“…Compared with microwave communication, THz communication has a larger transmission capacity, better confidentiality, and stronger anti-interference ability. And THz communication has low photon energy and good penetration of dust and smoke compared with optical communication, which can ensure the reliability of communications in harsh environments [5][6][7][8][9]. However, the development of related functional devices, such as the THz antenna and filter, is essential to realize efficient THz communication [10][11][12].…”

A high-gain and tri-band terahertz microstrip antenna with a photonic band gap (PBG) substrate is presented in this paper for terahertz communications. Polyimide dielectric columns are inserted into the silicon substrate to form the PBG substrate to improve the gain of the antenna. The PBG substrate and polyimide substrate constituted a multilayer substrate structure and enabled the multi-band operation of the antenna. The PBG substrate antenna achieves gains of 6.28 dB, 4.84 dB, and 7.66 dB at resonant frequencies of 0.360 THz, 0.580 THz, and 0.692 THz, respectively, outperforming the homogeneous substrate THz microstrip antenna (H antenna) by 1.18 dB, 1.74 dB, and 1.82 dB, respectively. The radiation efficiencies at three operating bands are over 93%, 92%, and 88%, respectively, which are slightly higher than that of the H antenna and greater than that of the standard multi-band antenna.

“…Recently, extensive research has been conducted on integrated circuits and terahertz antennas for remote sensing, imaging, biology, radars, medical applications, and wireless communications [ 5 – 9 ]. Terahertz frequencies that ranging from 0.1 to 10 terahertz are located between the microwave and far-infrared spectrum [ 10 – 12 ]. The wavelength of terahertz radiation is longer than the infrared wavelength.…”

In this paper, a novel compact planar coronavirus antenna is proposed for wide band applications. In the design of this antenna, the idea of the radiating part has been taken from the 3-D model of the coronavirus, which is fed by a 50 Ω coplanar waveguide. The patch structure and the feed line of the proposed antenna, which have been made of gold, are located on a polyamide substrate with a thickness and dielectric constant of 45 µm and 3.5, respectively, and the antenna has compact physical dimensions of 300 × 300 µm 2 . The simulation results of the antenna have been analyzed in terms of S 11 , VSWR, radiation pattern, gain and surface current distribution. The designed antenna covers the frequency band from 0.3627 to 0.5918 THz for S 11 ≤ − 0 dB with a fractional bandwidth of > 47.98% and with a bandwidth ratio of 1.63:1. This extended bandwidth coverage allows the antenna to be suitable for a wide range of applications including wireless communications, internet of things, wearable devices, on-chip antennas and multiple-input multiple-output systems. Also, the results of the far-field show an omnidirectional radiation pattern with an average gain and efficiency of 4 dBi and 93% throughout the frequency band, respectively.

This paper presents a novel antenna design with an enhanced gain-bandwidth product for modern communication networks, including 5G systems. The design is consistent with 17 unit cells of a composite right/left-hand (CRLH) structure with an electromagnetic band gap of Hilbert inclusions. Therefore, the resulting design occupies an area of 40 × 200 mm 2 of a Taconic RF-43 substrate. The maximum antenna gain is 16 dBi at 5.5 GHz, which is very applicable for long-range communication systems. Nevertheless, the antenna performance is controlled with optical switches of light-dependent resistors (LDR) technology. Therefore, the antenna performance is tested with different switching seniors to investigate the possibility of reconfiguration scenarios at various frequency bands. However, the antenna gain is highly affected by changing LDR switching status; for example, at 5.5 GHz, the antenna gain is varied between 7 and 16 dBi. Thus, the proposed antenna is an excellent candidate for direct amplitude modulation. Finally, the antenna simulation results and measurements agree very well with each other.
