Description

Technical Field

[0001] This invention relates to a communication device, and more particularly to a communication device with high radiation gain. Background Technology

[0002] In the architecture of 5G and 6G non-terrestrial networks (NTNs), satellites and high-altitude platform stations (HAPS) are considered important components to complement traditional terrestrial mobile networks. Geosynchronous Orbit (GSO) satellites maintain fixed positions on Earth, primarily used for broadcasting and fixed communications; Medium Earth Orbit (MEO) satellites, such as GPS and Galileo, are located at intermediate orbital altitudes; and Low Earth Orbit (LEO) satellites, such as SpaceX's Starlink, provide high-speed communication over short distances with lower latency. Furthermore, High Altitude Platform Stations (HAPS), while not satellites, serve as communication platforms flying in the atmosphere, bridging the communication coverage gap between ground-based and satellite systems. A common characteristic of GSO, MEO, LEO satellites, and HAPS is the need to communicate over long distances. Such distances require high-power and high-efficiency amplifiers to ensure signal strength and quality. Solid-state power amplifiers (SSPAs) and traveling wave tube (TWTA) power amplifiers are two types of amplifiers commonly used in these applications. SSPAs are characterized by their solid-state design, while TWTAs are characterized by their high power output. With increasing communication demands, the performance and efficiency of these amplifiers will become a key area of ​​research and development.

[0003] Furthermore, array antennas, also known as phased array antennas, are particularly useful for satellite and HAPS communications due to their ability to electronically scan and form directional beams. These antennas can quickly and flexibly adjust their beam direction to adapt to dynamic communication environments and requirements.

[0004] Therefore, further optimization of high-performance SSPA and TWTA amplifiers, as well as the integration and development of array antennas, will be key components of future non-terrestrial network technology architectures. Summary of the Invention

[0051] Figure 1The diagram illustrates a communication device 100 according to an embodiment of the present invention. For example, the communication device 100 may be a wireless access point, a wearable device, a smartphone, a tablet computer, or a notebook computer. Alternatively, the communication device 100 may be any unit in an Internet of Things (IoT), but is not limited thereto.

[0052] exist Figure 1 In one embodiment, the communication device 100 includes: a first frequency selective surface (FSS) element 110, a second frequency selective surface element 120, a feeding radiation element 130, and a dielectric laser accelerator (DLA) 150. It must be understood that, although not shown in [the original text], [the following text is missing from the original] Figure 1 However, the communication device 100 may also include other components, such as a processor, a power supply module, or a housing.

[0053] The second frequency selection surface element 120 is adjacent to the first frequency selection surface element 110, wherein the first frequency selection surface element 110 and the second frequency selection surface element 120 may be substantially parallel to each other. For example, the first frequency selection surface element 110 may be a partially reflective surface (PRS) element. The second frequency selection surface element 120 may be made of an artificial magnetic conductor (AMC) material. Alternatively, the second frequency selection surface element 120 may be made of a metal material. It should be noted that the terms "adjacent" or "adjacent" in this specification may refer to a distance between the corresponding two elements being less than a predetermined distance (e.g., 10 mm or less), but generally do not include the case where the corresponding two elements are in direct contact with each other (i.e., the aforementioned distance is reduced to 0).

[0054] The feed radiator 130 can be used to generate an electromagnetic signal (SE). Additionally, the feed radiator 130 can be coupled to a signal source (not shown). The shape and type of the feed radiator 130 are not particularly limited in this invention. For example, the feed radiator 130 can be implemented using a slot antenna, a patch antenna, a monopole antenna, a dipole antenna, a loop antenna, or a planar inverted FAntenna (PIFA).

[0055] Electromagnetic signal SE can be propagated using a first frequency selective surface element 110 and a second frequency selective surface element 120. For example, the first frequency selective surface element 110 can be used to partially reflect and partially transmit the electromagnetic signal SE, while the second frequency selective surface element 120 can be used to completely reflect the electromagnetic signal SE. In a preferred embodiment, the first frequency selective surface element 110, the second frequency selective surface element 120, and the feed radiator 130 can collectively form an antenna structure of the communication device 100. Because the electromagnetic signal SE can induce constructive interference near the first frequency selective surface element 110, the antenna structure of the communication device 100 will provide a relatively high radiation gain.

[0056] In some embodiments, the antenna structure of the communication device 100 may cover an operating frequency band between 60 GHz and 500 GHz to support wideband operation in the millimeter wave (mmWave) band. However, the invention is not limited thereto. In other embodiments, the antenna structure of the communication device 100 may also support wideband operation in the terahertz (THz) band.

[0057] To enhance the aforementioned constructive interference, a specific distance DS between the first frequency selection surface element 110 and the second frequency selection surface element 120 can be appropriately designed. For example, if the second frequency selection surface element 120 is made of a synthetic magnetic conductor, the specific distance DS will be approximately equal to 0.25 times the wavelength (λ / 4) of the operating frequency band of the antenna structure of the communication device 100. Alternatively, if the second frequency selection surface element 120 is made of a metallic material, the specific distance DS will be approximately equal to 0.5 times the wavelength (λ / 2) of the operating frequency band of the antenna structure of the communication device 100. In some embodiments, the first frequency selection surface element 110 and the second frequency selection surface element 120 can each be implemented using a multi-layer structure. In some embodiments, the length of each of the first frequency selection surface element 110 and the second frequency selection surface element 120 can be greater than or equal to 10 times the wavelength (10λ) of the operating frequency band of the antenna structure of the communication device 100. In some embodiments, the width of each of the first frequency selection surface element 110 and the second frequency selection surface element 120 may also be greater than or equal to 10 times the wavelength (10λ) of the operating frequency band of the antenna structure of the communication device 100. In addition, the aforementioned specific distance DS may also be approximately equal to 0.1 times the wavelength (λ / 10) of the operating frequency band of the antenna structure of the communication device 100.

[0058] In some embodiments, a dielectric laser accelerator 150 is disposed between a first frequency selective surface element 110 and a second frequency selective surface element 120. The dielectric laser accelerator 150 can be used to emit an electron beam 160, wherein the emission direction of the electron beam 160 may be substantially parallel to both the first and second frequency selective surface elements 110, but is not limited thereto. The electron beam 160 may be present between the first and second frequency selective surface elements 110 and 120, and the electron beam 160 can interact with the aforementioned electromagnetic signal SE. Generally, a coupling effect occurs between the electron beam 160 and the electromagnetic signal SE, thereby enhancing the radiation energy of the electromagnetic signal SE. In this design, since some of the energy of the electron beam 160 is transferred to the electromagnetic signal SE, offsetting the propagation attenuation of the electromagnetic signal SE, the radiation gain of the antenna structure of the communication device 100 can be significantly improved. It is important to note that the proposed dielectric laser accelerator 150 has a smaller overall size compared to a conventional electron gun. Furthermore, since the proposed dielectric laser accelerator 150 can be easily integrated with the antenna structure of the communication device 100 onto a single silicon substrate (not shown), the overall manufacturing cost of the communication device 100 of the present invention can be significantly reduced.

[0059] In some embodiments, the communication device 100 further includes a multi-beam aperture board (not shown) disposed adjacent to the dielectric laser accelerator 150. The aforementioned multi-beam aperture board can be used to decompose the electron beam 160 into multiple small beams, wherein these small beams may have different emission directions. For example, the aforementioned multi-beam aperture board may have multiple openings, wherein the diameter of each opening may be less than or equal to 100 μm, but is not limited thereto.

It should be noted that the plurality of dielectric laser accelerators 350-1, 350-2, ..., 350-M are arranged along a virtual loop 380, wherein the multiple electron beams 360-1, 260-2, ..., 360-M can have different emission directions. For example, the aforementioned loop 380 can be approximately circular, but is not limited to this. According to actual measurement results, the application of more electron beams helps to further enhance the radiation gain of the antenna structure of the communication device 300. Figure 3The remaining features of the communication device 300 are the same as Figure 1 The communication device 100 is similar, so both embodiments can achieve similar operational effects.
