Abstract
This article introduces a wirelessly powered phased-
array transceiver for fifth-generation (5G) relay systems. To real-
ize the battery-less relay operation, 24-GHz wireless power
transfer (WPT) is employed. This relay transceiver consists of
the proposed vector-summing back scatter for Transmitter (Tx)
and a passive phase-shifting self-heterodyne Receiver (Rx) with
a rectifier for Rx and WPT. The receiver generates dc power
from the 24-GHz WPT signal, which is also used as a local
oscillator (LO
