Abstract

This paper reports a novel wideband two-way power divider with improved out-of-band rejection based on substrate integrated waveguide (SIW) technology. Periodic radial line slots are etched on the bottom side of SIW to achieve the band-stop characteristic. The band-pass response is achieved by combing the band-stop characteristic of the radial line slots and the high-pass characteristic of SIW. An experimental circuit is fabricated by the traditional printed circuit board technology. The measured results show that the power divider has the advantages of wideband (about 42.8% with center frequency 7 GHz for Return Loss > 10 dB) and sharp roll-off skirts (better than 37 dB/GHz).
