A Multi (U) Slotted Rectangular Micro-strip Multiband Patch Antenna
In this paper, the authors present a proposed design for rectangular micro-strip patch antenna by cutting U shaped slots in the rectangular patch which operates at two central frequencies 1.8, 2.7GHz. Which is a new dual frequency microstrip antenna? By micro strip feeding technique proposed antenna design they find the resultant return loss, VSWR and bandwidth. For the design of the microstrip antenna they have used FR-4 substrates which have permittivity of 4.4 and thickness 3.2, loss tangent is 0.02. They are using FEKO simulation software for designing and analysis.
