Substrate Height and Dielectric Constant Dependent Performance of Circular Micro Strip Patch Array Antennas for Broadband Wireless Access
Micro strip patch antennas get more and more important in these days. This is mostly due to their versatility in terms of possible geometries that makes them applicable for many different situations. The lightweight construction and the suitability for integration with microwave integrated circuits are two more of their numerous advantages. Corporate series feed circular micro strip patch array antennas have been designed for three different substrate heights and dielectric constants of substrate. Bandwidth and radiation pattern have been analyzed by using General Electro-Magnetic Solver (GEMS). Effect of bandwidth due to change of substrate height and dielectric constant have been investigated. Finally, bandwidth for each substrate height and dielectric constant are measured for selecting the optimal patch array antenna.
