E Band high gain antenna for 5G Backhauling Systems

An E band Cassegrain switched beam high gain antenna for 5G backhauling systems is proposed in this article. The targeted antenna is able to realize beam-switching operations and it is fed by a 7x7 array of Magneto-electric dipoles, with every element capable of providing a steering of +/- 0.33 degrees, through the beam switching operation. This antenna was thought to use beam switching for compensating small boom movements, which are estimated to be within +/- 1 degrees in both azimuth and elevation planes. The average gain within the band of interest is higher than 52 dBi. The proposed solution is based on a Cassegrain reflector fed through a feed array implemented by cavity-backed magneto-electric dipoles. This type of illuminator can be designed to have a gain and beam shape well suited for a feed array configuration thus being a valid alternative to classical feed array configurations based, for example, on horn antennas.
