Patent ID: 7864132

Claim:
An active photonic band gap antenna (PBG) comprising, according to a plane of directions x, y, a radiating source and a photonic band gap structure constituted by parallel metal rods, perpendicular to the said plane, with rods extending between the radiating source and an outermost rod, the rods of diameter d repeating themselves n x times, wherein n x is an integer greater than 0, with a period a x in the direction x and n y times, wherein n y is an integer greater than 0, with a period a y in the direction y, the rods being constituted by continuous rods and discontinuous rods formed by at least 2 sections connected by a switching element making the rod continuous or discontinuous, (wherein) one of the rods of at least one row of rods seen from the radiating source is a discontinuous rod, and wherein the height of the rods between the radiating source and the outermost rod is increasing.
