Embodiment Construction

[0019] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] As shown in Figures 1 and 2, the high-gain omnidirectional antenna of the present invention includes a microwave dielectric substrate 1 and a multi-section microstrip line, wherein the microwave dielectric substrate 1 is composed of an upper microwave dielectric substrate 1a and a lower microwave dielectric substrate The composition of 1b is to print multi-section alternately fed striplines on the microwave dielectric substrate 1 by using a printed circuit board process. Increasing the number of stripline sections increases antenna gain.

[0021] Each section of the stripline is composed of an upper metal grounding plate 2a, a lower metal grounding plate 2b and a metal conductive strip 3 sandwiched between two layers of microwave dielectric substrates. The upper metal ground plate 2a is printed on the upper surface of the upper micro...

Abstract

The invention discloses a high-gain omnidirectional antenna, which comprises an upper microwave dielectric substrate (1a) and a lower microwave dielectric substrate (1b), wherein multiple sections of alternately-fed strip lines are printed on the microwave dielectric substrate; each section of strip line consists of an upper metal grounding plate (2a), a lower metal grounding plate (2b) and a metal conduction band (3); the upper metal grounding plates (2a) are printed on the upper surface of the upper microwave dielectric substrate (1a); the lower metal grounding plates (2b) are printed on the lower surface of the lower microwave dielectric substrate (1a); the metal conduction bands (3) are positioned between the upper microwave dielectric substrate (1a) and the lower microwave dielectric substrate (1b); and each metal conduction band is longer than each metal grounding plate and extends to the metal grounding plate of a microstrip line which is adjacent to the metal conduction band; and the metal conduction bands of two adjacent sections of the strip lines are alternately connected with the metal grounding plates through metallized through holes (4). The high-gain omnidirectional antenna disclosed by the invention is favorable in omnidirectional radiation property, simple in assembly process, good in process implementation uniformity and high in reliability.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a stripline high-gain omnidirectional antenna. Background technique [0002] An omnidirectional antenna refers to an antenna that covers 360 degrees in azimuth, and a high-gain omnidirectional antenna generally refers to an omnidirectional antenna with a maximum gain of more than 3dBi. High-gain omnidirectional antennas usually use several omnidirectional antenna elements to form a linear array in the longitudinal direction to achieve high gain. [0003] At present, the feeding methods of high-gain omnidirectional antennas widely used at home and abroad are mainly divided into two types: series feeding and parallel feeding. Parallel-fed omnidirectional antennas require an additional feed network in addition to multiple antenna elements to achieve wider impedance matching, but the existence of the feed network often affects the out-of-roundness of the omnidirectional radiation p...
