Abstract
The present invention provides a near-magnet antenna. The near-magnet antenna includes an antenna, a substrate and a feed port. The substrate has an irregular shape, and the irregular pattern consists of a concentric circle and an "L" shape. The antenna is a monopole antenna, and the monopole antenna consists of a monopole and a top load. One end of the monopole is a feed end, and the other end is connected to the top load. The top load has a circular arc shape. When the antenna of the present invention is used, the antenna is pressed under a loudspeaker, and the substrate below the loudspeaker has a concentric circle ring shape, and does not impede the function of the loudspeaker; meanwhile, the use of a concentric circle ring ensures the underlay height below the loudspeaker to be consistent, thereby facilitating the installation of the loudspeaker and at the same time preventing interference on equipment which has waterproof requirements. The antenna can effectively reduce the affects of the loudspeaker magnet on the antenna, and can maintain relatively high gain and a large bandwidth. The antenna can be conveniently used for near-magnet applications and has a low cost.
