摘要

We present a new application of uniplanar compact electromagnetic bandgap (UC-EBG) structures in antenna-beam shaping for indoor mobile communications. Such UC-EBGs are used to construct Fabry-Perot-type cavities in which the enhanced directivity can be achieved from conventional patch antennas. This paper demonstrates that an antenna beam can be shaped by shifting the defects (patch antennas) from the centre of UC-PBG cavities. The theoretical predictions are verified by numerical simulations and measurement results, and it appears that antenna-beam shaping in UC-EBG cavities can achieve the same radiation patterns as complex planar-antenna arrays used for improving the quality and strength of sent/received signals in mobile base stations.
