Abstract
A metal lens is provided for length compacting a horn antenna across a frequency bandwidth. The metal lens includes a feed guide segment having an input cross-section, an intermediate segment, and an exit segment. The feed guide segment receives a signal from the horn antenna along a carry direction; an intermediate segment that expands from the input cross-section laterally to the carry direction. The intermediate segment incorporates an intermediate split vane perpendicular to the carry direction to divide the signal along the carry direction. The exit segment incorporates a plurality of terminating split vanes lateral to the carry direction for transmitting the output signals.
