IMPROVEMENT OF ACTIVE PHOTONIC FORBIDDEN BAND ANTENNAE

摘要

The invention relates to an active photonic forbidden band antenna. The photonic forbidden band structure consists of metallic rods (2,3), some of which are discontinued (3), i.e. they consist of sections of rods connected by a switching element such as a PIN diode. According to the invention, only one rod (3) in a row of rods, as seen from the radiating source (1), is discontinued. The antenna diagram can be economically controlled.
