Abstract:
A surface mount circularly polarized wave antenna comprising a substrate comprising an insulating material and having a first main face, a second main face, and at least one side face extending between said first main face and said second main face;a first ground electrode disposed on said first main face of said substrate;a radiation electrode having a substantially rectangular shape and disposed on said second main face;a feeding electrode disposed on said one side face of the substrate extending from the first main face of said substrate, and toward the second main face, one edge of said feeding electrode being positioned near to one side of said radiating electrode;a second ground electrode disposed on the same one side face of said substrate where said feeding electrode is disposed, and being electrically conductively isolated from said feeding electrode and electrically conductively connected to said first ground electrode; anda degeneracy separation element provided in relation to said radiation electrode for causing radiation of a circularly polarized wave from the radiation electrode.
