Analysis of E- Plane Radiation Patterns of a Simulated Scalar Feed Horn Antenna
Simulated scalar feed horn antennas are found to be exhibiting identical radiation characteristics of metallic corrugated feed horn antennas of same dimensions. Hence, in this paper, the e-plane radiation characteristics of a simulated scalar feed horn antenna is analyzed theoretically by extending the theory of metallic corrugated horn antennas. The theoretical e-plane radiation patterns at different frequencies in X-band are compared with that of experimentally obtained e-plane radiation patterns. Even though the nulls of the radiation patterns are not fully realized by the theory, the main beam characteristics are well explained.
