| 摘要 |
The invention provides a surface mount antenna (10), comprising: a substrate (2) made of at least one of a dielectric material and a magnetic material, said substrate (2) having a substantially rectangular prism shape and including a first major surface (2a) and a second major surface (2b); a ground electrode (3) disposed on said first major surface (2a) of said substrate (2); a radiation electrode (4) having a strip shape disposed at least on said second major surface (2b) of said substrate (2); a feeding electrode (5) disposed on at least one surface of said substrate (2); and said radiation electrode (4) including an open end portion (4a) and a plurality of grounded end portions (4a, 4c), said open end portion (4a) being arranged close to said feeding electrode (5) with a gap therebetween on said substrate (2), and said plurality of grounded end portions (4b, 4c) being connected to said ground electrode (3) on different portions of the substrate (2), respectively. The above described antenna has an enhanced gain without changes in size. <IMAGE> |
