Abstract
In this work we analyze the effect of EBG sidewalls in parallel plate slot antennas. Electromagnetic BandGap (EBG) structures present some interesting properties that may overcome so me of the problems of conventional technologies. Recently, several EBG structures have been proposed and demonstrated to be useful in enhancing performances of microwave circuits or antennas. We use these novel structures to realize a perfect magnetic cond
uctor (PMC) surface artificially. The results of the effect using PMC in comparison with perfect electric conductor (PEC) in the sidewalls of the parallel plate slot antennas is presented as examples of application. Using PMC sidewalls in this kind of antennas, relatively uniform
fields distribution are improved, so it allows to increase the directivity getting to enhance the efficiency of these
antennas.
