1. A linearly polarized r.f. radiating slot antenna structure comprising:

  • two separate electrically conducting coplanar generally rectangular plates formed as respective islands of metal etched from a common metal sheet and disposed on a dielectric sheet in a spaced apart relationship, said plates having respective first edges juxtaposed substantially within one plane and thereby defining said radiating slot,an electrically conducting ground plane disposed beneath said two plates and electrically connected to respective second edges of said plates by a plurality of separately formed metallic connections extending from said ground plane to said second edges of said plates, each said second edge being opposite its corresponding first edge in said one plane, thus defining an electrical cavity between said plates and said ground plane, andr.f. feed means connected to at least a first one of said two plates.
