Abstract-A novel printed monopole antenna covering 2.4-2.484 GHz (Bluetooth), 2.5-2.69 GHz (IMT-E) and 3.1-10.6 GHz (UWB) frequency bands is presented. The entire frequency bands are obtained by a modified U-shaped radiator and a modified ground plane. To prevent possible interference between UWB systems and other existing wireless systems such as WLAN and WiMAX, a SCRLH resonator structure is placed next to the feed line. Characteristics of the Bluetooth and IMT-E bands are further enhanced by two quarter-wavelength strips added on each side of the radiator. The proposed antenna can be easily printed on a 1.6-mm-thick FR4 substrate with dimensions of 30 × 41 mm 2 . Simulation and experimental results show that the antenna yields an impedance bandwidth of 2.3-2.8 and 3-12 GHz with −10 dB reflection coefficient, except for the dual notched bands of 3.2-3.6 for WiMAX and 4.9-6.1 GHz for WLAN. The electrical characteristics in frequency and time domain show suitability of this antenna for use in UWB systems.

“…Whereas this was useful, they do not indicate how the calibration was achieved, nor do they provide the reasons for the adopted calibration technique. Other researchers have measured certain UWB channels, however they have not explained whether a calibration process was in fact used at all (Bellens et al, 2009;Donlan et al, 2006;Katayama et al, 2006;Keignart and Daniele, 2002;Kobayashi, 2006;Nakahata et al, 2008;Nkakanou et al, 2011a;Nkakanou et al, 2011b;Bieder et al, Dec.2006;Abbasi et al, 2011;Gelabert et al, 2011;Elmansouri and Filipovic, 2011;Chen et al, 2009). …”

approach to ultra-wideband channel calibration using a vector network analyser," Australian Journal of Electrical and Electronics Engineering, vol. 11, (4) pp. 347-356, 2014. An approach to ultra-wideband channel calibration using a vector network analyser AbstractIn this paper, two calibration methods are investigated to determine the most suitable approach for ultrawideband (UWB) communication channel measurements. The fi rst method is the through, open, short and match (TOSM) calibration technique. The second method is through, refl ection and load calibration technique. Presented experiment results show that the through, refl ection and load calibration process is more precise for calibration of coaxial cables and the UWB channel as clearly seen by increased magnitudes of the channel transfer function. It is also shown that the proposed through, refl ection and load technique leads to an improved larger measured root-mean-square value and that the measured magnitude transfer function of the wireless channel is increased by an absolute value of approximately 5 dB after calibration compared with results achieved when TOSM technique is used. In the paper, it is also shown that the time delay associated with test equipment of the UWB channel measurement can be equally well removed by using either the through, refl ection and load or TOSM calibration techniques.

“…In this paper, the effects of two-arm equiangular and Archimedean spiral antennas' pulse dispersion on the (BER) performance of the time hopping pulse position modulation (TH-PPM) impulse radio are analyzed. Also the dispersion compensation technique, introduced in [2], is used to enhance the performance of spiral antennas as pulse radiators.…”
