A (L) Slotted Rectangular Micro-Strip Multiband Patch Antenna
In this paper, the authors present a proposed design for Rectangular micro-strip patch antenna by cutting L shaped slots in the Rectangular patch which operates at four central frequencies 1.75,2.1,2.85,3.49GHz Which is a new multi-frequency micro-strip antenna. Using proposed antenna design and micro strip feeding at proper position they find the resultant return loss, VSWR and bandwidth. For the design of the micro-strip antenna they have used FR-4 substrate which has permittivity of 4.4 and thickness 3.2,loss tangent is 0.02. They are using FEKO simulation software for designing and analysis. They have observed that using slotted patch antenna and using micro strip at proper location they can get better return loss, VSWR bandwidth and multiband.
