Abstract

In this paper, a concept of a simple circularly polarized antenna with partially reflecting surface (PRS) has been adopted for precision farming applications. The investigation contains an analysis of the dependence of the antenna performance on the elements number in the PRS structure in X- and Ka-band frequencies. Especially meaningful parameters from point-to-point connectivity perspective are axial ratio less than 3 dB and high gain of the antenna. Simulation results show that all antennas proposed in the paper comply with these requirements providing the gain greater than 13 dBic in any case. All of the presented designs have high efficiency and also are characterized by a compact size and lightweight.
