Abstract

This paper presents a novel one-to-eight compact feeding network based on the Wilkinson power divider for a circular antenna array. The network consists of four 1:2 conventional Wilkinson power dividers. The outputs revolve at 45 in order to satisfy the circular geometry on an FR-4 substrate. Moreover, the network size has been optimized and miniaturized targeting compact portable devices. The feeding network design targets WiFi and LTE/4G frequency bands. Designed and examined with the CST Microwave Studio, this feeding network provides suitable return loss, insertion loss and isolation parameters for the designated frequency ranges. Fabrication and measurement results closely correlate with simulation results. The design can be applied to SIMO and MIMO microwave systems.
