Abstract
The radiation patterns of a slot antenna placed on a photonic band gap crystal have been measured. We used a layer-by-layer photonic band ga p crystal having a three-dimensional stop band between 12 and 15 GHz. The slot antenna radiation depends sensitively on the relative positio n and orientation of the slot in the surface unit cell of the photonic crystal. We have found configurations of the slot antenna with an inc rease of radiated power by 2-3 dB. The photonic band gap crystal can c onsiderably improve the performance of a simple slot antenna.
