ABSTRACT:
A radio frequency antenna having a microstrip feed network and a flared radiating structure directly fed by such microstrip feed network. A wedge-shaped dielectric structure is disposed in the narrow region of the flared radiating structure to match the impedance of the antenna to the impedance of free space. An E-plane array antenna includes a plurality of antenna elements, each including a single feed element on a dielectric board. An H-plane array antenna includes a plurality of feed elements on a single dielectric board. A cover, having an absorbing material, is disposed over the microstrip feed network to suppress stray radiation from propagating from such feed network.
