In this paper, two novel wideband planar power divider/combiners are presented. The first one is based on Y-shaped half mode substrate integrated waveguide (HMSIW) and its wideband performance is obtained by directly matched to tapered microstrip line. The second one is derived from oversized microstrip taper and two-layer four-way power divider/combiner is also designed. Simulated results show that...
In this paper, a novel microwave planar integration scheme is proposed based on SIW technology. All the passive components in RF transceiver are implemented using SIW, including antenna, duplexer, TX/RX filters and LO power divider. A demonstration X-band transceiver is designed in a single layer printed circuit board. The design of SIW components and RF/IF circuits are discussed, as well as various...
In this paper, a half mode substrate integrated waveguide (HMSIW) mixer at Ka-band is proposed. A newly developed 3-dB cruciform HMSIW coupler was employed to add LO and RF signal on schottky diodes. Size of the mixer is more compact than traditional narrow-wall aperture coupling SIW or HMSIW configuration mixer. The mixer was designed and fabricated on Roggers 5880 substrate with beam lead schottky...
