Flexible Wideband Microstrip-Slotline-Microstrip Power Divider and its Application to Antenna Array

IEEE Access, 2019
In the satellite microwave power transmission (MPT) system, antenna arrays are usually adopted for a higher gain. For the passive wideband antenna array, wideband power dividers are essential when the feed network is constructed.
