In this paper, an isolation enhanced multiway power divider for wideband beamforming array is proposed. This method is based on the concept which converts the divider into multi-section stepped impedance transformer. In addition to this scheme, lumped inductors and capacitors are incorporated in isolation networks to enhance the isolation bandwidth of the divider. In/Output reflection and isolation...
A planar 4-way power divider with bandpass filtering response based on the coupled line is presented. Its frequency response is similar to a coupled line filter. Moreover, open stubs are utilized to get good frequency selectivity by introducing transmission zeros and improve input match. Three isolation resistors are used to satisfy both transmission and isolation property. The equivalent even- and...
