To overcome this limitation, a planar single-reversal permanent magnet focusing system is proposed for a narrow-separation three-beam array. The impact of magnetic field drop in the reverse region on ...

In this paper, the dual-band retrodirective reflector array using Substrate Integrated Waveguide (SIW) and inkjet-printed technologies on paper, for operability around 3.6 GHz and 5.8 GHz is proposed.
