Reconstruction of electric-field waveform radiated from UWB device by using the complex antenna factor
نویسندگان
چکیده
This paper describes the waveform reconstruction method of the electric field emitted by UWB (ultra wideband) device by using the complex antenna factor and observed waveform with an oscilloscope. The waveform radiated by a doubleridged guide horn antenna and an impulse generator was measured by an oscilloscope and was reconstructed by the method. The peak power measurement using a resolution bandwidth of 50MHz specified in the document of Federal Communications Commission (FCC) part 15 was examined.

UWB Planar Conical Horn-Shaped Self-Complementary Bow-Tie Antenna
An ultra-wideband (UWB) self-complementary planar bow-tie antenna (SCPBTA) is proposed. The antenna consists of a printed conical horn-shaped (CHS) radiator and a counterpart CHS slot etched on a rectangular ground plane. The printed CHS radiator is connected directly to the 50Ω microstrip line by bending the end portion of the feed line. As a result, the antenna has a simple structure which do...
متن کاملULTRA WIDEBAND SYSTEMS TECHNOLOGIES AND APPLICATIONS SPECIAL SECTION Angular-spectral antenna effects in ultra wideband communications links
In traditional approaches to antenna characterisation, spectral and angular dispersion are modelled separately. In the paper, the dependence of the power radiated from ultra wideband (UWB) antennas jointly on frequency and direction is established experimentally. It is demonstrated that both omni-directional and directional antennas typically exhibit higher directivity with frequency, with the ...
متن کاملAnalysis of motor fan radiated sound and vibration waveform by automatic pattern recognition technique using “Mahalanobis distance”
In recent years, as the weight of IT equipment has been reduced, the demand for motor fans for cooling the interior of electronic equipment is on the rise. Sensory test technique by inspectors is the mainstream for quality inspection of motor fans in the field. This sensory test requires a lot of experience to accurately diagnose differences in subtle sounds (sound pressures) of the fans, and t...

In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition) a...
