Abstract


This paper presents a reconfigurable focal plane array (FPA) for lens or reflector based antenna systems in the 24 GHz ISM band. The FPA consists of five equal uniformlyspaced antenna elements with switchable polarization, fabricated on a four layer substrate using conventional low-cost PCB technology. For compactness and increased bandwidth, the design is based on aperture-coupled patch radiators on top of the substrate, each embedded in a cavity in order to reduce mutual coupling. Feeding is done by means of two orthogonal H-shaped slots which are excited by microstrip transmission lines etched on the bottom layer. A discrete pin-diode single pole, double throw (SPDT) switch directly below the patch allows for polarization control and facilitates a compact element size of 10mm x 10 mm including the cavity walls. Another discrete pin-diode SP5T switch allows the selection of one of the five FPA elements at a time.
