ABSTRACT
This work presents the design and implementation of a beam steering transceiver prototype targeting narrowband IoT communications. The proposed architecture, integrating an open-source 8051 processor IP-core and a revised 4-channel DDS-PLL phase shifter, has been validated using an FPGA evaluation board, a custom PCB with four PLLs centered at 2.453-GHz and a custom frontend board for signal up- and down-conversion as well as actual transmission and reception through antennas.
