“…To design Low-THz high gain antenna, some methods have been demonstrated. Up to date, many papers have been published on this topic, such as horn antennas [50]- [51], traditional planar antenna arrays [52]- [56], transmitarrays (TA) or lens antennas [57]- [63], reflect-arrays (RA) [64]- [70], and resonant cavity antennas (RCA) [71]- [83].…”

100 GHz-1.0 THz) technology is expected to provide unprecedented data rates in future generations of wireless system such as the 6 th generation (6G) mobile communication system. Increasing the carrier frequencies from millimeter wave to THz is a potential solution to guarantee the transmission rate and channel capacity. Due to the large transmission loss of Low-THz wave in free space, it is particularly urgent to design high-gain antennas to compensate the additional path loss, and to overcome the power limitation of Low-THz source. Recently, with the continuous updating and progress of additive manufacturing (AM) and 3D printing (3DP) technology, antennas with complicated structures can now be easily manufactured with high precision and low cost. In the first part, this paper demonstrates different approaches of recent development on wideband and high gain sub-millimeter-wave and Low-THz antennas as well as their fabrication technologies. In addition, the performances of the state-of-the-art wideband and high-gain antennas are presented. A comparison among these reported antennas is summarized and discussed. In the second part, one case study of a broadband high-gain antenna at 300 GHz is introduced, which is an all-metal model based on the Fabry-Perot cavity (FPC) theory. The proposed FPC antenna is very suitable for manufacturing using AM technology, which provides a low-cost, reliable solution for emerging THz applications.INDEX TERMS Antennas, low-terahertz, additive manufacturing (AM), high gain, Fabry-Perot cavity (FPC), low-cost, three-dimensional printing (3DP).

“…Some advancements of LWA are mentioned in [31]. Resonant Cavity structure based LWA are also most preferable for significantly enhance gain of a single antenna element [32][33][34][35][36][37]. The 2-D leaky wave antenna are categorized by leaky-mechanism of the resonant cavity antennas (RCAs) These resonant cavity antennas are composed of partially reflective surface (PRS), which is properly placed above the ground surface plane and between PRS and ground plane multiple reflections perform inside the cavity, which increases the gain of the antenna by in-phase Propagation leaking from structure.…”

This paper presents a high-gain leaky-wave antenna based on a resonant cavity (RC) structure with the capability of unidirectional beam scanning over predefined frequencies and desired beam angles. Frequency scanning is achieved by implementing a properly-designed single-layer partially reflective surface (PRS) based on a simple ray tracing-based design procedure. In the proposed structure, two techniques are combined to make the beam scanning unidirectional. First, a metallic wall is placed at a proper distance from the radiator to suppress the antenna propagation at undesired directions. Second, a feed antenna with a tilted beam is designed as the main radiating element inside the cavity to radiate over desired beam angles. A prototype of the proposed antenna is fabricated and measured demonstrating a beam scanning from 12 o to 46 o over the frequency band from 25 to 31 GHz. Moreover, a maximum gain of 15.4 dBi is achieved at 26 GHz on the elevation plane with tilted angle of 22 o . The proposed leaky-wave antenna is suitable for various wireless applications, in particular the 5 th generation of cellular networks and small cell base station antenna (BSA) applications.INDEX TERMS Base station antenna (BSA), leaky-wave, resonant cavity (RC), millimeter-wave, partially reflective surface (PRS), small cell, 5G antenna, unidirectional beam steering.
