Reflection Properties of three different Substrates on Circular Microstrip Patch Antenna

چکیده
Communication Systems are being investigated for S, C, X and Ku bands. For portable systems, the size and cost of the antenna are of great importance. Microstrip antennas show promise due to their small and conformal features, and their ability to be mass manufactured. The bandwidth and return losses are also of great importance. A project is currently underway to examine the characteristics of three dielectric substrates believed suitable for microstrip antenna applications in the X-band. These substrates are Bakelite, Er of 4.78 and tan δ of 0.03045, RT Duroid, Er of 2.2 and tan δ of 0.0004 and Polyester, Er of 1.39 and tan δ of 0.01 specified at 10 GHz frequency. A microstrip antenna is designed with triangular patch of fixed resonant frequency of 10 GHz and fixed height of 1.5 mm.
