Abstract：A micro-strip shorted antenna with Compact Electromagnetic Band-Gap structure (CEBG) is presented. A shorted antenna with identical dimensions on a conventional ground plane is also included, so that a direct performance comparison can be made. Measured data shows a gain improvement of 3dB and a significant reduction in cross polarization for the CEBG antenna. Meanwhile it also proves that to design the same resonant frequency, the CEBG structure cell size is only about 50–60% of conventional structure, and this is significant in realizing EBG micro-strip phased antenna array.
