“…In fact, remarkable advances have been made in UWB antenna designing within the past few years. The main stream technologies include monopole antenna [22][23][24], slot antenna [25][26][27][28] and printed antenna [29,30]. In experiment, UWB planar antenna is based on the popular triangular monopole design technology [31][32][33], with the voltage standing wave ratio (VSWR) less than 2.25 across the working band.…”

“…Therefore, it is important to evaluate the distortion and its effects on the presented synchronization technique. Planar monopole UWB antennas are popular choices for UWB communications due to their attractive electrical, mechanical and economical merits [27][28][29][30][31][32][33][34]. Normalized transfer functions, H N, T x (f ) and H N, Rx (f ), of planar monopole UWB transmitting and receiving antennas [35] can be obtained, respectively [19].…”

Abstract-Synchronization performance of a pulse-based ultrawideband (UWB) system is investigated by taking into account of distortions caused by transmitter and receiver antennas and wireless propagation channels in different environments. The synchronization scheme under consideration can be achieved in two steps: a slide correlator and a phase-locked loop (PLL)-like fine tuning loop. Effects of the non-idealities are evaluated by analyzing the distortion of the received UWB pulse and subsequently the synchronization performance of the pulse-based UWB system. It is found that generally a smaller step is required for the sliding correlator due to distortions introduced by the antennas and channels. However, the fine tuning loop can always be stabilized by adjusting the loop parameters. Therefore, synchronization can always be achieved.

A Planar Multifunctional Four-Port Antenna System for Sub-Urban Mobile Tablet

A planar multifunctional four-port antenna system integrated on one substrate applied in the suburban mobile tablet is presented in this paper. The types of these antennas are selected based on different functions and the interactions between them are analyzed and reduced. Two identical T-shaped printed monopole antennas are designed for the MIMO mobile ad-hoc networks (MANET) application. The mutual coupling between the ports of these two MANET antennas is decreased by introducing a decoupling metal strip loaded with an inductor. Two horizontal printed dipoles with parasitic strips are developed to operate in the satellite navigation and communication frequency bands. Through the analysis of the interaction between the MANET antenna and satellite antennas, the satellite antennas with improved broadside radiation patterns are obtained. The performance stability of the proposed antenna system is verified by the investigation of the performances in different gestures. A prototype of the antenna system is fabricated and the measured results show that the proposed antenna system can cover the frequency bands of MANET communication, satellite navigation, and satellite communication with good performances. This proposed multifunctional antenna system is a good choice for the suburban mobile terminal systems. INDEX TERMS Ad-Hoc Networks, multifunctional antenna, mobile tablet, planar. I. INTRODUCTION
