On-body UWB MIMO antenna for UWB application
2013 Asia-Pacific Microwave Conference Proceedings (APMC), 2013In this paper, a UWB MIMO antenna for an on-body application is proposed and antenna performance with body effect and the impact on the human body are investigated. The proposed MIMO antenna is composed of an UWB antenna above ground plane and an additional isolator located between the two antennas to enhance the isolation characteristic.

Detecting UWB Radar signals with UWB communication interference
2014 IEEE Military Communications Conference, 2014Ultra wideband (UWB) technology has been widely researched for both radar and communication systems. However, detecting the presence of a signal is essential and challenging for many applications. In this paper, we propose a novel detector for UWB radar signals with UWB communication interference by exploiting the signal cyclic features. A single-cycle

High-precision UWB-based timestamping
2011 IEEE International Symposium on Precision Clock Synchronization for Measurement, Control and Communication, 2011The work presented in this paper is related with time synchronization for wireless networks. In particular, it is focused on the proposal and experimental evaluation of a low-cost and high precision timestamping technique based on Ultra Wide Band (UWB) signalling. In recent years, the use of such systems has gained an increasing success thanks to their

Low complexity impulse radio based UWB (IR-UWB) transceiver
2007 IEEE Antennas and Propagation Society International Symposium, 2007In this paper, a RF transceiver for low complexity impulse-radio-based UWB system is presented. The proposed transceiver is based on noncoherent receiver and OOK modulation. The transmitter consists of a CMOS impulse generator chip of low power consumption, and a planar UWB filter.

A PA for MBOFDM-UWB and IR-UWB transmitters
2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS), 2015This paper describes the design of 4.2 to 5.9 GHz CMOS power amplifier (PA) for applications in ultra-wideband (UWB) commuincations. The PA operates in the linear region over the input range of −12 dBm and delivers an output power of 6 dBm. The post layout simulations indicate the power added efficiency (PAE) is more than 35% at 5 GHz frequency and ...
