A Review onDesign of a high gain Microstrip Antenna using Parasitic Patch for GPS Application
GPS patch antennas are gaining their importance nowadays due to their importance in the communication engineering. This paper proposes a novel approach to increase the gain of microstripantenna.The application of gap-coupled mechanism for achieving high gain with microstrip antenna has been proposed .This present work includes the designing of patch antenna for the applications of Global positioning systems antenna in the handheld equipment. The antenna will operate at the desired frequency of 1.57GHz with 80 MHz bandwidth. An FR4 substrate of dielectric constant 4.4 and dielectric loss tangent of 0.027 is used in this present work. The proposed antenna possesses an average gain of 4.0 dB overall the GPS L1 operation. Return loss, input impedance smith chart, 3D gain, radiation patterns and field distributions are simulated and presented in this paper by using commercial Ansoft-HFSS software.
