ABSTRACT:
A linearly polarized r.f. radiating slot is formed by the juxtaposed but separated and unshorted edges of two electrically conducting plates disposed above a ground plane. R.f. feedline is connected proximate the slot edges and, preferably, distributed therealong so as to provide a more uniform feed. In a non-resonant embodiment, lumped reactance (preferably plural discrete devices distributed along the slot length) is connected across the slot so as to form a resonant antenna structure. Both the slot and the r.f. feedline are preferably formed by photo etching techniques commonly used for the construction of printed circuits.
