“…A ray method has been used to demonstrate the performance of the FP resonant cavity antenna. 17 Usually, the FPRC [18][19][20][21][22] consists of two parts, one is the ground plane and the other is the upper plane, we ignore the edge effect and assume that the two planes are uniform. The ground plane has a complex reflection coefficient jФ 1 , the cladding has a complex reflection coefficient jФ 2 , and the operating wavelength is λ.…”

A monopulse antenna loaded with Fabry–Perot resonator (FPRC) of X‐band for the application of monopulse radars is designed, fabricated, and measured in this letter. The proposed antenna is composed of an FPRC, a feed source that integrates aperture‐coupled microstrip antennas with a sum–difference comparator. The simulation and measurement have demonstrated that the aperture efficiency of the antenna reaches 46%, and the measured gain of the sum beam is 14.8 dBi which is 4.4 dBi higher than the monopulse antenna without an FPRC. The null depth of the difference beam is under −20 dB. The proposed monopulse antenna is of low‐profile, low cost, and simple structure, which can be applied in radar and wireless communication systems.

“…За счет использования в качестве полупрозрачного зеркала специальной частотно-селективной поверхности (ЧСП), которая имеет положительный наклон фазы отраженной волны [4,5], условие резонанса может удовлетворяться в довольно широком частотном диапазоне, достаточном для функционирования в некоторых системах связи. Известны случаи достижения полосы рабочих частот 30% и более [6,7], однако КИП таких резонаторов находится на уровне 20−40%. В открытых источниках не представлены образцы резонаторов с полосой более 10% и КИП более 50%.…”

The work is devoted to the development and study of the antenna array based on Fabry-Perot cavity in the radio band. The antenna array element in the form of a Fabry-Perot cavity with circular polarization is proposed, the semitransparent mirror of the cavity is realized in the form of a two-layer frequency-selective surface (FFS). A power divider based on thin waveguides to feed the antenna array with size 2x8 was developed. А model of the antenna array was manufactured. The power divider is made by laser cutting of sheet aluminum, semitransparent resonator layer is made by photolithography. The total efficiency of the antenna array was about 50% in the 5% frequency band with a VSWR of no more than 1.5.
