Split ring resonator-based left-handed coplanar waveguide
In this letter, a planar left-handed propagating medium consisting of a coplanar waveguide (CPW) inductively coupled to split ring resonators (SRR) and periodically loaded with narrow metallic wires is proposed. The wires ... -
Towards a traceability system based on RFID technology to check the content of pallets within electronic devices supply chain
In the last few years there has been a growing interest in smart solutions capable of dealing with the traceability of products and materials to improve logistical processes. Most of the existing solutions have been ... -
Ultra-wideband metamaterial filter based on electroinductive-wave coupling between microstrips
In this work, we analyse the frequency response of microstrip lines coupled by complementary split ring resonators (CSRRs) etched on the ground plane supporting electroinductive waves (EIWs). The single-particle ... -
Wideband printed monopole antenna for application in wireless communication systems
Empirical results of an electrically small printed monopole antenna are described with a fractional bandwidth of 185% (115 MHz to 2.90 GHz) for return-loss better than 10 dB, peak gain and radiation efficiency at 1.45 GHz ... -
Zigbee radio channel analysis in a complex vehicular environment [wireless corner]
In this paper, the influence of topology and morphology of a particularly complex scenario for the deployment of ZigBee wireless sensor networks is analyzed. This complex scenario is a car. The existence of loss mechanisms ...
