A TWO-SLOT ARRAY ANTENNA ON A CONCENTRIC SECTORAL CYLINDRICAL CAVITY EXCITED BY A COUPLING SLOT

A Switched-beam Antenna Using Circumfere- Ntial-slots on a Concentric Sectoral Cylin- Drical Cavity Excited by Coupling Slots

This paper presents a switched-beam antenna using circumferential-slot on a concentric sectoral cylindrical cavity excited by coupling slots to operate at 5.8 GHz. The advantages of this antenna are conformal structure, high directivity and capable of switched-beam pattern in six directions. The antenna design starts from a single sector which is capable of switching between radiating and non-r...

Development of A Compact and Low Profile ‎Cavity Backed Slot Antenna Using Microstrip ‎Gap Waveguide Technology

Proof of concept of a cavity backed slot antenna based on inverted microstrip gap ‎waveguide (IMGW) technology is presented. Since the antenna is operating based on the ‎first resonating mode of the cavity, it is more compact compared to the ordinary cavity ‎backed slot antennas in which the second cavity mode is used for radiation. Furthermore, ‎the proposed antenna element introduces lower lo...

Reduction of Mutual Coupling between Cavity-Backed Slot Antenna Elements

Maintaining mutual coupling suppressing structure as simple as possible is becoming attractive in the electromagnetic and antenna community. A novel parasitic patch structure that can reduce mutual coupling between cavity-backed slot antenna elements is proposed and studied. The structure consists of only a simple rectangular patch inserted between the antenna elements, and it is therefore low ...
