摘要： The present invention relates to an active photonic band gap antenna. In this case, the photonic band gap structure is constituted by metal rods, some of which are discontinuous, namely composed of sections of rods connected by a switching element such as a PIN diode. According to the invention, only one rod in a row of rods seen from the radiating source is discontinuous. The antenna pattern can be controlled at a low cost.
