Title: RECONFIGURABLE HALF-WIDTH LEAKY-WAVE ANTENNA
Abstract:
There is disclosed a reconfigurable, leaky-wave antenna device comprising: a groundplane; a septum extending substantially perpendicularly from the groundplane and extending along a length thereof; a first main microstrip transmission line having first and second opposed lengthwise edges, the first edge connected to the septum, the first main microstrip transmission line extending substantially parallel to and above the groundplane to one side of the septum; and a first subsidiary microstrip transmission line, arranged alongside the second edge of the first main microstrip transmission line. The first main and first subsidiary microstrip transmission lines are connected to each other at a plurality of points along their respective lengths by reconfigurable electronic components.
