A Novel Dual Band Circular Microstrip Patch Antenna for Wireless Applications
A novel simple circular microstrip antenna of radius=16.625mm, a substrate of relative permittivity ?-4.2 and thickness h=1.6mm is proposed to operate for multiband applications. The measured frequencies are found to be 2.2875GHz and 2.475GHz.The simulation of the proposed antenna is done on IE3D software. 1. INTRODUCTION Microstrip antenna are used in communication systems owing to their advantages such as low profile, conformability, low manufacturing cost and easy association with other circuit components. Among the conventional microstrip antenna geometries, circular microstrip antenna is most widely analyzed antenna perhaps due to easy mathematical modeling and applicable boundary conditions.
