ABSTRACT:
Nowadays, wireless systems require compact multi band antennas that can
dynamically change some of its fundamental parameters such as frequency
band, polarization and radiation pattern. The novelty of the proposed work
lies in using two conducting strips that are perpendicular to each other. The
longer strip resonates at 2.4 GHz and the shorter strip resonates at 3.5 GHz.
The length and width of the Ground plane is made equal to length of the main
arm and length of the side arm respectively. The results are obtained by simulating
the antenna structure using simulation tool Ansoft HFSS v15.0. The
Simulated antenna Gains were 6.2364 dBi and 7.1758 dBi for frequencies of
2.4 GHz and 3.5 GHz respectively. The antenna dimensions are 50 × 25 × 1.6
mm3 on a 1.6 mm thick FR-4 substrate.
