Noise suppression through a reactive surface for 60GHz radios

In today's 60 GHz radios large signal to noise ratios are needed due to the high atmospheric losses inherent to 60 GHz communications. This paper tackles the isolation of leakage noise from the transmitter to the receiver by means of a reactive surface. We achieved the aforementioned by using a variation of the artificial magnetic conductor (AMC) on a one layer liquid crystal polymer (LCP) substrate. It is proven that in order to achieve noise suppression the artificial material does not require a high-impedance surface.
