The invention discloses a double-frequency end-fire printed antenna. The double-frequency end-fire printed antenna comprises a dielectric slab, metal radiation oscillators, parallel strip lines, rectangular metal patches and metal reflection oscillators. The metal radiation oscillators, the parallel strip lines, the rectangular metal patches and the metal reflection oscillators form element units. The parallel strip lines are perpendicularly and eclectically connected with the metal radiation oscillators, the rectangular metal patches are perpendicular to the parallel strip lines, the rectangular metal patches are parallel with the metal radiation oscillators, gaps are reserved between the rectangular metal patches and the metal radiation oscillators, each metal reflection oscillator is in an L shape, and the two sides of each metal reflection oscillator are parallel with the corresponding metal radiation oscillator and the corresponding parallel strip line respectively. The element units are printed on the front side and the back side of the dielectric slab respectively and are symmetric with the parallel strip lines as the symmetry axes. A center feed pin of a feed connector is connected with the parallel strip line on the front side of the dielectric slab, and an outer conductor of the feed connector is connected with the lower layer of the parallel strip line on the back side of the dielectric slab. The double-frequency end-fire printed antenna is of a planar structure and is small in size, simple in structure and convenient to produce and machine.
Description
technical field [0001] The invention relates to the field of radio antennas, in particular to a dual-frequency end-fire printed antenna. Background technique [0002] Because the transmission distance of the directional antenna is longer than that of the omnidirectional antenna, it is often used for short-distance bridging in the wireless area network. With the rapid development of wireless communication, higher requirements are placed on the performance of antennas, and miniaturized, low-profile antennas have become important research contents for mobile communications. The printed Yagi antenna is a commonly used planar end-fire antenna, and in order to meet the needs of some wireless devices, dual-frequency printed Yagi antennas have appeared one after another. But the Yagi antenna has a narrow frequency band. Contents of the invention [0003] The purpose of the present invention is to provide a dual-frequency end-fire printed antenna with simple structure and effecti...
