In this communication, the self-interference (SI) channel and the novel enabling techniques for a compact inband full-duplex relay are described and characterized in different operating environments. The full-duplex operation is based on a novel antenna design that uses wavetraps to provide passive isolation of up to 70 dB between the transmit and receive antenna ports. The passive isolation is complemented...
This paper presents an analysis of three types of antennas for backscatter radio reader and a method for measuring backscattering signal from antennas which involves using a network analyzer connected to an anechoic chamber with and without the receiving antenna. We analyzed the backscattered signals of two types of dipole: wire dipole at the operating frequency 1.8 GHz and microstrip dipole operating...
