A novel 1#x2236;19 microstrip radial power divider design for the application in antenna array

摘要

A novel microstrip radial 1∶19 power divider is proposed in this paper. The conventional impedance transformation method is used here with a single substrate to realize 1 to 19 power transmission. To verify our design, the power divider is fabricated and tested. It can be observed that it achieves 29.4% impedance bandwidth (VSWR<2), the transmitted magnitude and phase imbalance for 19 outputs are ±0.1dB and ±1deg, respectively.
