Ultra-high gain transmitarray antenna for wireless backhauling at 280 GHz

Abstract

An ultra-high gain transmitarray antenna for pointto-point backhaul links at 280 GHz is presented here. The proposed array exhibits a 3-bit phase resolution, comprising only three metal layers and no metallized vias. Thanks to a dedicated synthesis procedure, the unit-cells achieve very low losses, full phase coverage and are compatible with a standard printed circuit board process. A 140×140-element transmitarray is numerically optimized and experimentally characterized, using a 10 dBi horn as a feed. A peak gain of 44.5 dBi with 52.3% aperture efficiency and 0.9° half-power beamwidth are reported at the center frequency.
