A Novel Double U-Slot Microstrip Patch Antenna Design for Low-Profile and Broad Bandwidth Applications

A low-profile double U-slot microstrip patch antenna with a wide operating bandwidth has been developed in this article. This design produces the dual radiative resonant modes adjacent to each even at the thickness of the antenna of $0.02 {\lambda _{0}}$ . An extremely stable radiation gain that varied from 6.2 to 6.8 dBi is a...
