Abstract :
The radiation characteristics are presented for a three-element Yagi-Uda antenna enclosed in an electrically large Kaman radome. The discussion focuses on the influences of various structural parameters, such as the radome thickness, permittivity, size and the antenna position. The method of moments (MOM) is applied to the Yagi-Uda antenna, and the equivalent physical optics (PO) currents produced by the antenna radiation are then assumed on the radome wall. Calculation results indicate that radome parameters and the antenna position can affect the antenna radiation characteristics seriously.
