Radiation characteristics and generation of higher-order modes of circular microstrip antennas
Abstract
The characteristics of higher-order modes of circular microstrip antennas, such as radiation pattern, directivity, bandwidth, efficiency, and location of the feedpoint to match a 50 ohm line, are studied, and the effects of varying the substrate parameters are investigated. A multifeed technique to generate any particular mode is also presented.
