Technical field
The present invention relates to a kind of antenna, particularly a kind of novel miniature wing ultra-wideband antenna.This antenna is to be imprinted on a very small size of substrate.
Background technology
Antenna is the part that institute's wire/wireless communication system is indispensable, carry the signal sent by transmitter and change into electromagnetic form with to spatial transmission, or the electromagnetic signal in free space is changed into high-frequency signal for receiver reception, thus realizing the spacing wave exchange process of radio communication.Development along with wireless communication technology, the continuous progress of hardware research and development condition, in order to realize the transmission of wireless signal better, to the performance of antenna it is also proposed higher requirement, under the wide variety of overall situation of current Wireless Telecom Equipment, the importance of antenna grows with each passing day especially, the major opportunity that the research of various antenna technologies and the requirement of higher technical specification make antenna technology welcome another development.
Ultra-wideband Communication Technology (UWB, UltraWideBand), has just had associated ultra-broadband emitter and the application of receiver technology, but has simply been applied in the fields such as radar, location, sensing and secret communication as far back as the sixties in 20th century.2002, FCC (FCC) is using the 3.1～10.6GHz operating frequency range as work system and the system of measurement, and specify except being applied to the fields such as digital communication, radar and location, all right commercialization, civil area etc., along with the development of radiotechnics, system also becomes more and more higher ultra-broadband signal for the requirement of transmission speed, transmission capacity can meet the demand of modern communications well owing to having the advantages such as great bandwidth, transfer rate height, low, the strong interference immunity of power.
Ultra-wideband communication system has the characteristic not available for narrow-band communication system, and it can bring low-power consumption, high bandwidth and relatively simple wireless communication technology for the interface card of WLAN WLAN and PAN (Personal Area Network) PAN and access technology.
Along with the development of radiotechnics, ultra-wideband antenna develops to directions such as broadband, miniaturization, high transmission rates, low cost, low-complexities.Ultra-wideband printed monopole aerial is exactly this development product.In the design of ultra-wideband printed monopole aerial, has plenty of the bandwidth carrying out broadening antenna by changing the structure of metal floor；Have plenty of and increase bandwidth by change feeder line；Also there is the bandwidth carrying out broadening antenna by changing the shape of radiation patch.Ultra-wideband communication system covers 3.1～10.6GHz frequency range, and the wireless systems such as wireless communication frequency band densely distributed such as WLAN, WiMAX and the WCDMA in this frequency range are all in this frequency range.In order to reduce between system exist interfere, it is desirable on the basis of low complex degree, realize system compatible, spectrum reuse, it is possible to make ultra-wideband antenna itself have band-stop response, so having occurred as soon as the ultra-wideband antenna with band-stop response.
Summary of the invention
It is an object of the invention to provide a kind of novel miniature wing ultra-wideband antenna, antenna has good impedance operator and radiation direction characteristic at the frequency band range of 5.32GHz 14.28GHz, the voltage standing wave ratio (VSWR) < 2 in working frequency range.In 7.63GHz 8.47GHz scope, there is trap characteristic, and trap is adjustable.
