New Configuration of Microstrip Patch Antenna Arrays
Abstract
A new configuration of a Microstrip patch antenna array is presented in this paper. The array is arranged in such a way that only one patch placed in the E-plane and four patches are placed in the H-plane. This is to make the antenna provide a dual band performance and increase the gain. The feeding network utilized in the array is based on the step-loaded matching structure in order to maintain good matching impedance between the input port and the radiation (out) ports. The antenna array is simulated using the Computer Simulation Technology (CST) Microwave Studio. The gain of the first frequency band, which has the center frequency 4.35 GHz, is 8 dBi, while the second band is 5.8 dBi at the center frequency 9.8 GHz. Due to simplicity and high gain, the antenna array is of interest of many high gain and long distance applications such as point-to-point communication systems.
