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 paper, the authors presented ZOR antenna which excites dual resonances. The second resonance is obtained by placing two stubs and an outer ring.
