Rhombus Shaped Reconfigurable Microstrip Antenna for CDMA Wireless Applications

Rhombus Shaped Reconfigurable microstrip antenna is designed to operate at 1.74GHz. The proposed antenna is a Rhombus shaped microstrip antenna which gives a good size reduction with good impedance bandwidth in terms of with and without capacitor. The Designed antenna is expected to reduction in size and increase in Bandwidth. The Simulation is carried out by using IE3D software and practical results are measured by Vector Network analyzer. Comparative analysis has made between with and without capacitor as a lumped element. The size reduction of Rhombus shaped Reconfigurable microstrip antenna with capacitor gives best possible size reduction of 75.95% with overall bandwidth 86MHz. Acceptable agreement is obtained between the simulated and measured antenna performance parameter.
