- - Broadband Patch Antenna with Ground Plane of L-shape and U-shape

摘要

1. Description of the invention;A patch antenna for a mobile communication system in which a radiator is in the form of a patch;2. Object of the invention;It provides a broadband patch antenna that can achieve broadband impedance matching as well as achieving excellent front-to-back ratio with small ground plane.;3. Composition of invention;A patch for copying the wireless signal; A feed line for feeding the patch; A ground surface having a base disposed to face the patch, and at least one bend bent at an edge of the base and extending in a direction in which the patch is disposed; And a connector for connecting the feed line to an external system.;4. Effect of invention;It has good front-to-back ratio while reducing the ground plane size, can reduce the overall size of the antenna, low manufacturing cost, and can easily change the beam width of the antenna.
