Abstract

A novel single-fed microstrip antenna with switchable polarization for four states by using just two PIN diodes is proposed. This antenna is suitable for wireless local area network (WLAN) systems. The advantage of this antenna is its simple structure, it contains a radiating circular patch, two switches (PIN diode), and a 50 Ω microstrip feed line. It can be switched between four different states: two states of linear polarization (LP), one state of left hand circular polarization (LHCP) and one for right hand circular polarization (RHCP).
