In this paper, the complementary split ring resonator (CSRR) is studied and applied to design a printed ultra wideband (UWB) antenna with dual band-notched characteristics. Dual band-notched function is obtained by incorporating the CSRR in the radiating ... see more

Synchronization is an important issue in multi hops Wireless Sensor Networks (WSN). Such networks are known by their limited resources of energy, storage, computation, and bandwidth. In addition if the networks entities are deployed with high density, it ... see more

A new small circular patch antenna for ultra-wideband (UWB) applications is presented. By studying this structure, it is shown that the insertion of a slot with the desired length and width in the ground plane, can lead to a large bandwidth. Our antenna, ... see more

In this paper the new design of UWB inscribed slotted circular disc monopole antenna  is used in the detection of brain cancer is presented. The proposed antenna design  consists of circular patch and the bandwidth is increased to cover the UW... see more

In this paper, we have proposed an analytical body (breast-tissue) propagation model in terms of scattering parameters towards the design goal of a suitable ultra-wide band, (UWB) transceiver for early breast tumor detection. The scattering parameters are... see more

The paper addresses ultra-wideband (UWB) channel estimation and line-of-sight (LOS) vs. non-line-of-sight classification based on the  application of the unscented Kalman filter (UKF) and the analysis of the multipath channel response characteristics... see more

The potential of multi-sensor fusion for indoor positioning has attracted substantial attention. A ZUPT/UWB data fusion algorithm based on graph optimization is proposed in this paper and is compared with the traditional fusion algorithms, which are based... see more
