Abstract

An azimuthally omni-directional antenna for radio waves comprises a dielectric lens (3) having an elliptic surface in verti­ cal plane (1) and a reflector arrangement (2) which cooperate to focus rays (4) onto an array of elements at the surfacial plane (5). Local oscillator power can be injected and mixed.
