In this work, a novel design of an implantable dipole rectenna with good efficiency is presented for wireless pacing applications. The proposed rectenna consisted of an elliptical-shaped printed dipole antenna, which used additional C-shaped structures to increase the inductance and achieve a resonance of 1.2 GHz. A separately designed full wave rectifier was tested and then integrated with the dipole...
In this paper, the interdigital structure is applied to the design of a miniaturized planar log-periodic antenna which is used in a TV broadcast wireless energy harvesting system. The lateral size of the printed antenna can be reduced approximately 35% while the overall performance characteristics is improved slightly. The simulated gain reaches 7.27dB at 515MHz and the measured −10-dB bandwidth is...
A wide-band 900 MHz to 2.45 GHz rectenna has been developed for Radio Frequency (RF) energy harvesting in the context of outdoors Wireless Sensor Nodes (WSN). Based on simulations of different rectifying circuits, the most appropriate one for low incident power levels has been manufactured and tested with a wide-band antenna. The theoretical analysis, confirmed by measurements, shows that the proposed...
This paper deals with an estimation of the impact of ultra wideband (UWB) pulses on printed-circuit-board (pcb) antennas for wireless communication systems using the 2.4 GHz ISM band (e.g. Bluetooth, WLAN or ZigBee). Measurements have been performed by using typical basic pcb antennas (e.g. monopole, dipole) which can be found in general literature. It is shown that the possible reached voltages at...
