Design of a Truncated Circular Microstrip Patch Antenna with Slot for GPS Application

摘要

In the furtherance of technological evolution, the wireless communication system has its own contribution by providing an expanded number of technological devices among which microstrip antenna occupies a dynamic area. Microstrip antenna field has a variety of features and Global Positioning System (GPS) application is one of them. In this research work, a design has been proposed for civilian GPS (GPS L2 1.2276 GHz Band) utility purpose. The model is a circular patch having a slot and truncation on two sides which has been simulated using Computer Simulation Technology (CST) Microwave Studio Suite software. The results obtained from the simulation shows an impressive impedance matching having a return loss of around -31dB, RHCP (Right Hand Circular Polarization) on the desired frequency with a bandwidth coverage of nearly 41 MHz and also an overall gain of 6.55dBi. All these simulated outcomes from this unique proposed design satisfactorily suit with the GPS antenna characteristics.
