Array Thinning with Periodic and Aperiodic Distributions in a Fabry-Perot Cavity for Gain Enhancement

摘要

We explore the possibility of using periodic and aperiodic arrangements of sources inside a Fabry-Perot Cavity (FPC) made of a ground plane and a partially reflective surface (PRS), as in Fig. 1. The cavity is used to enhance the gain of each source [1]-[6]. The enhanced gain permits to design array antennas with large distances between the radiating elements without the occurrence of secondary lobes [7].
