Mono-static radar cross section (RCS) is estimated for a set of randomly distributed loaded thin dipoles. The RCS calculation is performed using two techniques based on the total backscattered field and the radar equation. Different dipole configurations and complex load impedances are studied in order to highlight the RCS distortion. Numerical Electromagnetics Code (NEC) simulator is used for the computations.

This paper presents a novel low-cost and flexible passive RFID tag antenna for blood monitoring and tracking, which is in great demand by e-healthcare applications. The tag antenna consists of two compact symmetrical capacitive structures and works at the ultra-high frequency (UHF) European band (865 MHz-868 MHz). Measurement results show that the proposed design has a read range of 2.2 m, which is 4.4 times higher than commercial RFID tag antennas.
