Design of Miniaturized Planar Inverted F Antenna

This paper presents a PIFA- Planar Inverted F-Antenna at 2.45GHz. The 2.45 GHz band needs a miniature Planar inverted F antenna, which is the aim of the project. ensuring that., when coupled to a 50-ohm source without an additional feeding circuit, the proposed antenna has a VSWR of less than 2 over the 2.4 GHz ISM band. The design is simulated using HFSS and also the PCB Antenna designer application in MATLAB 2021b. The proposed antenna is finally fabricated and shows a good Gain and the measured results are closely matching with simulated results and are satisfactory for the design frequency. For further evaluation, the same design is simulated using Another EM simulation tool and the results are validated.
