“…The results demonstrate that the receiving antenna signal is less distorted compared with the input signal. Effect of the antenna in signal transmission can be analyzed [8] by considering the envelope of the transient response. The peak output voltage from an incident waveform depends on peak value “ P ” and given in Eq.…”

A compact two‐element diversity planar antenna for ultra‐wideband (UWB) application with band‐notch function is proposed. By adapting two symmetrical rectangular patches with three bevels cutting in the edge of the radiators, the antenna provides wideband impedance matching characteristics over the desired frequency range. The wideband isolation can be achieved through uniform branch length ratio used in the ground plane. Measured S‐parameters show that the antenna is able to cover the entire UWB band from 3.1–10.6 GHz and good isolation of less than ‐25 dB. Also it has a band‐notch function to avoid overlap with the 3.5 GHz WiMAX band. The radiation pattern, realized gain, envelope correlation, and pulse handling capacity are measured. From the results, it is observed that the proposed diversity antenna can be suitable for UWB application. © 2012 Wiley Periodicals, Inc.

“…The receiver side is composed by a receive antenna, a matched filter, a sampling device and a demodulator module, which permits to recover the transmitted information data. Let p(t) be the pulse at the output of the pulse generator, h F (t) the impulse response of the transmit filter [4] and h A (t,θ,ψ) the impulse response of the transmit antenna [5]. The angular dependence (θ,ψ) of the antenna impulse response is included [6].…”

In this paper a complete analysis of the non-idealities in Ultra Wideband (UWB) systems is presented, from both a component point of view and a system point of view. The behaviour of a realistic UWB transmission scenario is investigated with both simulations and measurements of fabricated components. I. INTRODUCTIONUltra Wideband (UWB) is a wireless technology, whose usage of a very huge bandwidth permits to achieve many advantages for different applications: for example, high data rate for communication applications, high resolution for Radar and localization purposes … [1].Since the allocation of a frequency band for UWB purposes in US [2] and in Europe [3], many contributions of UWB components have been presented in literature: antennas, filters, RF-front end… [1]. Moreover, also many system aspects (such as bit-error-rate (BER), signal-to-noise ratio (SNR), …) of the UWB transmission have been assessed.One crucial aspect in UWB systems is the non-idealities of the system itself. The non-idealities provoke a worsening of the transmission and hence a changing of the system performance w.r.t. the ideally expected one. Hence, the investigation of the impact of the non-idealities on the system performance is an important task. Moreover, having a quantification of these non-idealities permits to introduce correction strategies.The aim of this paper is to investigate the non-idealities in the RF-front end and to quantify their impact on the signal transmission. The paper concentrates on a communication point of view. A similar, dedicated analysis could be extended also to Radar scenarios.The paper is organized as follows: in the next section the UWB transmission is presented, deriving the UWB radio link equation for impulse radio transmissions and highlighting the non-idealities of each component of the UWB transmission system. In Section III the non-idealities of the presented UWB scenario are investigated. Finally, in the last section the impact of these non-idealities on a realistic UWB communication scenario is assessed, calculating the worsening of the BER when real component are consider w.r.t. the case of an ideal system.

In this paper the problem of the spectrum optimization in Ultra Wideband systems is investigated. A UWB system based method by which the transmit signal fits optimal to the given mask, is presented. According to this method, a particular filter structure is designed, which allows for compensating the nonideal behavior of the pulse generator and the antenna of the UWB transmitter. Using the proposed method, a filter has been designed and fabricated for a particular antenna and pulse generator. For verification, measurement results are presented.
