Design of Broadband and Low profile Microstrip Patch Antenna using Strip Slot Hybrid Structure

Abstract

This study discussed the design and development of C-band Micro strip patch Antenna with Strip-Slot Hybrid Structure. The proposed antenna consisted of four strips which were separated by three narrow slots, ground plane with coupling aperture and Y-shaped feeding structure. The strip-slot feeding structure used to enhance the bandwidth up-to 41% by controlling the dimensions of the strips and the slots. The designed antenna was modelled in CST MW studio. The proposed antenna fabricated on FR-4 substrate with dielectric constant 4.4. The fabricated antenna was tested in the far-field antenna test range and Network Analyser. The test results were compared with simulated results. The proposed structure was good candidate for broadband data link and altimeter applications in airborne vehicles.
