Abstract
A high gain array using virtual-element Fabry Perot-Cavity Antenna (VE-FPCA) with near field split-beam that emulates a two-element slot array is presented. A novel frequency selective surface (FSS) design is used to split the source antenna beam into two in the near field. Each beam is circular and generated by a square aperture of horizontal slots within the FSS. Comparison of electric field magnitude, phase and beam separation is made between the FPCA system and two-element slot array in the near field. Feedline loss is also compared between both systems. The FPCA has a 5dB far-field gain improvement over the two-element array. It has a constant E-field phase in the E-plane, which is the result of an increased aperture efficiency.
