“…The horn and lens antenna has higher radiation efficiency and isolation than conventional antennas such as series-fed antenna and comb-line antennas [23][24][25][26][27][28]. For example, the radiation efficiency of the horn and lens antenna is about 1.6 times higher than that of a series-fed antenna [16].…”

Long-range radars (LRRs) for higher level autonomous driving (AD) will require more antennas than simple driving assistance. The point at issue here is 50-60 % of the LRR module area is used for antennas. To miniaturize LRR modules, we use horn and lens antenna with highly efficient gain. In this paper, we propose two high-density implementation techniques for radio-frequency (RF) front-end using horn and lens antennas. In the first technique, the gap between antennas was eliminated by taking advantage of the high isolation performance of horn and lens antennas. In the second technique, the RF front-end including micro-strip-lines, monolithic microwave integrated circuits, and peripheral parts is placed in the valley area of each horn. We fabricated a prototype LRR operating at 77 GHz with only one printed circuit board (PCB). To detect vehicles horizontally and vertically, this LRR has a minimum antenna configuration of one Tx antenna and four Rx antennas placed in 2×2 array, and 30 mm thickness. Evaluation results revealed that vehicles could be detected up to 320 m away and that the horizontal and vertical angle error was less than +/-0.2 degrees, which is equivalent to the vehicle width over 280 m. Thus, horn and lens antennas implemented using the proposed techniques are very suitable for higher level AD LRRs.

“…A THz antenna, providing an efficiency of 93% with a maximum gain of 5.60 dBi, operating between 0.258 THz to 0.385 THz is circularly polarized, where slots are used in the linear strip antenna [9]. A 16-element array, providing a peak gain of 15 dBi, achieves resonance at 77 GHz, which is useful for automotive applications [11]. A fractal antenna, with dimensions 800×600×81.29 μm 3 , provides a bandwidth of 9 THz (0.30 THz to 9.30 THz).…”

This communication reports a conformal offset feed Quasi-Yagi antenna at 300 GHz for high-directional applications. A novel offset feed mechanism is adopted to obtain directional behavior from a conventional planar structure. The proposed antenna is designed on a Silicon-dioxide (SiO 2 ) dielectric substrate having a permittivity (ε r ) of 4 and a height of 60μm. A gold material of thickness 5µm is used as a conducting metal in the top and bottom layers. This antenna consists of an offset feed patch, partial ground as a reflector, and three director elements forming a Quasi-Yagi antenna. This conformal structure operates from 270 GHz to 333 GHz and provides a peak gain of 8.62dBi at 300 GHz in the end-fire direction. An analysis of different metals and parametric variation in metal thickness, substrate thickness, patch length, and width is also reported for a better understanding of the evolution of the proposed structure. A lumped equivalent circuit is also developed for the proposed structure to study its transmission line model. A good agreement is also noted between the EM simulation (HFSS, CST) and circuit simulation (ADS).

In this article, A bi-planar receiving antenna is planned for LTE convenient base stations. The proposed reception apparatus involves two parts one for the upper band and another for lower band. It can in like manner be shown without granulating folds. The lower band has the pair of printed dipoles with two or three parasitic parts for transmission limit improvement. The upper band contains a few crumbled dipoles. The microstrip line and dipole are cut on a comparative substrate. The upper band segments are wrapped in lower band segments encircling a diminished structure. The bi-planar receiving wire achieves an information transmission of around 2 GHz. The arranged receiving wire can be completed in versatile base stations. The radio wire increase achieved around ~12 dbi which is sensible for the adaptable correspondence base station structures.
