“…The former concept is not very suitable for array signal processing while the latter needs a large RF substrate area and extensive patch design. In [2] a cylindrical lens fed by microstrip patches was proposed for producing individual beams in the E-plane and the H-plane, which correspond to the elevation plane and the azimuthal plane of the roadside scenario, respectively. In our work we extend this concept by placing a uniform linear array (ULA) of patch-subarrays along the focus line of the cylindrical lens.…”

This paper introduces a novel dielectric lens antenna configuration for automotive radar applications. A cylindric lens fed by a uniform linear array (ULA) accomplishes elevation beam shaping and simultaneously allows for the application of array signal processing in the azimuth plane. Measured and simulated radiation patterns show a superior performance compared to a conventional antenna concept without lens.

“…Lens antennas with a beam switching capability are better than a traditional phased antenna array due to the latter's excessive metallic and phase shifter losses, specifically at higher frequency bands (24 and 77 GHz) [13]. In 2005, Colome et al [14] introduced a cylinder lens fed by microstrip patches with a dual feed to increase the isolation between the transmitter and the receiver for bistatic radar at 24 GHz. This antenna achieves a gain of 15.3 dB and an HPBW of 21.30 and 37.80 for the E-plane and the H-plane, respectively.…”

“…Based on the work in ref. [14], Weing et al [15] introduced the same idea by placing a uniform series antenna array along the focus line of a lens. In the elevation (YZ) plane, the lens was fed by a column of a series of microstrip patch antennas.…”

This paper introduces a novel antenna array synthesis for radar systems based on the concept of a virtual antenna array (VAA) and the method of moments/genetic algorithm (MoM/GA) synthesis method. The VAA concept is applied to both scanning and fixed radiation pattern arrays. The proposed VAA is introduced to simultaneously support the medium-range radar (MRR) and the long-range radar (LRR) with beam width ±7° for LRR and ±37° for MRR. The proposed VAA is distinguished by its minimum number of antenna elements, simple feeding network, high efficiency, and gain, but all of these are at the expense of a large aperture antenna size compared to the planar antenna array (PAA). The VAA has the ability to have the feeding network and the radiating elements on the same layer, as compared to the multilayer PAA. The newly proposed concept is analyzed and verified analytically and experimentally. Two orthogonal (16 elements) VAAs are designed to operate in the frequency range from 23.55 to 24.7 GHz and to support a flat-shoulder shape (FSS) radiation pattern for LRR/MRR. The antenna was fabricated and tested experimentally, and good agreements between the simulated and measured results were noticed. The proposed VAA is introduced to solve the problems of large size, low isolations, low efficiency, feeding network, low resolution, and small coverage range for the antenna arrays of automotive radars. The proposed antenna array is introduced for automotive radar applications at 24 GHz.
