Since substrate integrated waveguide (SIW) is not directly compatible with active circuits, additional transitions to planar transmission lines are indispensable. In this letter, a novel hybrid SIW-CPW structure coupler applying an antenna feeding network is presented. SIW is used as the radiating portion while coplanar waveguide (CPW) is the input matching portion that is connected directly to the...
A novel substrate integrated waveguide (SIW) slot antenna array is proposed in this paper. The array, based on SIW scheme, consists of one compact SIW 4-way power divider and 4 radiating SIWs each supporting 4 radiating slots. The 4-way power divider uses the self-compensating phase shift technique, which can make the feeding network operate over a broadband. Comparing with conventional SIW slot antenna...
The transmission property of power line channel has been analyzed, and power line spread spectrum communication has been expounded in the paper. We study a complementary network system which works simultaneously two communication systems, wireless (IEEE 802.15.4 Zigbee) and wired (Power line carrier communication; PLC) communication. Our analyze results show that the communication result of the table...
