技術說明

本發明係關於一種多頻單極天線，包含：一介質基板 、一接地面、一輻射金屬部及一匹配電路。該接地面位於該介質基板上。該輻射金屬部位於該介質基板上，與該接地面不互相重疊，該輻射金屬部並包含：一第一金屬部，其一端為天線饋入點，該天線饋入點並大致位於該接地面之ㄧ邊緣處，其另一端則為開路；一第二金屬部，其一端與該第一金屬部具有一特定間距，另一端為開路。該匹配電路位於該介質基板上，其一端連接至一信號源，另一端連接至該天線饋入點。 The present invention is related to a multiband monopole antenna. The antenna comprises a dielectric substrate, a ground plane, a radiating metal portion, and a matching circuit. The ground plane is located on the dielectric substrate. The radiating metal portion comprises a first metal portion and a second metal portion and is located on the dielectric substrate, without overlapping the ground plane. One end of the first metal portion is the feeding point of the antenna, and the feeding point is located near one edge of the ground plane. The other end of the first metal portion is electrically open. One end of the second metal portion has a predefined distance from the first metal portion, and the other end of the second portion is electrically open. The matching circuit is located on the dielectric substrate. One end of the matching circuit is connected to a source, and the other end of the matching circuit is connected to the feeding point of the antenna.
