Abstract :
A switched-beam microstrip patch antenna is proposed to demonstrate the capability of beam steering by controlling MEMS switches on/off. Simulated and measured results show that two sets of connection states can be obtained at 9.08 GHz and the return losses are less than -15 dB. State 1 provides three quasi-conical half power beams in the second, third and fourth quadrants of the upper half space. State 2 provides three quasi-conical half power beams in the first, second and third quadrants of the upper half space.
