Single-chip rectangular omnidirectional antenna

Abstract

The invention discloses a single-chip rectangular omnidirectional antenna. The single-chip rectangular omnidirectional antenna comprises a rectangular substrate, a U-shaped metal grounding sheet, multiple rectangular radiation sheets, a bending line metal radiation structure and a groove structure. The single-chip rectangular omnidirectional antenna aims at solving the problems that conventional omnidirectional antennas are low in gain, expensive in plate material and poor in omnidirectional performance. The single-chip rectangular omnidirectional antenna comprises the substrate 21, the U-shaped metal grounding sheet formed by the rectangular metal sheet 1, the rectangular metal sheet 2 and the rectangular metal sheet 14, the rectangular metal sheet 15, the rectangular metal sheet 3, the bending line metal radiation structure formed by the rectangular metal sheet 4, the rectangular metal sheet 5, the rectangular metal sheet 16, the rectangular metal sheet 17, the rectangular metal sheet 6, the rectangular metal sheet 7, the rectangular metal sheet 18, the rectangular metal sheet 19, the rectangular metal sheet 8, the rectangular metal sheet 9 and the rectangular metal sheet 20, and the groove structure formed by the rectangular metal sheet 10, the rectangular metal sheet 11, the rectangular metal sheet 12 and the rectangular metal sheet 13. The single-chip rectangular omnidirectional antenna is used for indoor and outdoor wireless coverage occasions.

Description

technical field [0001] The invention relates to an omnidirectional antenna, in particular to a monolithic rectangular omnidirectional antenna with good omnidirectionality, which belongs to the field of radio communication. Background technique [0002] Antennas can be seen everywhere, and it is closely related to our daily life. For example, a radio to listen to radio broadcasts needs an antenna, a TV needs an antenna, and a cell phone needs an antenna. Various forms of antennas can be seen in some buildings, cars, ships, airplanes, etc. The antennas used by radios and televisions are generally receiving antennas, while the antennas used by radio and television stations are transmitting antennas. The antenna of the mobile phone is shared by sending and receiving, but it must be forwarded and forwarded through the antenna of the mobile communication base station. In fact, all radio equipment (including radio communication, broadcasting, television, radar, navigation and ot...
