Embodiment Construction

[0032] Hereinafter, the present invention will be further described in detail through specific embodiments in conjunction with the drawings.

[0033] Please refer to figure 1 , figure 1 The structure diagram of an S-band miniaturized ultra-wideband omnidirectional radiation vertical polarization antenna provided by the present invention includes: an antenna base 10, a main radiating unit 20, a parasitic radiating unit 30, a feed balance unit 40 and a video plug-in unit 50.

[0034] Wherein, the antenna base 10 is made of FR4 circuit board with double-sided copper-clad, dielectric constant between 3.8-4.4, and a thickness of 0.0088 times the wavelength. In this embodiment, the antenna base 10 has a rectangular structure as a whole, and the base length is 0.24. Times the wavelength, the length of the vertical side is 0.465 times the wavelength.

[0035] In this embodiment, the main radiation unit 20, the parasitic radiation unit 30, and the feed balance unit 40 are all processed on th...

Abstract

The invention provides an S-band miniaturized ultra-wideband omnidirectional radiation vertically polarized antenna. The S-band miniaturized ultra-wideband omnidirectional radiation vertically polarized antenna comprises: an antenna substrate; a main radiation unit arranged on the antenna substrate and used for radiating electromagnetic waves; a parasitic radiation unit arranged in the main radiation unit and used for being coupled with the main radiation unit to broaden the frequency band of radiated electromagnetic waves; a feed balance unit arranged on the antenna base body and used for impedance matching; and a radio frequency plugging unit arranged on the antenna substrate, wherein the feed cable radio frequency plugging unit is connected with the main radiation unit. According to theinvention, through multiple parasitic loading and coplanar waveguide feeding methods, the size of the antenna is effectively reduced, and the working frequency band of the antenna is expanded to reach 37.5% of the beneficial effect of an ultra wide band.

Description
