Abstract (en)
The antenna choke is used to reduce the choke of current which mutually couples adjacent array sections. In order to simplify manufacture, a single channel (6) is machined between each row of array sections (2,4), the channel effectively reduces the ground plane current between the various sections. The choke allows for a relatively easy manufacturing process in which the array is built by sequentially placing conductive type sealant between the adjacent sections and bolting or securing the sections in place. The array sections include a number of radiating elements (10) which may be of any form for example rectangular waveguides or dipole radiators. <IMAGE>
