EZR-MZR Resonators for Compact Low-Profile Omnidirectional Circular-Polarized Antenna Design
IEEE Photonics Journal, 2017 New zeroth-order resonator (ZOR): the curved EZR-MZR resonator [epsilon-zero resonance (EZR) and mu-zero resonance (MZR)] was proposed for circular-polarized (CP) antenna design with low-profile and omnidirectional characteristics.
