Abstract

A low-profile omnidirectional zeroth-order resonator (ZOR) antenna based on a mushroom structure is proposed in this paper. The mushroom structure as a transmission line has negative, zero, and positive propagation constant depending on its operation frequency. Zeroth-order resonance, of which length is independent of the physical length, is naturally presented. In particular, mushroom ZOR antenna generates a uniform vertical electric field against ground plane, so that it omnidirectionally radiates in a horizontal plane. The operation frequency, absolute gain, and gain variations for omnidirectional radiation of the designed prototype are 7.8 GHz, 3.1 dBi, and 2.05 dBi, respectively. Details of the antenna design and the simulated results are discussed
