Abstract
A new broadband 180° hybrid ring coupler
with a Chebyshev return loss response, implemented in
microstrip line, and a phase inverter using microstripto-
slotline transitions, is presented. The transitions were
constructed using via short circuits and optimized radial
slot stubs. The manufactured prototype was found to
operate over a 118% bandwidth in the frequency range
0.72-2.8 GHz.
