Under it is unaffected.Antenna uses planar structure, its design size flexibly, efficiency high, simple structure, low cost, small volume,
Practical value is high.Therefore extensively using in a wireless communication system.
Background technology
From 2002, FCC (FCC) passes a resolution allowed 3.1-10.6GHz frequency ranges to be applied to commercial field,
UWB communication systems with high data transmission rate, low cost, low-power consumption and strong antijamming capability are developed rapidly.Should
There must be following features for the antenna of UWB communication system terminals：Such as linear phase response, the antenna pattern of omnidirectional,
Stable gain.Therefore, ultra-wideband antenna is designed to for one of significant challenge of UWB systems.Planar printed-antenna,
Such as rectangle, hexagon, ellipse hexagon, butterfly monopole, dipole etc. with broadband, low dispersion, low-loss, low is cutd open
Face, it is lightweight, be easy to make, it is cheap the advantages of, be widely used to UWB communication systems.
With the development of indoor high-speed wireless data access technology, it is desirable to which wireless communication system has bigger data throughout.
Ultra-wideband communication system is increasingly taken seriously.UWB antennas do not require nothing more than antenna has small volume, good radiation efficiency, complete
To coverage property, while should avoid being interfered with other communication systems, the main communication frequency band for overlapping has
WLAN (5.15-5.825GHz) and WiMAX (5.25-5.85GHz) communication system, in order to avoid diving for WLAN and WiMAX
In interference it is necessary to be filtered to 5.15-5.825GHz.Therefore, the ultra-wideband antenna with band-stop response is received widely
Concern research.
