   In order to curtail mutual coupling between two closely spaced microstrip monopole antennas operating at frequencies 28 GHz and 39 GHz, the concept of electromagnetic cloaking is applied by utilizing elliptical metasurfaces. In this paper, we show that by enveloping the monopole antennas with the specifically engineered metasurface cloaks, not only is there a significant reduction in the mutual electromagnetic interaction but also restoration in the radiation patterns are observed, as if the antennas were completely isolated from each other. The decoupling effect is seen in the reduction of mutual S-parameters. This enables the antennas to radiate independently even though they are placed in a very close proximity.

   Abstract: With the relatively recent realization that millimeter wave frequencies are viable for mobile communications, extensive measurements and research have been conducted on frequencies from 0.5 to 100 GHz, and several global wireless standard bodies have proposed channel models for frequencies below 100 GHz. Presently, little is known about the radio channel above 100 GHz where there are much wider unused bandwidth slots available. This paper summarizes wireless communication research and activities above 100 GHz, overviews the results of previously published propagation measurements at D-band (110-170 GHz), provides the design of a 140 GHz wideband channel sounder system, and proposes indoor wideband propagation measurements and penetration measurements for common materials at 140 GHz which were not previously investigated.
