Description
Technical field
The utility model relates to antenna, particularly relates to a kind of V collar jacket microstrip.
Background technology
In radio communication and radar system, antenna is the interface unit of free space and transmission line.Microstrip antenna is a class more novel and rising among multiple antenna, and as far back as nineteen fifties, just someone proposes this concept of microstrip antenna, but the research only having some fragmentary in Two decades years thereafter.Up to the seventies, microstrip antenna research just achieves breakthrough, has succeeded in developing the microstrip antenna of a collection of practicality.Afterwards, along with the fast development of science and technology, microstrip antenna theory or application depth and broadness on all achieve further development, and demonstrated it application on great potential.
Along with the development of microwave integrated technology and space technology are to the active demand of low profile antenna, expand in the world and microstrip antenna extensively and is in depth studied.In addition, modern age, development communication technologies was rapid, and required transmission rate is more and more higher, and bandwidth is also more and more wider.Ultra-wideband Communication Technology is large with high speed, safety, capacity, the advantage not available for other narrow-band communication systems such as anti-multipath is subject to extensive concern.Broadband, new construction and high performance microstrip antenna continue to bring out.Ultra-wideband microstrip antenna has larger frequency band range, can meet the demand of each frequency range.Therefore, in the urgent need to working out small size, frequency band range is wide, the micro-strip paster antenna that radiation characteristic is good.
Summary of the invention
The utility model provides a kind of V collar jacket microstrip, and technical scheme is as follows:
V collar jacket microstrip comprises square substrate, V collar jacket shape radiation patch, rectangular metal ground plate; The upper surface of square substrate is provided with V collar jacket shape radiation patch; The top of V collar jacket shape radiation patch is connected with the top of square substrate, the shape of V collar jacket shape radiation patch is provided with the slot isosceles trapezoid radiation patch of groove and a rectangle of bottom of isosceles triangle by of top and forms, the bottom of V collar jacket shape radiation patch is connected with the bottom of square substrate, and the lower surface of square substrate is provided with rectangular metal ground plate; The bottom of rectangular metal ground plate is connected with the bottom of square substrate.
Described square substrate is glass-epoxy material, and the length of side of square substrate is 23mm ~ 25mm.The upper bottom side length of the isosceles trapezoid of the upside of described V collar jacket shape radiation patch is 17mm ~ 19mm, and the length of side of going to the bottom is 23mm ~ 25mm, and waist is long is 16mm ~ 18mm; The bottom side length of isosceles triangle groove is 5mm ~ 7mm, and waist is long is 3mm ~ 5mm; The length of rectangle is 17mm ~ 19mm, and width is 6mm ~ 8mm.The length of described rectangular metal ground plate is 23mm ~ 25mm, and width is 9mm ~ 11mm.
It is good that the utility model has radiation characteristic, and structure is simple, small size, and cost is low, is easy to make, is convenient to the advantages such as integrated.
