Abstract
Rotatable antenna (RA) represents a novel antenna architecture that enhances wireless communication system performance by independently or collectively adjusting each antenna's boresight/orientation. In this demonstration, we develop a prototype of radar sensing-aided rotatable antenna that integrates radar sensing with dynamic antenna orientation to enhance wireless communication performance while maintaining low hardware costs. The proposed prototype consists of a transmitter (TX) module and a receiver (RX) module, both of which employ universal software radio peripherals (USRPs) for transmitting and receiving signals. Specifically, the TX utilizes a laser radar to detect the RX's location and conveys the angle of arrival (AoA) information to its antenna servo, which enables the RA to align its boresight direction with the identified RX. Experimental results examine the effectiveness…
