CPW-Fed Wideband Pattern Reconfigurable Antenna

A coplanar waveguide (CPW) fed eight-shaped pattern reconfigurable antenna is proposed. The antenna is operated between the frequency range of 2.61-3.44 GHz. The antenna is capable of switching its pattern from omnidirectional to directional with two different switching conditions of the PIN diodes. An omnidirectional pattern is achieved when both diodes are in OFF states whereas directional patterns are achieved when alternatively any one of the diodes is in ON state and another is in OFF state. The simulated and measured results are in close agreement.
