Description
Summary:The design of multiband antenna plays a vital role and enhances the functionality of mobile equipment for various wireless services over the last decade. This paper presents a sophisticated quad-band fractal microstrip patch circular monopole antenna with a star shaped slot. The proposed structure is iterated two times to have a Kagome crest fractal antenna. In the paper, optimization of quad band antenna using the Quasi newton Optimizer (QNO) is also presented. Optimizing various design parameters for the proposed antenna in HFSS is simulated. The antenna dimensions are 100mmx100mmx1.6mm occupying an area of 100cm2. Model simulation and experimental validation is done for three frequency ranges, 2.8-3.5GHz, 4.8-7.5GHz and 8.1-9.4GHz, resonating at 3.1GHz, 5.2GHz, 6.8GHz and 8.7GHz respectively. The proposed antenna operates for several wireless applications including RF Energy harvesting, dedicated short range communication, Satellite communication, wireless power transfer to a micro aerial vehicle, etc. can be covered with these band of frequencies. VSWR, return loss, radiation pattern, gain is some of the parameters considered to prove the performance of the fabricated design prototype.
