-to-body ratio and enhanced integration of electronic components. This development towards improved integration has promoted the emergence of innovative technologies such as under-display fingerprint recognition and under-display camera systems. These technologies use ambient light to capture the image of the lower layer through the screen layer. Therefore, highly transparent film materials must be used in organic light-emitting diode display modules. When compared with traditional polarizing films, the application of color filters on encapsulation (COE) shows superior advantages in utilizing the full display (FDC) setting of the camera, thereby enhancing the overall performance and user experience. After completing the traditional encapsulation, non-polarizing film technology is adopted in the organic light-emitting diode display module by applying an additional color filter layer. Each pixel is associated with a corresponding color filter, and the gaps between the pixels are separated by a black matrix. The color filter layer effectively alleviates problems related to reflection and transparency. In the case of incident light from the external environment, the undesirable part is absorbed by the black matrix area, while the transmitted part passes through the color film. The transmitted light undergoes reflection at the pixel level and is subsequently intercepted by the black matrix area, or absorbed by other color filter areas. For the main RGB wavelengths, the color filter layer exhibits significantly higher transmittance, in the range of 70% to 90%. This level of transparency exceeds that of the polarizing film by a considerable margin.

[0117] Figure 7 is a cross-sectional view of a portion of a display device according to some embodiments of the present disclosure. Figure 7 FIG. 4 shows a packaged color film display device in some embodiments of the present disclosure.

The self-closing form SCF conforms to surface irregularities. The back film BF, as a protective component, is firmly adhered to the base substrate of the display panel to provide structural support, shielding and overall integrity to the heat dissipation structure HDS.

[0122] In some embodiments, antennas, such as millimeter wave antennas, can be integrated into the display devices discussed in the present disclosure. The inventors of the present disclosure have discovered that due to the presence of a large number of metal traces in the display module, the display module exhibits a strong blocking effect on electromagnetic waves, effectively behaving as a metal layer. The present display device overcomes this problem and surprisingly and unexpectedly achieves wave transmission through the display module.

[0123] In some embodiments, to facilitate millimeter wave communication, the antenna (e.g., millimeter wave antenna) adopts a coupled feeding method, in which the radiation plate is located above the display module and the feed line is located below the display module. In some embodiments, the radiation plate is located on the side of the touch structure away from the display module, such as Figures 4 to 6The inventors of the present disclosure have found that by placing the radiation plate on the side of the touch structure away from the display module, the antenna needs to have the same or higher transparency as the touch layer to avoid affecting the display performance. Therefore, in some embodiments, the antenna is made of a metal mesh material, which has good conductivity and relatively low radiation loss.

Optionally, the orthographic projection of the radiation plate RP on the substrate BS does not substantially overlap with the orthographic projection of a corresponding first touch electrode among the plurality of first touch electrodes TE1 on the substrate BS (for example, at least 80% non-overlapping, at least 85% non-overlapping, at least 90% non-overlapping, at least 95% non-overlapping, at least 99% non-overlapping, or no overlapping), and does not substantially overlap with the orthographic projection of a corresponding second touch electrode among the plurality of second touch electrodes TE2 on the substrate BS (for example, at least 80% non-overlapping, at least 85% non-overlapping, at least 90% non-overlapping, at least 95% non-overlapping, at least 99% non-overlapping, or no overlapping).

[0137] In some embodiments, the radiation plate RP is a metal mesh radiation plate.

[0138] The inventors of the present disclosure have found that a display module including various substrates, light-emitting layers, and encapsulation layers includes a large number of metal traces, which results in a strong electromagnetic wave blocking effect, effectively making the display module equivalent to a metal layer.

[0139] Therefore, the present disclosure provides, in particular, a display device that substantially eliminates one or more problems caused by the limitations and disadvantages of the prior art.

[0140] Fig.14 is a plan view of a display device according to some embodiments of the present disclosure. Fig.15 is a plan view of a display device according to some embodiments of the present disclosure. Fig.16A is a cross-sectional view of a portion of a display device according to some embodiments of the present disclosure. Figures 14 to 16A In some embodiments, the display device includes a peripheral area PA and a display area DA. In some embodiments, the display area DA of the display device includes a first display sub-area DA1 and a second display sub-area DA2. Optionally, the first display sub-area DA1 and the second display sub-area DA2 do not overlap with each other. Optionally, the first display sub-area DA1 and the second display sub-area DA2 are continuous display areas, so that the image can be displayed uninterruptedly in the entire first display sub-area DA1 and the second display sub-area DA2. The entire image can be displayed in the display device. In some embodiments, the radiation plate RP of the antenna ATN is located on the light emitting side LES of the display module DM, and the feed line FL and / or the integrated circuit IC can be located on the back side BBS of the display module DM.

[0141] In some embodiments, the transmittance of the second display sub-region DA2 is lower than that of the first display sub-region DA1. In some embodiments, the area occupied by the opaque component of the second display sub-region DA2 is lower than that of the first display sub-region DA1.

[0142] In some embodiments, the sub-pixel distribution density of the second display sub-area DA2 is lower than the sub-pixel distribution density of the first display sub-area DA1. As used herein, the term "sub-pixel distribution density" refers to the number of sub-pixels contained within a given area of ​​a display device. As used herein, a sub-pixel refers to the smallest light-emitting unit in a display device.

[0143] In some embodiments, the display device further includes an antenna area ATA having an antenna ATN. In some embodiments, the antenna area ATA is at least partially located in the second display area DA2. Optionally, the antenna area ATA is completely located in the second display area DA2.

[0144] See also Fig.14 , in some embodiments, the second display sub-area DA2 is located at least one of the second side S2 or the fourth side S4 of the first display sub-area DA1. Optionally, the second display sub-area DA2 does not exist in at least one of the first side S1 or the third side S3 of the first display sub-area DA1. Optionally, the first side S1 and the third side S3 are opposite to each other. Optionally, the second side S2 and the fourth side S4 are opposite to each other. In one example, the antenna ATN is in a portion of the second display sub-area DA2 located at the second side S2 of the first display sub-area DA1. In another example, the antenna ATN is in a portion of the second display sub-area DA2 located at the fourth side S4 of the first display sub-area DA1.

[0145] See also Fig.15, in some embodiments, the second display sub-area DA2 is located on at least one of the first side S1 or the third side S3 of the first display sub-area DA1. Optionally, the second display sub-area DA2 does not exist on at least one of the second side S2 or the fourth side S4 of the first display sub-area DA1. Optionally, the first side S1 and the third side S3 are opposite to each other. Optionally, the second side S2 and the fourth side S4 are opposite to each other. In one example, the antenna ATN is in a portion of the second display sub-area DA2 located on the first side S1 of the first display sub-area DA1. In another example, the antenna ATN is in a portion of the second display sub-area DA2 located on the third side S3 of the first display sub-area DA1.

[0146] In the display module DM, the sub-pixel distribution density in the second display sub-area DA2 is determined based on the components of the second display sub-area DA2 and the display requirements. For example, the second display sub-area DA2 may include an under-display camera, an under-display fingerprint sensor, an antenna, etc. When the under-display antenna is placed in the second display sub-area DA2, the best display effect can be achieved when the sub-pixel distribution density is relatively low because it can affect the antenna radiation. On the contrary, when the sub-pixel distribution density is too low, although better radiation performance can be achieved, it may affect the display quality.

[0147] In some embodiments, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is less than 1:1, for example, less than 1:1.5, less than 1:2.0, less than 1:2.5, less than 1:3.0, less than 1:3.5, less than 1:4.0, less than 1:4.5, less than 1:5.0, less than 1:5.5, less than 1:6.0, less than 1:6.5, less than 1:7.0, less than 1:7.5, less than 1:8.0, less than 1:8.5, less than 1:9.0, less than 1:9.5 or less than 1:10.0. In some embodiments, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is greater than 1:100, for example, greater than 1:95, greater than 1:90, greater than 1:85, greater than 1:80, greater than 1:75, greater than 1:70, greater than 1:65, greater than 1:60, greater than 1:55, greater than 1:50, greater than 1:45, greater than 1:40, greater than 1:35, greater than 1:30, greater than 1:25, greater than 1:20, greater than 1:15, greater than 1:10 or greater than 1:5.

[0148] In one example, the ratio of the sub-pixel distribution density of the second display sub-area DA2 to the sub-pixel distribution density of the first display sub-area DA1 is not less than 1:4. In another example, in the case where the display module DM has a higher resolution, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 can be lower than 1:4. The second display sub-area DA2 is used as a low-density sub-pixel area and is mainly located around the first display sub-area DA1, such as near the left and right boundaries or the upper and lower boundaries. This arrangement allows the antenna to be closer to the edge to minimize the path loss in the feeder FL. In addition, reducing the display resolution in the peripheral area has minimal visual impact on the entire display, thereby reducing display changes caused by different pixel densities.

[0149] Fig. 16B is a cross-sectional view of a portion of a display device according to some embodiments of the present disclosure. Fig. 16B In some embodiments, the orthographic projection of the radiation plate RP on the base substrate does not overlap with the orthographic projection of the sub-pixel sp in the second display sub-area DA2 on the base substrate.

[0150] Fig. 16C is a cross-sectional view of a portion of a display device according to some embodiments of the present disclosure. Fig. 16C In some embodiments, the orthographic projection of the radiation plate RP on the base substrate does not overlap with the orthographic projection of the sub-pixel sp in the second display sub-area DA2 on the base substrate. Optionally, the orthographic projection of the radiation plate RP on the base substrate at least partially overlaps with the orthographic projection of the dummy sub-pixel dsp in the second display sub-area DA2 on the base substrate.

[0151] Fig.17 1 shows the sub-pixel distribution density in the first display sub-area and the second display sub-area of ​​the display device according to some embodiments of the present disclosure. Fig.17 , the sub-pixel distribution density in the second display sub-area DA2 is lower than the sub-pixel distribution density in the first display sub-area DA1. Fig.17 In one example shown, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is in the range of 1:2.5 to 1:3.5. In a specific example, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is 1:3.

[0152] Reference Fig.17In one example, a pixel in the display module includes four sub-pixels, including a first sub-pixel sp1, a second sub-pixel sp2, a third sub-pixel sp3, and a fourth sub-pixel sp4. In one example, the first sub-pixel sp1 is a sub-pixel of a first color, the second sub-pixel sp2 is a sub-pixel of a second color, and the third sub-pixel sp3 and the fourth sub-pixel sp4 are sub-pixels of a third color. In another example, the first sub-pixel sp1 is a red sub-pixel, the second sub-pixel sp2 is a blue sub-pixel, and the third sub-pixel sp3 and the fourth sub-pixel sp4 are green sub-pixels.

[0153] In one example, the red sub-pixels and the green sub-pixels are arranged in a staggered and offset manner, while the blue sub-pixels and the green sub-pixels are arranged in the same row but not in the same column. In the same pixel, the two green sub-pixels are positioned adjacent to each other along the column direction and are symmetrical about the row direction, and the two green sub-pixels in the same pixel are mirror images of each other. The individual luminous area of ​​the green sub-pixel is smaller than the individual luminous area of ​​the red sub-pixel, and the individual luminous area of ​​the green sub-pixel is also smaller than the individual luminous area of ​​the blue sub-pixel. This is because the green sub-pixel has a higher luminous efficiency than the sub-pixels of other colors.

[0154] In some embodiments, the number of red sub-pixels is the same as the number of blue sub-pixels, and the number of green sub-pixels is twice the number of red sub-pixels and twice the number of blue sub-pixels. The red sub-pixels have substantially the same area as the blue sub-pixels. The sub-pixels can take various suitable shapes. The sub-pixels can have regular or irregular shapes.

[0155] Since the sub-pixel distribution density in the second display sub-area DA2 is lower than that in the first display sub-area DA1, waves are allowed to transmit through the second display sub-area DA2, so that electromagnetic waves can pass through the display module.

[0156] Fig.18 1 shows the sub-pixel distribution density in the first display sub-area and the second display sub-area of ​​the display device according to some embodiments of the present disclosure. Fig.18 In some embodiments, the second display sub-area DA2 further includes a plurality of dummy sub-pixels, including a first dummy sub-pixel dsp1, a second dummy sub-pixel dsp2, a third dummy sub-pixel dsp3, and a fourth dummy sub-pixel dsp4. The first dummy sub-pixel dsp1 corresponds to the first sub-pixel sp1 in the first display sub-area DA1, the second dummy sub-pixel dsp2 corresponds to the second sub-pixel sp2 in the first display sub-area DA1, the third dummy sub-pixel dsp3 corresponds to the third sub-pixel sp3 in the first display sub-area DA1, and the fourth dummy sub-pixel dsp4 corresponds to the fourth sub-pixel sp4 in the first display sub-area DA1.

[0157] As used herein, the term "dummy" refers to a sub-pixel having the same or similar structure as an active sub-pixel, but the structure is only used for a configuration that exists as a pattern and does not actually perform a function in the display device. Therefore, an electrical signal may not be applied to the "dummy" sub-pixel, or even if an electrical signal is applied to the "dummy" sub-pixel, the "dummy" sub-pixel may not perform an electrically equivalent function.

[0158] In some embodiments, there is no functional layer in the dummy sub-pixel compared to the sub-pixel. In one example, there is no light-emitting layer in the dummy sub-pixel compared to the sub-pixel. In another example, there is no anode in the dummy sub-pixel compared to the sub-pixel. In another example, there is no transistor in the dummy sub-pixel in the pixel drive circuit of the dummy sub-pixel compared to the sub-pixel. In another example, there is no capacitor in the dummy sub-pixel in the pixel drive circuit of the dummy sub-pixel compared to the sub-pixel. The absence of layers or components in the dummy sub-pixel helps to reduce the effective metal area and reduce interference with electromagnetic waves. By setting the dummy sub-pixel, the wave transmission capability in the second display sub-area DA2 can be enhanced.

[0159] Fig.18 The minimum repeating unit MRU in the second display sub-area DA2 is shown. In one example, the minimum repeating unit MRU includes one pixel and two dummy pixels. One pixel in the minimum repeating unit MRU includes a first sub-pixel sp1, a second sub-pixel sp2, a third sub-pixel sp3, and a fourth sub-pixel sp4. Each of the two dummy pixels includes a first dummy sub-pixel dsp1, a second dummy sub-pixel dsp2, a third dummy sub-pixel dsp3, and a fourth dummy sub-pixel dsp4.

Fig.19 , the sub-pixel distribution density in the second display sub-area DA2 is lower than the sub-pixel distribution density in the first display sub-area DA1. Fig.19 In one example shown, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is in the range of 1:3.5 to 1:4.5. In a specific example, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is 1:4.

[0161] Fig.19The minimum repeating unit MRU in the second display sub-area DA2 is shown. In one example, the minimum repeating unit MRU includes one pixel and three dummy pixels. One pixel in the minimum repeating unit MRU includes a first sub-pixel sp1, a second sub-pixel sp2, a third sub-pixel sp3, and a fourth sub-pixel sp4. Each of the three dummy pixels includes a first dummy sub-pixel dsp1, a second dummy sub-pixel dsp2, a third dummy sub-pixel dsp3, and a fourth dummy sub-pixel dsp4.

[0162] Fig. 20 1 shows the sub-pixel distribution density in the first display sub-area and the second display sub-area of ​​the display device according to some embodiments of the present disclosure. Fig. 20 , the sub-pixel distribution density in the second display sub-area DA2 is lower than the sub-pixel distribution density in the first display sub-area DA1. Fig. 20 In one example shown, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is in the range of 1:1.5 to 1:2.5. In a specific example, the ratio of the sub-pixel distribution density in the second display sub-area DA2 to the sub-pixel distribution density in the first display sub-area DA1 is 1:2.

[0163] Fig. 20 The minimum repeating unit MRU in the second display sub-area DA2 is shown. In one example, the minimum repeating unit MRU includes one pixel and one dummy pixel. One pixel in the minimum repeating unit MRU includes a first sub-pixel sp1, a second sub-pixel sp2, a third sub-pixel sp3, and a fourth sub-pixel sp4. One dummy pixel includes a first dummy sub-pixel dsp1, a second dummy sub-pixel dsp2, a third dummy sub-pixel dsp3, and a fourth dummy sub-pixel dsp4.

[0164] Fig.21 1 shows the sub-pixel distribution density in the first display sub-area and the second display sub-area of ​​the display device according to some embodiments of the present disclosure. Fig.21 , the sub-pixel distribution density in the second display sub-area DA2 is lower than the sub-pixel distribution density in the first display sub-area DA1.

[0207] Various methods can be used to feed microstrip antennas, such as gap coupling feeding, coaxial feeding, microstrip line feeding, and coplanar waveguide feeding. Among these methods, gap coupling feeding provides different characteristics. For example, compared with traditional feeding techniques, gap coupling feeding provides a significant increase in antenna impedance bandwidth. The ground plane effectively isolates the radiator from the feed line, minimizing the impact of the feed line on the radiation performance. By placing the dielectric substrates of the radiator and the feed line on opposite sides of the ground plane, different substrates with different dielectric constants can be selected based on specific requirements. Gap coupling feeding provides more adjustable parameters than conventional feeding methods during the design process, thereby facilitating precise port impedance matching. The feed line can be conveniently integrated into the same plane as the antenna, enabling seamless integration with active components. On the other hand, gap coupling feeding involves a multilayer structure, introducing complexity and increasing the manufacturing cost of the antenna. The presence of a coupling gap on the ground plane leads to an increase in reverse radiation. This can be alleviated by incorporating a metal reflector at a quarter wavelength distance from the ground plane, but at the expense of increasing the complexity of the antenna structure.

[0208] The coupling efficiency between a microstrip feedline and a radiator depends primarily on the shape of the coupling gap and its position relative to the radiator. Comparative studies have explored different gap shapes, including "H", "U", and "L" types, where the longitudinal gap controls the coupling strength, while the lateral gap exerts a relatively small effect. The midpoint of the lateral gap exhibits the strongest coupling, and a decrease in coupling efficiency is observed as the distance from the midpoint increases. Rectangular gaps exhibit a more significant drop in coupling efficiency due to their inherent discontinuities. The inventors of the present disclosure have compared various wide gap shapes, such as rectangular, "H", butterfly, and hourglass forms. Among them, the hourglass-shaped gap exhibits the highest coupling efficiency by alleviating the discontinuities present in the "H" and butterfly gap configurations.

[0209] Fig. 27 is a cross-sectional view of a display device according to some embodiments of the present disclosure. Fig. 27 Because the antenna is in the second display sub-area DA2 and the second display sub-area DA2 has a smaller amount of metal traces, the display module DM in the second display sub-area DA2 does not exhibit a strong blocking effect on electromagnetic waves. The present display device allows waves to be transmitted through the second display sub-area DA2, so that electromagnetic waves can pass through the display module DM.

Optionally, the radiation panel RP is a metal mesh radiation panel. Optionally, the radiation panel RP and the auxiliary metal mesh AM are spaced apart from each other by a transition area TA. The inventors of the present disclosure have found that by providing an auxiliary metal mesh AM, any visual effect caused by the presence or absence of a mesh can be prevented. This structure is used for the purpose of reducing the prominence of the radiation panel RP. In the absence of the auxiliary metal mesh AM, the isolated presence of the radiation panel RP will result in a visually abrupt and obvious area. The inventors of the present disclosure have found that by making the transition area TA have an appropriate spacing between the continuous mesh area of ​​the radiation panel RP and the auxiliary metal mesh AM, the visual effect can be further improved. Excessive spacing within the transition area TA will also result in perceptible visual inconsistency.

[0213] In some embodiments, the radiation plate RP comprises a continuous metal mesh network. Fig.30 As shown, the auxiliary metal mesh AM is composed of discontinuous line segments. The existence of the discontinuous line segments of the auxiliary metal mesh AM has the least effect on electromagnetic radiation.

[0235]

[0236]

[0237] As shown in Table 1, Fig.39 , Fig.49 , Fig.57 and Fig.59 The antenna shown in exhibits the deepest resonance (minimum) and the highest gain. Fig.51 and Fig.53 The antenna shown in experiences impedance matching problems, but the frequencies corresponding to the minimum S-parameter value and the maximum gain value are relatively close (with a difference of 0.5 GHz). Fig.47 and Fig.55 The antennas shown in Figure 1 do not perform as well as expected, with a difference of nearly 4 GHz between the frequency of minimum S-parameter value and the frequency of maximum gain value. In addition, their gain is low, indicating a mismatch problem.

[0238] Obviously, Fig.39 The antenna shown, Fig.49 The antenna shown, Fig.57 The antenna and Fig.59 The antennas shown exhibit a resonance depth of up to -20 dB. In terms of port reflections, these models show superior performance. However, Fig.51 The antenna depicted in Fig.53 The antenna depicted in shows a poor resonance effect, with the value hovering around -6dB, which indicates stronger reflections. Fig.47 The antenna described in Fig.55 The antennas described in show moderate resonances, but their radiation gain is relatively low, indicating the presence of spurious resonances. Interestingly, Fig.51 The antenna depicted in Fig.53 The antennas depicted in , although their resonances are not optimal, show relatively consistent radiation gain without significant drop-off.

[0239] By comparison, it is obvious that both the rectangular radiator ( Fig.39 The antenna shown), a rectangular radiating patch with a cross-shaped slot ( Fig.49 The antenna shown) is also a rectangular radiating patch with a bow-tie shaped slot ( Fig.57 The antenna shown), a rectangular radiating patch with a Maltese cross-shaped slot ( Fig.59 The choice of radiator shape produces favorable radiation effects in terms of S parameters and radiation gain. Fig.39 The antenna and Fig.49 The antenna shown is Fig.51 The antenna and Fig.53 When comparing the antennas shown (which share the same radiator shape but different slot configurations), the slot design exerts a considerable influence on the S-parameters while maintaining a negligible effect on the gain. Optimization of the structure between the slot and the feed line can achieve the best performance in terms of S-parameters and gain.
