A trough waveguide antenna that has a septum and opposing bases and side walls. In one embodiment, the bases are undulated and asymmetrically disposed about the septum. The magnitude, periodicity and length, etc., of the undulations may be varied for performance. The configuration of the septum may be similarly varied. Other mechanisms for achieving energy radiation are also disclosed as are cost effective fabrication techniques.
