Design of a Retrodirective Array Antenna for Microwave Power Transmission in Terrestrial Backhaul Links

A Retrodirective array (RDA) is an array of antennas designed to receive signals from a specific direction and retransmit another signal back in the opposite direction. This property is useful in backhaul networks, where communication links need to be established between base stations. Microwave Power Transmission (MPT) involves the transmission of power wirelessly using microwaves with applications, such as powering remote equipment or sensors. In this work we have redesigned an RDA antenna using CST Studio suite software, allowing for the creation of a system with novel functionalities such as improved antenna performance and signal steering. This antenna design is capable of transmitting power efficiently using the phased array method. This system can be deployed in powering terrestrial backhaul links in cellular networks located in rural areas.
