This paper presents a dual band frequency and polarization reconfigurable microstrip antenna. The simple design consists of two slots and two feeds. In one slot there is a switch. The two feeds are positioned on the right and left diagonal of microstrip antenna. When the switch is ON the electrical size of antenna becomes small and it resonates at higher UMTS 2100 MHz band with circular polarization. Similarly, when the switch is OFF then size of antenna is large and it operates at lower UMTS 1900 MHz band with elliptical polarization. The sense of polarization can be easily changed from right handed to left handed by changing the feed position. The radiation pattern is not disturbed by switch state and gain of proposed antenna is above 5 dBi. This antenna can be used in emerging reconfigurable wireless communication systems.
