Abstract

A partially reflective metamaterial surface is designed to have in‐phase reflection property for the purpose of reducing the height of resonant cavity antennas. Since the reflection phase of the in‐phase is close to 0° at the operating band, the cavity height, that is, the distance between the metamaterial surface and the PEC ground, can be reduced from half wavelength to about a quarter wavelength, without using an artificial magnetic conductor as the ground. An example antenna is designed, fabricated, and measured to demonstrate the concept. © 2009 Wiley Periodicals, Inc.
