A Pattern Reconfigurable Patch Antenna with Parasitic Circular Ring

A new method to reconfigure the radiation pattern of a simple Circular microstrip patch antenna is presented. a Circular ring shaped parasitic radiator is electromagnetically coupled with the Circular shaped patch. The parasitic radiator uses four switch (currently short and open for the proof of concept) to reconfigure its radiation pattern
