This invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed based on different viewpoints and applications without departing from the concept of this invention. Furthermore, it should be stated in advance that the accompanying drawings of this invention are for simple illustrative purposes only and are not depictions based on actual dimensions. The following embodiments will further describe the relevant technical content of this invention in detail, but the disclosed content is not intended to limit the scope of protection of this invention. Additionally, the term "or" used herein may, depending on the actual situation, include any combination of any one or more of the associated listed items.
[0020] First Embodiment
[0021] See Figures 1 to 4 As shown, the first embodiment of the present invention provides a coupled antenna module M (or a monopole coupled dual-band antenna), which includes: an antenna carrier substrate 1, a first antenna structure 2, and a second antenna structure 3. It is worth noting that the first antenna structure 2 can be configured to operate within a first antenna operating frequency range, and the second antenna structure 3 can be configured to operate within a second antenna operating frequency range. Furthermore, depending on different requirements, the first antenna operating frequency range can be greater than, equal to, or less than the second antenna operating frequency range.
[0022] Furthermore, in coordination Figure 1 and Figure 2As shown, the antenna carrier substrate 1 may have an upper surface 101, a lower surface 102, a first side surface 103, a second side surface 104, a third side surface 105, and a fourth side surface 106. The upper surface 101 and the lower surface 102 may correspond to each other (or may be arranged oppositely). The first side surface 103 and the second side surface 104 may be connected between the upper surface 101 and the lower surface 102 and correspond to each other (or may be arranged oppositely). The third side surface 105 and the fourth side surface 106 may be connected between the upper surface 101 and the lower surface 102 and correspond to each other (or may be arranged oppositely). For example, the antenna carrier substrate 1 may be rectangular, similar to a rectangular shape, or any possible shape, and the antenna carrier substrate 1 may be any kind of insulating material or high-dielectric material (e.g., ceramic or ceramic-like materials). However, the examples given above are merely one possible embodiment and are not intended to limit the invention.
[0023] Furthermore, in coordination Figure 1 and Figure 2 As shown, the first antenna structure 2 can be disposed on the upper surface 101, lower surface 102, and first side surface 103 of the antenna carrier substrate 1. The first antenna structure 2 may have a first radiating layer 21 (or a first top conductive layer) disposed on the upper surface 101 of the antenna carrier substrate 1, a first extension layer 22 (or a first side conductive layer) disposed on the first side surface 103 of the antenna carrier substrate 1, and a first conductive layer 23 (or a first bottom solder layer) disposed on the lower surface 102 of the antenna carrier substrate 1. Furthermore, the second antenna structure 3 can be disposed on the upper surface 101, lower surface 102, and second side surface 104 of the antenna carrier substrate 1. The second antenna structure 3 may have a second radiating layer 31 (or a second top conductive layer) disposed on the upper surface 101 of the antenna carrier substrate 1, a second extension layer 32 (or a second side conductive layer) disposed on the second side surface 104 of the antenna carrier substrate 1, and a second conductive layer 33 (or a second bottom solder layer) disposed on the lower surface 102 of the antenna carrier substrate 1.
[0024] For example, coordination Figure 1 , Figure 2 and Figure 3As shown, in one feasible embodiment, the first radiating layer 21 of the first antenna structure 2 may have a first base 211, a first extension 212 extending from the first base 211 toward the second side surface 104, and a first bent portion 213 extending from the first extension 212 (e.g., bent at 90 degrees) toward the third side surface 105. The first bent portion 213 of the first radiating layer 21 may be disposed between the second base 311 and the second bent portion 313 of the second radiating layer 31. Furthermore, in conjunction with… Figure 1 , Figure 2 and Figure 4 As shown, in one feasible embodiment, the second radiating layer 31 of the second antenna structure 3 may have a second base 311, a second extension 312 extending from the second base 311 toward the first side surface 103, and a second bent portion 313 extending from the second extension 312 (e.g., bent at 90 degrees) toward the fourth side surface 106. The second bent portion 313 of the second radiating layer 31 may be disposed between the first base 211 and the first bent portion 213 of the first radiating layer 21. It is worth noting that the first antenna structure 2 is not disposed on the third side surface 105 and the fourth side surface 106 of the antenna carrier substrate 1, and the second antenna structure 3 is not disposed on the third side surface 105 and the fourth side surface 106 of the antenna carrier substrate 1, thereby allowing both the third side surface 105 and the fourth side surface 106 of the antenna carrier substrate 1 to have a clear area. However, the examples given above are merely feasible embodiments and are not intended to limit the present invention.
[0025] For example, such as Figure 2 As shown, in one feasible embodiment, for the first radiating layer 21 of the first antenna structure 2, the length of the first base 211 can be greater than, equal to, or less than the length of the first bend 213, the length of the first bend 213 can be greater than, equal to, or less than the length of the first extension 212, the width of the first base 211 can be greater than, equal to, or less than the width of the first bend 213, and the width of the first bend 213 can be greater than, equal to, or less than the width of the first extension 212. Furthermore, as... Figure 2 As shown, in one feasible embodiment, for the second radiating layer 31 of the second antenna structure 3, the length of the second base 311 can be greater than, equal to, or less than the length of the second bend 313, the length of the second bend 313 can be greater than, equal to, or less than the length of the second extension 312, the width of the second base 311 can be greater than, equal to, or less than the width of the second bend 313, and the width of the second bend 313 can be greater than, equal to, or less than the width of the second extension 312. Additionally, as... Figure 2As shown, in one feasible embodiment, the area of the first base 211 of the first radiating layer 21 can be greater than, equal to, or less than the area of the second base 311 of the second radiating layer 31; the area of the first extension 212 of the first radiating layer 21 can be greater than, equal to, or less than the area of the second extension 312 of the second radiating layer 31; and the area of the first bend 213 of the first radiating layer 21 can be greater than, equal to, or less than the area of the second bend 313 of the second radiating layer 31 (that is, depending on different requirements, the area of the first antenna structure 2 can be greater than, equal to, or less than the area of the second antenna structure 3). However, the examples given above are only one feasible embodiment and are not intended to limit the present invention.
[0026] For example, such as Figure 2 As shown, in one feasible embodiment, the upper surface 101 of the antenna carrier substrate 1 may have a continuous meandering region 1010, and the continuous meandering region 1010 may be located between the first antenna structure 2 and the second antenna structure 3. Furthermore, the upper surface 101 of the antenna carrier substrate 1 may have a first separating region 1011 connected to a first end of the continuous meandering region 1010, and the first separating region 1011 may be located between the first extension 212 and the fourth side surface 106 and between the first bend 213 and the fourth side surface 106, thereby separating the first extension 212 and the first bend 213 of the first radiating layer 21 from the fourth side surface 106 by a first predetermined distance. Additionally, the upper surface 101 of the antenna carrier substrate 1 may have a second dividing region 1012 connected to a second end of the continuous meandering region 1010, and the second dividing region 1012 may be located between the second extension 312 and the third side surface 105 and between the second bend 313 and the third side surface 105, thereby separating the second extension 312 and the second bend 313 of the second radiating layer 31 from the third side surface 105 by a second predetermined distance. However, the examples given above are merely one possible embodiment and are not intended to limit the present invention.
[0027] For example, such as Figure 2As shown, in one feasible embodiment, the first base 211 of the first radiating layer 21 may have a first side end 2111 that is flush with the third side surface 105 and a second side end 2112 that is flush with the fourth side surface 106. The second side end 2112 of the first base 211 is not flush with the first extension 212 (they are flush with each other), and the first extension 212 of the first radiating layer 21 is away from the first side end 2111 of the first base 211 and close to the second side end 2112 of the first base 211. Furthermore, the second base 311 of the second radiating layer 31 may have a first side end 3111 that is flush with the fourth side surface 106 and a second side end 3112 that is flush with the third side surface 105. The second side end 3112 of the second base 311 is not flush with the second extension 312 (they are parallel to each other), and the second extension 312 of the second radiating layer 31 is away from the first side end 3111 of the second base 311 and close to the second side end 3112 of the second base 311. However, the examples given above are only one possible embodiment and are not intended to limit the present invention.
[0028] Second Embodiment
[0029] See Figure 5 As shown, the second embodiment of the present invention provides a coupled antenna module M. The main difference between the second embodiment and the first embodiment is that in the second embodiment, the first extension 212 and the first bend 213 of the first radiating layer 21 of the first antenna structure 2, and the second extension 312 and the second bend 313 of the second radiating layer 31 of the second antenna structure 3, can be completely covered by an insulating protective layer 4. It is worth noting that in a feasible embodiment, the first base 211 of the first radiating layer 21 of the first antenna structure 2 and the second base 311 of the second radiating layer 31 of the second antenna structure 3 can be partially covered by the insulating protective layer 4, and the insulating protective layer 4 can have a predetermined identification mark 40 (e.g., product model). For example, the insulating protective layer 4 can be made of silicone, epoxy, or any kind of insulating material. However, the examples given above are only feasible embodiments and are not intended to limit the present invention.
[0030] Third Embodiment
[0031] See Figures 6 to 10As shown, the third embodiment of the present invention provides a coupled antenna module M. The main difference between the third embodiment and the first embodiment is that, in the third embodiment, the coupled antenna module M (e.g., the coupled antenna module M provided in the first embodiment) can be disposed between a first conductive layout layer P1 and a second conductive layout layer P2 on a circuit board P, and one of the first conductive layout layer P1 and the second conductive layout layer P2 can be electrically connected to an antenna signal feed line C (or a coaxial cable). It is worth noting that the circuit board P can have a middle region PR1, a left region PR2 located to the left of the middle region PR1, and a right region PR3 located to the right of the middle region PR1, and the coupled antenna module M can be configured to be disposed in the middle region PR1, the left region PR2, or the right region PR3.
[0032] For example, coordination Figure 6 and Figure 7As shown, when the coupled antenna module M is configured to be located in the middle region PR1 or the left region PR2, the first conductive layout layer P1 of the circuit board P (or the first type of circuit board P) may have a first vertical extension P11 located on the right side of the coupled antenna module M and a first horizontal extension P12 connected to the first vertical extension P11. The second conductive layout layer P2 of the circuit board P may have a second vertical extension P21 located on the left side of the coupled antenna module M and a second horizontal extension P22 connected to the second vertical extension P21. Furthermore, the first vertical extension P11 of the first conductive layout layer P1 may have a first signal feed segment P111 electrically connected to the antenna signal feed line C, a second signal feed segment P112 electrically connected to the first horizontal extension P12, and a first electronic component P113 (e.g., a capacitor or inductor) electrically connected between the first signal feed segment P111 and the second signal feed segment P112. Additionally, the second vertical extension P21 of the second conductive layout layer P2 may have a first vertical extension P211 insulated from (or away from) the antenna signal feed line C, a second vertical extension P212 electrically connected to the second horizontal extension P22, and a second electronic component P213 (e.g., a capacitor or inductor) electrically connected between the first vertical extension P211 and the second vertical extension P212. It is worth noting that the first horizontal extension P12 of the first conductive layout layer P1 may have a first antenna carrier segment P121, and the second horizontal extension P22 of the second conductive layout layer P2 may have a second antenna carrier segment P221. Furthermore, the overall width of the coupled antenna module M is smaller than the width of the first antenna carrier segment P121 of the first horizontal extension P12 and the width of the second antenna carrier segment P221 of the second horizontal extension P22, so that the first antenna structure 2 and the second antenna structure 3 of the coupled antenna module M can be electrically connected to the first antenna carrier segment P121 of the first horizontal extension P12 and the second antenna carrier segment P221 of the second horizontal extension P22, respectively, through conductive materials. However, the examples given above are merely one feasible embodiment and are not intended to limit the present invention.
[0033] For example, coordination Figure 6 and Figure 8As shown, when the coupled antenna module M is configured to be located in the right-side region PR3, the first conductive layout layer P1 of the circuit board P (or the second type of circuit board P) may have a first vertical extension P11 located on the left side of the coupled antenna module M and a first horizontal extension P12 connected to the first vertical extension P11. The second conductive layout layer P2 of the circuit board P may have a second vertical extension P21 located on the right side of the coupled antenna module M and a second horizontal extension P22 connected to the second vertical extension P21. Furthermore, the first vertical extension P11 of the first conductive layout layer P1 may have a first signal feed segment P111 electrically connected to the antenna signal feed line C, a second signal feed segment P112 electrically connected to the first horizontal extension P12, and a first electronic component P113 (e.g., a capacitor or inductor) electrically connected between the first signal feed segment P111 and the second signal feed segment P112. Additionally, the second vertical extension P21 of the second conductive layout layer P2 may have a first vertical extension P211 insulated from (or away from) the antenna signal feed line C, a second vertical extension P212 electrically connected to the second horizontal extension P22, and a second electronic component P213 (e.g., a capacitor or inductor) electrically connected between the first vertical extension P211 and the second vertical extension P212. It is worth noting that the first horizontal extension P12 of the first conductive layout layer P1 may have a first antenna carrier section P121, and the second horizontal extension P22 of the second conductive layout layer P2 may have a second antenna carrier section P221. Furthermore, the overall width of the coupled antenna module M is smaller than the width of the first antenna carrier segment P121 of the first horizontal extension P12 and the width of the second antenna carrier segment P221 of the second horizontal extension P22, so that the first antenna structure 2 and the second antenna structure 3 of the coupled antenna module M can be electrically connected to the first antenna carrier segment P121 of the first horizontal extension P12 and the second antenna carrier segment P221 of the second horizontal extension P22, respectively, through conductive materials. However, the examples given above are merely one possible embodiment and are not intended to limit the present invention.
[0034] For example, coordination Figure 6 and Figure 9As shown, when the coupled antenna module M is configured to be located in the middle region PR1 or the left region PR2, the first conductive layout layer P1 of the circuit board P (or a third type of circuit board P) may have a first vertical extension P11 located on the right side of the coupled antenna module M and a first horizontal extension P12 connected to the first vertical extension P11. The second conductive layout layer P2 of the circuit board P may have a second vertical extension P21 located on the left side of the coupled antenna module M and a second horizontal extension P22 connected to the second vertical extension P21. Furthermore, the first vertical extension P11 of the first conductive layout layer P1 may have a first signal feed segment P111 electrically connected to the antenna signal feed line C, a second signal feed segment P112 electrically connected to the first horizontal extension P12, and a first electronic component P113 (e.g., a capacitor or inductor) electrically connected between the first signal feed segment P111 and the second signal feed segment P112. Additionally, the second vertical extension P21 of the second conductive layout layer P2 may have a first vertical extension P211 insulated from (or away from) the antenna signal feed line C, a second vertical extension P212 electrically connected to the second horizontal extension P22, and a second electronic component P213 (e.g., a capacitor or inductor) electrically connected between the first vertical extension P211 and the second vertical extension P212. It is worth noting that the first horizontal extension P12 of the first conductive layout layer P1 may have a first antenna carrier section P121, a first left-side extension P122 electrically connected to the first antenna carrier section P121 and the second signal feed section P112, a first middle extension P123 located to the right of the first left-side extension P122, a first right-side extension P124 located to the right of the first middle extension P123 and insulated from it, and a third electronic component P125 (e.g., a capacitor or inductor) electrically connected between the first left-side extension P122 and the first middle extension P123. Furthermore, the second horizontal extension P22 of the second conductive layout layer P2 may have a second antenna carrier segment P221, a second right side extension segment P222 electrically connected to the second antenna carrier segment P221, a second middle extension segment P223 electrically connected to the second right side extension segment P222 and the second vertical extension segment P212, a second left side extension segment P224 located to the left of the second middle extension segment P223, and a fourth electronic component P225 (e.g., a capacitor or inductor) electrically connected between the second middle extension segment P223 and the second left side extension segment P224.Furthermore, the overall width of the coupled antenna module M is smaller than the width of the first antenna carrier segment P121 of the first horizontal extension P12 and the width of the second antenna carrier segment P221 of the second horizontal extension P22, so that the first antenna structure 2 and the second antenna structure 3 of the coupled antenna module M can be electrically connected to the first antenna carrier segment P121 of the first horizontal extension P12 and the second antenna carrier segment P221 of the second horizontal extension P22, respectively, through conductive materials. However, the examples given above are merely one possible embodiment and are not intended to limit the present invention.
[0035] For example, coordination Figure 6 and Figure 10As shown, when the coupled antenna module M is configured to be located in the right-side region PR3, the first conductive layout layer P1 of the circuit board P (or the fourth type of circuit board P) may have a first vertical extension P11 located on the left side of the coupled antenna module M and a first horizontal extension P12 connected to the first vertical extension P11. The second conductive layout layer P2 of the circuit board P may have a second vertical extension P21 located on the right side of the coupled antenna module M and a second horizontal extension P22 connected to the second vertical extension P21. Furthermore, the first vertical extension P11 of the first conductive layout layer P1 may have a first signal feed segment P111 electrically connected to the antenna signal feed line C, a second signal feed segment P112 electrically connected to the first horizontal extension P12, and a first electronic component P113 (e.g., a capacitor or inductor) electrically connected between the first signal feed segment P111 and the second signal feed segment P112.
