Study on a Parabolic Reflector Fed by L-band Multi-port Eleven Antenna

摘要

The paper studies the properties of the far field of a primary-fed parabolic reflector fed by a four-port L-band Eleven antenna. The sum beam as well as difference beams in two orthogonal planes after the reflector, which are necessary for the mono-pulse tracking, have been numerically evaluated. In addition, the relationship between the spacing between two parallel folded dipoles and the matching as well as radiation properties has been investigated.
