Abstract
The invention discloses a microstrip antenna side radiation appliance, aiming at designing the microstrip antenna side radiation appliance with low cost and easy control of radiation direction. The technical scheme of the invention is as follows: the microstrip antenna side radiation appliance comprises a microstrip antenna; a radiation patch is arranged at the center of a dielectric substrate; and the periphery of the dielectric substrate is provided with a metal film. The metal film is a copper sheet. The microstrip antenna side radiation appliance has simple structure, low cost and good use effect.
Description
Technical field:
The present invention relates to microstrip antenna, particularly a kind of microstrip antenna side radiation appliance.
Background technology:
Microstrip antenna is because it has low section, easily and the aircraft general character, cost is low, advantages such as easy making, be widely used, particularly in communication equipment especially mobile communication, use the square meter paster antenna especially widely, the radiation characteristics of microstrip antenna are: the wave beam main radiation direction is perpendicular to the paster surface, the size of looking the antenna ground level has back lobe radiation in various degree, but in many use occasions, beam position need be changed into situation non-perpendicular to the paster surface, the research report that this respect is also arranged in recent years, but the scheme of being studied is all comparatively complicated, design cost is very high, and radiation direction is wayward.
Summary of the invention:
It is low to the objective of the invention is to design a kind of cost, the manageable microstrip antenna side radiation appliance of radiation direction.Technical scheme of the present invention is, microstrip antenna side radiation appliance, and it comprises microstrip antenna, it is characterized in that: radiation patch is arranged on the dielectric substrate center, is provided with metallic film on the dielectric substrate periphery.Described metallic film is a copper sheet.The present invention is simple in structure, and is with low cost, and result of use is good.
Description of drawings:
Fig. 1 is a structural representation of the present invention, Fig. 2 is the structural representation of the embodiment of the invention 1, Fig. 3 is the embodiment of the invention 1 antenna pattern, Fig. 4 be the embodiment of the invention 1 S parameter schematic diagram, Fig. 5 is the H face directional diagram of the embodiment of the invention 1, Fig. 6 is the structural representation of the embodiment of the invention 2, Fig. 7 is the embodiment of the invention 2 antenna patterns, Fig. 8 be the embodiment of the invention 2 S parameter schematic diagram, Fig. 9 is the H face directional diagram of the embodiment of the invention 2
Embodiment:
Describe embodiment in conjunction with the accompanying drawings in detail,
The present invention uses the HFSS Electromagnetic Simulation software of being produced by ansoft company, can simulate different specific embodiments according at the different radiation direction demand of microstrip antenna,
Embodiment 1,
Radiation patch 1 is arranged on dielectric substrate 2 centers, on the dielectric substrate periphery, be provided with metallic film 3, the concrete radiation direction that is set to come with metallic film control antenna in two opposite flanks of dielectric substrate, controlling party to film have two groups, every group of five pasters, the paster width is 2mm, and the spacing of two adjacent patch is 6mm.Highly be the height (4mm) of dielectric substrate, the dielectric constant of substrate is 4.75.(in conjunction with Fig. 2)
The check simulation result, the antenna main radiation direction is pointed to 45 degree directions as can be seen.(in conjunction with Fig. 3)
Radiation patch 1 is arranged on dielectric substrate 2 centers, on the dielectric substrate periphery, be provided with metallic film 3, the concrete paster that is set on two of dielectric substrate relative sides, paste varying number, the y negative direction is three pasters, the y positive direction is two pasters, the paster width is 0.5mm, highly is 4mm, two adjacent patch spacing 2mm.The dielectric constant of substrate is 4.75.(in conjunction with Fig. 6)
The check simulation result, the antenna main radiation direction is two opposite directions as can be seen.(in conjunction with Fig. 7)
Concrete enforcement structure of the present invention is comparatively simple, can effectively control the radiation direction of microstrip antenna, greatly reduces the production cost of the controlled microstrip antenna of radiation direction.
