Description
Technical field
The utility model relates to antenna, particularly relates to a kind of mace microstrip.
Background technology
The form of microstrip antenna has a variety of.According to the difference of paster and floor form, its kind can be divided into micro-strip paster antenna, micro-strip oscillator antenna, microstrip slot antenna etc.Due to the shape of microstrip antenna self and the particularity of material, make the advantage that it has other antennas incomparable in a lot of field, such as, volume is little, lightweight, low throwing face, low cost of manufacture, technological requirement is low, robustness, planar structure easily and antenna carrier is surperficial conformal and with microwave radio integrated circuit and optoelectronic IC technical compatibility etc.So microstrip antenna undergoes an unusual development rapidly, just cause the very big concern in antenna works field short decades.Just because of this, microstrip antenna has been widely used in the markets such as person communication system (PCS), global positioning system (GPS), direct broadcasting satellite (DBS), WLAN (WLANS) and intelligent freeway traffic system (IVHS).But contradiction is always ubiquitous.Microstrip antenna also has self geneogenous shortcoming, as: bandwidth is narrower, and makes its radiation efficiency relatively low due to surface actuator, conductor and dielectric loss.Although some problem is not solved, one flaw cannot mar the jade, and microstrip antenna inherent advantages are that its development speed in field of antenna holds a safe lead.
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 mace microstrip, and technical scheme is as follows:
Mace microstrip comprises substrate, equilateral triangle radiation patch, circular radiation paster, impedance matching input transmission line, half-round metal ground plate; The upper surface of substrate is provided with seven equilateral triangle radiation patch, lay respectively at directly over circular radiation paster, left side, right side, upper left side, upper right side, lower left, lower right, and the center of adjacent two equilateral triangle radiation patch and the circle center line connecting angle of circular radiation paster are 45 degree, circular radiation paster, impedance matching input transmission line; The lower surface of substrate is provided with half-round metal ground plate; One end of impedance matching input transmission line is connected with circular radiation paster, and the impedance matching input other end of transmission line is connected with the bottom of substrate.
