Compact Penta-Band Dual ZOR Antenna for Mobile Applications

Abstract EN

A compact penta-band dual zeroth order resonator (ZOR) antenna with band-stop filter is proposed for mobile applications.

The ZOR antenna is designed with modified mushroom-like structures extended on nonground region to obtain good efficiency and broad bandwidth.

This modified mushroom-like structure is confirmed as double negative (DNG) transmission line by full wave simulated dispersion relation.

Moreover, a bended patch and a band-stop filter (BSF) are employed to increase efficiency and bandwidth, respectively.

The length of each antenna is about λ0/10 at the resonant frequencies of 900 MHz and 1800 MHz, respectively.

The overall dimension of the antenna is 54.4 mm (length) × 4 mm (width) × 5 mm (height).

The total efficiencies in low and high bands are measured more than 40% and 70%, respectively.
