Abstract

We present a new low-profile composite right- and left-handed metamaterial zeroth order resonance (ZOR) antenna of the simulated and measured fractional bandwidth 30 and 57%, respectively, for a center frequency 2.5 GHz and gain over 3 dBi, while other ZOR antennas have narrow bandwidths much less than 10% with low antenna gain below or around 0 dBi. The proposed antenna shows the monopolar radiation pattern over the entire band. The design approach is verified by the circuit and 3D EM simulations, and measurement.
