Method of providing increased low-angle radiation sensitivity in an antenna and an antenna having increased low-angle radiation sensitivity |
摘要 |
An improved low-angle radiation antenna is obtained through excitation of a tangential electric field on the high-impedance surface, as well as leaky transverse-electric surface waves. Such fields and surface waves cannot normally occur on an ordinary metal surface. The tangential electric field on the high-impedance region excites a transverse-magnetic surface wave on a surrounding metal surface which gives improved low-angle radiation in the E-plane of an antenna disposed on the high impedance surface. Leaky transverse-electric surface waves provide improved radiation in the H-plane of the antenna.
