Abstract:This paper presents a single-feed switchable feed network that combines four ports of the microstrip patch antennas using the two microstrip/negative-refractive-index (MS/NRI) coupled line coupler. When a two-way quarter wavelength transmission lines, which are terminated by an antenna and each resonant frequency of the antennas is very closely located, it acts as an ideal single-pole double-throw (SPDT) switch. The MS/NRI coupled line coupler was used to achieve tight backward-wave coupling (-3 dB) and port i… Show more
