- Title
Low-profile resonant cavity antenna based on an in-phase metamaterial surface.

- 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.
