New design of T-type power divider network in microstrip technology for C-band downlink

This paper presents the design of a novel microstrip divider/combiner using T-type networks. Multiple step dividers were analyzed and designed, starting from the S-parameters representing the N-ports, their electrical specifications, and ending with full-wave simulations. We present here, two different designs with this technology, for 4 and 8 output ports. To validate the design, two prototypes working at C-band, were fabricated and tested. The insertion losses were 0.38 dB and 0.7 dB for the 4 and 8 output networks respectively, while the bandwidth obtained was 58% and 36% for the 4 and 8 output networks respectively.
