A Novel Two-Layer Low-Profile 23-GHz Microstrip Array Fed by Slots in an SIW for Wireless Backhauling Applications

This paper proposes a robust option for developing a new class of efficient and cheap antenna array based on patch array fed by substrate-integrated waveguide (SIW) through slot apertures for wireless backhauling applications. It consists in performing the feed network in SIW and the radiating structure in microstrip technology. The microstrip lines are coupled to the slots on the top wall of the ...
