ABSTRACT:
An antenna is provided on a circuit board which has an elongated stub, having an end connected through the dielectric circuit board to a ground plane. The combination of the ground plane, stub and dielectric forms a resonant cavity. The resonant frequency of the cavity is adjustable by selectably sorting through holes provided in the end of the stub opposite to where the reference ground plane is connected to the stub.
