技術說明

本發明係關於一種多頻天線，包含：一介質基板、一接地面以及一輻射部。該接地面位於該介質基板上，並具有兩短路點。該輻射部包含：一支撐介質、一輻射金屬線以及一單極天線。該輻射金屬線位於該支撐介質上，其兩端點分別電氣連接於該接地面之兩短路點，使得該輻射金屬線與該接地面之一邊緣形成一封閉區間。該單極天線亦位於該支撐介質上，為該輻射金屬線所圍繞，且該單極天線之一端為訊號饋入點，而該訊號饋入點位於該輻射金屬線之兩端點之間。 The present invention is related to a multiband antenna. The antenna comprises a dielectric substrate, a ground plane and a radiating portion. The ground plane further comprises two short-circuiting points. The radiating portion further comprises a support dielectric material, a radiating line and a monopole antenna. The radiating line and the monopole antenna are formed on the surface of the support dielectric material. The two terminals of the radiating line are electrically connected to the two short-circuiting points, such that the radiating line and the ground plane form a closed loop. The monopole antenna is surrounded by the radiating line. One terminal of the monopole is the feeding point of the antenna and is located between the two terminals of the radiating line.
