“…So far, the achieved output power is in the order of 1 mW at 300 GHz for UTC-PDs. Therefore, THz UTC-PD sources, integrated with antennas, are still at a research level, although some prototypes have been successfully demonstrated [10][11][12][13].…”

“…The stacking approach enhances the upward radiation. A THz-enabled antenna is proposed in [76], and shows that an efficient power coupling between the antenna and source, results in a considerable improvement in the performance of the antenna. Moreover, the layering concept is used in [77] to build up a simple printed Yagi-Uda antenna, which uses two different substrates, i.e.…”

Imperceptible latency, uninterrupted communication, and the availability of inexhaustible bandwidth are conceptualized as essential milestones to revolutionize the modes by which societies generated, circulate, receive, and perceive information. The exponential increase in wireless data traffic has raised concerns to investigate suitable bands in the radio spectrum to satisfy the intensifying user's data rate requirements. Overall the wireless infrastructure needs development and exploitation to synchronize with the massive capacity and connectivity demands. The Terahertz (THz) frequency band (0.1-10 THz) is considered as a pivotal solution to fulfill the needs of applications and devices requiring the high speed transmission, and have received noticeable attention from the research community. Technologies in this spectrum are facing rapid development and hold high potentials in applications like ultra-fast short-range wireless communications, remote sensing, biological detection, and basic material research. The antenna is one of the critical components to support the THz systems and require a considerable attention in terms of precision. Compact high-gain antennas are desirable for low latency and high data rate THz wireless communication systems, specifically for applications having space limitation, for example, in the high speed interlink inside the high density wireless communication base station (BS). Nevertheless, there still exist many challenges, while designing the antenna for THz communications requiring innovative solutions. This paper serves an introductory guideline to address the challenges and opportunities, while designing a THz enabled antenna.

“…For antenna dimensions of a few microns (at THz frequencies), proper impedance matching for this antenna is difficult. The planar horn antenna, on the other hand, radiates the signal energy along the substrate, whilst radiation perpendicular to the substrate would be more desirable [8]. An elevated patch antenna was proposed to suppress the substrate effects, however, the bandwidth still narrow [9].…”

Abstract-In this paper, a broadband bow-tie slot antenna is presented. The coplanar waveguide (CPW) fed antenna is fabricated on an InP substrate for same chip integration with the promising resonant tunnelling diode (RTD) terahertz (THz) oscillator which has the capability of room temperature operation and with relative high power. The antenna exhibits a very wide bandwidth (return loss S11 <-10 dB) around the design frequency (300 GHz). However, the radiation pattern is degraded because of the large dielectric constant of the InP substrate. A technique to overcome this problem employing a reflector ground plane underneath a thin substrate of low dielectric constant is presented. Initial simulation results of this technique are reported and experimental validation at lower frequency (17 GHz) shows the feasibility of the concept.
