Abstract-This paper presents a design of microstrip transmitting and receiving antennas to be used for time reversal ultra-wideband imaging applications. The transmitter and receiver arrays are together known as a time reversal mirror (TRM). Based on the properties of time reversal and its imaging applications, an antipodal Vivaldi antenna and a monopole antenna are proposed for the transmitter and receiver designs, respectively. Simulation and measurement results demonstrate the efficiency of the antennas for a time reversal mirror. The overall system is demonstrated for source and target imaging applications.

“…10(c). The antenna dispersion can be analyzed from its analytic impulse response, which is calculated by the Hilbert transform H of s(t), given by h + (t) [6]. The envelope |h + (t)| localizes the energy distribution versus time and thus measures the dispersion of an antenna.…”

“…It can be analytically expressedassuming that both characteristic transmit and receive antenna impedances are equal-as [12]: (2) where p stands for each possible path and u(t) is the transmitted signal (1). h tx,p and h rx,p are vectors representing the transfer functions of the antennas at the direction defined by path p, and h ch is a matrix representing the transfer functions of the channel at the path p.…”

Communications are becoming the bottleneck in the performance of Chip Multiprocessor (CMP). To address this issue, the use of wireless communications within a chip has been proposed, since they offer a low latency among nodes and high reconfigurability. The chip scenario has the particularity that is static, and the multipath can be known a priori. Within this context, we propose in this paper a simple yet very efficient modulation technique, based on Impulse Radio -On-Off-Keying (IR-OOK), which significantly optimizes the performance in Wireless Network-on-Chip (WNoC) as well as off-chip scenarios. This technique is based on interspersing information pulses among the reflected pulses in order to reduce the time between pulses, thus increasing the data rate. We prove that the final data rate can be considerably increased without increasing the hardware complexity of the transceiver.

Abstract-In the paper, the unified design procedure for planar dipoles oriented on UWB application is proposed. The procedure leads to obtain a good matching characteristic of planar dipoles in UWB frequency band. The design process is split into two parts: the radiator and the balun design. The Radiator Quality Factor (RQF) is defined as an evaluation suitability of planar radiators to be matched in UWB frequency band. Based on RQF, the optimal circular radiator is chosen, and the whole dipole antenna is designed. The general algorithm of antenna design is formulated and utilised in the planar dipole with elliptical arms project. Two antennas, with circular and elliptical arms, have been fabricated and measured in order to verify the design procedure. Both antennas are characterized by the reflection coefficient less than −10 dB from 2 GHz up to 14 GHz.
