Abstract
The invention provides a radiation pattern-reconfigurable wide angle scanning antenna. The antenna is characterized in that a coplanar waveguide 2, two feed network transmission lines 3, a bilaterallysymmetric SSPPs radiation carrier 4 and a patch 5 are all located on the same side of a dielectric plate 6, the two feed network transmission lines 3 are connected with two SMA RF connectors 1 and the bilaterally symmetric SSPPs radiation carrier 4, both SMA RF connectors 1 are connected with the coplanar waveguide 2, and the patch 5 is disposed on the bilaterally symmetric serrated SSPPs radiation carrier 4. The antenna is advantaged in that a radiation pattern can be reconstructed by exciting the bilaterally symmetric SSPPs transmission lines and adjusting phase difference between two ports, and the antenna has good reconfigurable characteristics of the radiation pattern and has wide operating frequency band, low profile and the reconfigurable radiation pattern.
Description
