“…At around 300 GHz, the gain of the antenna is higher than 11 dBi, with more than 50% radiation efficiency. However, drastic gain fluctuations with the frequency are observed due to the narrow surface wave depression bandwidth [12].…”

This paper presents an on-chip 1 to 4 subarray element for wireless subharmonic injection (WSI) in the context of antenna-in-antenna THz oscillators. The proposed antenna receives the third-order subharmonic injection signal (STS) at 100 GHz from one side and radiates the 300 GHz fundamental oscillation signal (FOS) to the opposite side, which performs like a subharmonic transmitarray. Each element is consisted of a single SIS receiving antenna (Receiver antenna, RA) connected with a 2x2 FOS array (Transmitter antenna, TA). By positioning more FOS antenna around the single SIS antenna, the element spacing at 300 GHz is shorted within one wavelength which inhibits the grating lobe. Through tuning the distance of the FOS array element, the surface wave in the thick indium phosphide (lnP) substrate is also reduced to some degree. The simulation results show that the maximum radiation efficiency of the designed chip antenna structure is better than 50% in both the 100 GHz and the 300 GHz band. The conjugate impedance matching in the dual-band is achieved according to the active element requirement. Utilizing the antenna proposed in this work, a low injection loss is verified in the periodical boundary based WSI simulation.

“…The slots are positioned such that the surface waves that are generated by the slots and the patch interfere destructively, and, therefore, the radiation efficiency of the antenna is improved. An analysis of the radiation efficiency of two distant slots is presented in [17]. In Section IV, the analysis is extended to the case in which both slots and a patch are present.…”

Abstract-A balanced antenna design is presented that is tailored to broadband communication in the 60-GHz frequency band. The antenna can be realized in printed circuit-board technology, has a high radiation efficiency and can be used in array configurations. It is modeled with a method-of-moments implementation. The radiation efficiency is analyzed in detail, and design guidelines are given. Moreover, an optimization method is outlined that optimizes both antenna bandwidth and radiation efficiency. The antenna element and a circular antenna array have been realized. Measurements of these antennas are in good agreement with simulated results.Index Terms-Antenna arrays, antenna efficiency, antenna measurements, antenna optimization, millimeter-wave antenna, millimeter-wave antenna arrays, millimeter wave antennas, optimization methods.

“…At the same time, we encounter conceptual difficulties characteristic of the dipole antennas with thick dielectric layers in which excitation of surface waves is possible, which sharply deteriorates the antenna effectiveness [4]. For this reason, (i) very thin dielectric layers are often used [4], which decreases the mechanical strength of the antenna, several dipoles are included in parallel [5,6], which enlarges the antenna area, (ii) multilayered aperture-coupled antennas are used, or (iv) additional lenses are built in above the planar antenna [7]. It is evident that since such solutions are time-consuming, a slot antenna without the above disadvantages was developed.…”

We discuss the concept of developing a millimeter-wave multielement matrix receiver on the basis of planar antennas with directly coupled low-barrier Schottky diodes. Three main problems are considered which involve choosing and developing a design of the planar antenna coupled with the low-barrier Schottky diode, optimizing the parameters of the low-barrier Schottky diodes for obtaining maximum sensitivity, and ensuring compact arrangement with weak mutual influence of the planar detectors in a two-dimensional array. We propose a design of the slot antenna with an active resistance of about 800 Ω at a resonant frequency of 94 GHz. The detection characteristics of diodes with the differential Schottky-barrier resistance in the range R j = 0.4-1000 kΩ for a zero bias are studied experimentally. The mutual influence of the neighboring antennas is examined for developing the multielement radio-imaging system. The conditions of weak cross influence of the closely located planar detectors are determined.
