Bandwidth enhancement for QMSIW antenna by using dual cavity and triangle slot [PDF]

International Journal of Electronics and Telecommunications
The miniaturization of substrate-integrated waveguide (SIW) antenna suffers from the narrow impedance bandwidth. It occurs on the quarter mode substrate integrated waveguide (QMSIW) antenna that has 75% miniaturization of the full mode SIW. This research

A SUBSTRATE INTEGRATED WAVEGUIDE TO SUBSTRATE INTEGRATED COAXIAL LINE TRANSITION

Progress In Electromagnetics Research C, 2013
In this paper, a novel substrate integrated waveguide (SIW) to substrate integrated coaxial line (SICL) transition using the 3dB SIW power divider (PD) and SIW 180 - phase shifter (PS) is proposed. The SIW-to-SICL transition realizes the easy integration of SIW, SICL, and active device in the same microwave communication system based on the substrate ...
