摘要：

The microstrip patch is one of the most preferred antenna structures for low cost and compact design of wireless communication systems and RF sensors. However, as applications move to higher frequencies, conventional patch antenna designs encounter severe limitations such as narrow bandwidth, low gain and surface wave losses. Photonic band-gap (PBG) technology has been considered a promising new solution to these problems. In this article , a novel two-dimensional (2-D) PBG lattice and its application in microstrip patch antenna design are described. The Ku-band PBG patch antenna demonstrates an improvement in bandwidth by a factor of 3.4 and 1.6 dB higher gain when compared with a reference patch on a conventional dielectric substrate.
