Krushna A. Munde, Veeresh G. Kasabegoudar . A Zeroth-Order Resonance Patch Antenna for Dual Band Operations with Broad E-plane Beam Widths. International Journal of Computer Applications. 103, 7 ( October 2014), 7-11. DOI=10.5120/18084-9127
In this paper, design of probe fed zeroth order resonance (ZOR) antenna with dual frequency operation is presented. The mushroom structure is placed at the center of the geometry and the grounded via to have the desired ZOR response. The feed is connected between the inner ring and the mushroom structure. There are several ZOR antennas are available in literature with only one resonant frequency. However, in this work we presented ZOR antenna which excites dual resonances. The second resonance is obtained by placing two stubs and an outer ring. Also, it may be noted that we get nearly broader E-plane beamwidths (112 and 90 degrees) at both the resonance frequencies. The bandwidth of 7. 8% at second resonant frequency was obtained as compared to the conventional patch antennas (2~3%). At first resonance only narrow band performance was observed. Measured results fairly agree with the simulated data.
