“…These antennas are very wideband in nature. A 3/2 λ bow tie antenna coupled to a MOM (metal oxide metal) diode designed at 28 THz [25] has the potential for use in arrays of antenna-coupled IR detectors.. A Planar antenna in the form log-periodic spirals or twin slots or twin dipoles [26], mounted on the back of a dielectric lens, is a typical configuration that is used in astronomical receiver for sending signal to a quasi-optical mixer [27]. This structure has the advantage that it can be easily fabricated along with the mixing device on the same substrate P. J. Burke [28] photoconductive terahertz antenna with radial symmetry has been reported in [30].…”

In this paper we review THz radiation properties, generation methods, and antenna configurations. This paper suggests some new class of antennas that can be used at THz frequency, like optical antennas or Carbon nanotube antennas. THz technology has become attractive due to the low energy content and nonionizing nature of the signal. This property makes them suitable for imaging and sensing applications. But at the same time detection and generation of THz signals has been technologically challenging. This paper presents a comparative study of the generation techniques for THz frequency signals giving emphasis to the some new techniques like Quantum Cascade lasers which has created significant research interest. The main aim for this study is to find out the materials suitable for fabricating THz devices and antennas, a suitable method for generation of high power at THz frequency and an antenna that will make THz communication possible.

“…Traditionally, since the heat capacity of most bolometers scales with the area, antenna coupling structures have been used to reduce the bolometer physical dimension [12], at the cost of a more complex FPA architecture (e.g., fly's eye lens arrays [13] or horn arrays [14]). Instead, in [15], the use of FPAs of bare absorbers was proposed for tightly sampled large format configurations, i.e.…”

Passive imaging cameras at millimeter and submillimeter wavelengths are currently entering a new era with the development of large format arrays of direct detectors. Several of these arrays are being developed with bare absorbing meshes without any antenna coupling (lens or horn) structures. The design of such arrays is typically done resorting to geometrical considerations or basic broadside plane wave incidence analysis. This paper presents a spectral technique for the analysis of such focal plane arrays in reception using Fourier Optics, which is valid also for moderately skewed incident angles. The analysis constitutes a step improvement with respect to previously used methods by providing an accurate and efficient way to estimate the point-source angular response and the throughput from a distributed incoherent source of an absorbing mesh in the focal plane of a quasi-optical component (e.g. a parabolic reflector or lens). The proposed technique is validated with full-wave simulations. After presenting the analysis, the paper compares the performance of arrays of bare absorber in the focal plane of a quasi-optical component to those of corresponding antenna based arrays. It is found that absorbers lead to a comparable trade-off, in terms of spill-over and focusing efficiency, only for very tight samplings. For larger samplings, the focusing efficiency of absorbers is significantly lower than the one for antennas.

“…Many of the papers are concerned primarily with the solid-state devices rather than with the antenna, and are not discussed here. A variant on the printed circuit flat TEM horn is the square linear taper horn with dipole feed at the mouth opening; the horn walls are etched and metallized on a thick substrate, as in the feed (Guo et al, 1991;Rebeiz et al, 1990;Rebeiz and Rutledge, 1992).…”
