Abstract

The present invention discloses a compact broadband omnidirectional vertically polarized antenna. The antenna comprises a top-layer metal radiating sheet, a lower-layer dielectric plate, a middle metal column and a plurality of shorting-circuit metal columns. The lower-layer dielectric plate is provided with a hollow region. An upper end of the middle metal column is connected with the top-layer metal radiating sheet. A lower end of the middle metal column extends towards the hollow region. Upper ends of the shorting-circuit metal columns are connected with the top-layer metal radiating sheet.Lower ends of the shorting-circuit metal columns are connected with an upper surface of the lower-layer dielectric plate. After a microstrip feeder penetrates through the hollow region of the lower-layer dielectric plate, the microstrip feeder is connected with the lower end of the middle metal column. The present application proposes a method for introducing a capacitive reactance load into a floor slit, so that an antenna obtains a new resonant mode, and forms double-resonance operation in combination with a resonant mode obtained by introducing an inductive reactance load into a short-circuit metal bar, so that the antenna obtains good omnidirectional vertically polarized radiation characteristics within a wide range.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a compact broadband vertically polarized omnidirectional antenna. Background technique [0002] Omnidirectional antenna refers to a device that can realize 360° receiving and receiving electromagnetic waves in the azimuth plane without dead angle. Vertically polarized omnidirectional antennas have been widely used in military and civilian fields such as indoor precise positioning, WIFI coverage, Bluetooth device reception, GPS signal reception, and radar sensors. With the rapid development of wireless communication technology and the great improvement in the performance of semiconductor devices, it is necessary for the front-end antenna responsible for transmitting and receiving electromagnetic wave signals to have the characteristics of small size, low profile, and high integration. This makes omnidirectional vertically polarized antennas with compact structures ...
