Abstract

A novel extremely compact Zeroth Order Resonator (ZOR) antenna with a chip inductor, for Digital Video Broadcasting-Handheld (DVB-H) application, is presented. The proposed antenna has a bowtie structure with an overall dimension of 0.0186λ0 × 0.020λ0 × 0.003λ0 mm3 at 503 MHz. The zeroth resonance property makes the resonant frequency to be independent of the antenna dimension. The 3:1 VSWR bandwidth of the antenna is 39 MHz and offers an omnidirectional radiation pattern. A 99.1% reduction in the overall area of the structure is achieved compared to a conventional circular patch antenna operating at the same frequency.
