Design Methods Of Wearable Dipole Antennas And Ultra-wide Band Antenna

The wearable dipole antenna and ultra-wide band (UWB) antennas are analyzed inthe thesis. The author’s major contributions are summarized in two aspects: A practicalwearable antenna is presented in part one according to the requirements. A dualband-notched planar ultra-wideband printed antenna for WLAN and WiMAXapplications are designed in part two.The use of a30PF capacitor, the wearable antenna is well matched. The simulationand measurement results show that the proposed antenna can operate at37~350MHzfor VSWR<2and the bandwidth is313MHz. Moreover, a novel compact slot antenna ispresented. The slot antenna is fed by a microstrip line and radiates from the widetrapezoidal slot. The bandwidth of the slot antenna is120%(3GHz-12GHz) which cancover the whole UWB frequency band and provide dual band-notched function innarrow frequency bands at around3.5GHz and5.8GHz. It can be seen from thefar-filed radiation patterns that the slot antenna is omni-directional in the H plane. Thus,the slot antenna can be exempt from the interference with existing WLAN and WiMAXoperating bands and can be applied to UWB applications.
