A Novel Planar Switched Parasitic Array Antenna With Steered Conical Pattern

A novel planar switched parasitic array antenna has been proposed for wireless communication. Compared with conventional switched array antennas, this array antenna has more compact planar structure and steered conical elevation pattern. Simulation and measurement have been carried out to validate the design. PIN diodes and micro-controller unit (MCU) are used to implement a beam switching system. Experimental results show that this antenna has the capacity to provide beam switching.
