DEVELOPMENT OF AN ELLIPTICAL ANNULAR RING MICROSTRIP ANTENNA WITH SINE WAVE PERIPHERYBy M. Baharuddin, V. Wissan, J. T. Sri Sumantyo, and H. KuzeAbstract: We have investigated elliptical annular ring microstrip antennas having a sine wave periphery both theoretically and experimentally. The proposed antenna gives a good circular polarization at the center frequency of 1.296 GHz, with measured 3 dB axial ratio bandwidth of about 0.73% (9.5 MHz) and impedance bandwidth of about 1.7% (22.0 MHz). Input and radiation characteristics are also examined for different sine wave amplitudes applied to the periphery of elliptical ring patch antenna.
