abstract

  • A periodic nonreciprocal leaky wave antenna is presented based on coupled microstrip lines on a ferrite substrate. This printed layout was validated to exhibit nonreciprocal transmission properties in its guided-wave region (β>k0). To accomplish radiation, the printed dual transmission lines are operated in the fast wave region (β0), where strong spectral asymmetry (ω(K)ω(2π-K)) is also observed. This leads to novel nonreciprocal radiation characteristics. Specifically, more than 10 dB difference is observed between the simulated transmit and receive gain in the E-plane. The antenna can be also magnetically scanned between 20° and 90° (endfire) in the elevation plane by changing the external magnetic field strength. The associated gain varies between 8.34dB and 9.95dB at the operating frequency 2.8 GHz as the beam is scanned. © 2012 IEEE.
