Abstract
The invention discloses a trough type omnidirectional antenna, comprising a first radiation sheet, a second radiation sheet, a third radiation sheet, a medium substrate, a bottom plate, a fixed plate and a feed line, wherein the first radiation sheet is perpendicular and orthographical to the second radiation sheet; a trough line is arranged between the first radiation sheet and the third radiation sheet; the first radiation sheet and the third radiation sheet are installed on the medium substrate; the third radiation sheet is connected with the bottom plate; the fixed plate is installed beneath the bottom plate; and the feed line passes through the bottom plate and the fixed plate and is connected with each radiation sheet. In the invention, because the perpendicular patch technology is adopted, the occupation space of the antenna is effectively reduced; and because a structure of an orthographical parasitic unit is adopted for the antenna, a radial direction map of an azimuth plane can be improved very well, the out-of-roundness of the antenna is enhanced and the omnidirectional characteristic requirement of the antenna is satisfied.
Description
Technical field
The present invention relates to a kind of communication antenna, relate in particular to a kind of slot type omnidirectional antenna that transmits and receives radio signal, belong to the Wireless Telecom Equipment technical field.
Background technology
Existing antenna product is to design at different working frequency range mostly, stock size and volume are all bigger, the communication system independent design that has nothing in common with each other, can be compatible or compatible degree depend on the bandwidth and the cost of antenna system, and be the directional antenna product mostly.Though broadband omni-directional antenna product few in number is also arranged, complex structure, design is loaded down with trivial details, versatility is poor, the processing cost height, and there is certain defective in performance.For example biconical antenna and single-stage sub antenna with its preferably broadband character obtained widely using, comparatively complicated but it is made, cost is higher, bandwidth can not well satisfy mobile communication (800 ~ 2500MH
Z) demand.Along with radio communication equipment and electronic message unit develop the hot subject that is designed to domestic and international mobile communications industry research of miniaturization, broadband omni-directional antenna towards multifunction, miniaturization, ultra broadband and the friendly direction of coordinating with surrounding environment.It relates to the wideband impedance match technology of antenna, the optimal design of miniature antenna profile, be suitable for the design of the miniature antenna broadband matching network that the different districts signal covers and the technical barriers such as integrated design of multiband common antenna, but the antenna of a plurality of frequency ranges is integrated into a kind of trend that a kind of antenna structure is current technical development, also is the motive force that realizes device miniaturization.Therefore, develop miniaturization, broadband omni-directional antenna simple in structure, with low cost is very necessary.
Summary of the invention
The objective of the invention is provides a kind of slot type omnidirectional antenna in order to overcome the deficiencies in the prior art.
The technical solution used in the present invention is: a kind of slot type omnidirectional antenna, comprise first radiation fin, second radiation fin, the 3rd radiation fin, dielectric substrate, base plate, fixed head and feeder line, described first radiation fin and the second radiation fin perpendicular quadrature, be the line of rabbet joint between first radiation fin and the 3rd radiation fin, first radiation fin and the 3rd radiation fin are installed on the dielectric substrate, the 3rd radiation fin is connected with base plate, fixed head is installed below the base plate, described feeder line passes base plate and fixed head, and is connected with each radiation fin.
It is that 140 millimeters Lawn lamp beautifies the body omnidirectional antenna that the present invention can be used for body of rod diameter.
Beneficial effect: the present invention adopts vertical mount technology, effectively save taking up room of antenna, simultaneously higher radiation gain can be arranged, the consistency that good radiation consistency and gain are arranged in working band, and antenna adopts the structure of quadrature parasitic element, can be good at improving the antenna pattern of azimuth plane, improve antenna
Deviation in roundness, satisfy omnidirectional's characteristic demand of antenna.
