A Pattern Reconfigurable Antenna with Parasitic Rectangular Ring

A new method to reconfigure the radiation pattern of a simple triangular microstrip patch antenna is presented. The antenna consists of a central equilateral triangular patch andone Rectangular Ring parasitic. The parasitic ringuses two switch to reconfigure its radiation pattern. The radiationpattern of the proposed antenna can be reconfigured into threemodes. The antenna resonances at 5.3 GHz frequency and its bandwidth is 1 GHz.And very useful for making and using the systems are Wimax.
