Abstract

This paper presents the analysis and design of broadband and compact zeroth-order resonant (ZOR) antennas based on truncated grounds. A ZOR unit cell, whose physical size is independent of the operating frequency due to the fundamental infinite wavelength, can be implemented with a composite right/left-handed (CRLH) or inductor-loaded transmission line (TL). The two types of ZOR antennas with extended bandwidth and more compact size are achieved by introducing the truncated grounds. It is also shown that the supported infinite wavelength can be used to generate a monopole-like radiation pattern. The characteristics of the broadband and compact size of the proposed antennas are verified by the simulated and measured results.
