Abstract:
1. A printed antenna assembly for the transmission of electromagnetic waves, the printed antenna comprising: a substantially planar circuit board having a first planar surface and a second planar surface, the first and second planar surfaces being parallel and spaced by a material thickness, the circuit board including a mounting section and an antenna section integrally formed with each other; an antenna driving circuit mounted to the first surface of the mounting section for generating electromagnetic waves to be transmitted by the printed antenna; a pair of radiating strips formed on the antenna section of the circuit board and coupled to the antenna driving circuit for the transmission of electromagnetic waves; and a pair of impedance matching strips formed on the antenna section of the circuit board and each coupled to one of the radiating strips, the impedance matching strips each having a length selected to substantially match the impedance of the antenna driving circuit.
