Abstract

In this paper, a compact planar zeroth-order resonator (ZOR) antenna based on epsilon negative (ENG) transmission line is presented. Thanks to the zeroth-order resonance with the aid of virtual ground, we accomplish this proposed antenna with the size of only 0.053λ0 × 0.157λ0 × 0.0096λ0 at 3.580 GHz without destroying the overall substrate. The ZOR characteristic has been analyzed using provided Bloch and Floquet theory. The measured (simulated) bandwidth is about 15 MHz (10 MHz), and the measured (simulated) peak gain is about 2.60 dBi (2.68 dBi), respectively.
