Abstract
A cost-effective transmit-array (TA) antenna
design framework is presented and experimentally validated for
5G backhaul applications at the WiGiG band. The antenna is
composed of a discrete dielectric lens (DDL) fed by a horn,
specifically designed for this application. Both the TA and feed
are fabricated using additive manufacturing. Metal coating and
Fuse Deposition Modeling (FDM) are employed for the horn
and TA fabrication, respectively. Simple design rules are
devised to quantify the bandwidth of this type of antennas as
function of the aperture dimension ࡰ and focal distance ࡲ .
Based on this framework a compact TA antenna (ࡲ ࡰ ( . = ⁄
than can comply with typical specifications for 5G backhaul
links at WiGiG band (minimum gain of 30 dBi from 57 to 66
GHz) is designed.
