Abstract: In this paper a novel electrically small planar dipole antenna operating at 2.45 GHz is proposed. This antenna exhibits small dimensions of 11.2 X 5.1 X 1.575 mm3 (0.09 X 0.04 X 0.01 λ0 3 ) which is considered to be one of the smallest ever reported footprints at this operating frequency. It has a simulated realized gain of 1.17 dBi along with an estimated efficiency of 87.4%. Due to the fact that ESAs are not self-resonant by nature, an impedance matching network has to be utilized to tune the antenna to resonate at the desired operating frequency. Three different matching approaches are studied in this paper. Finally, the antenna is modelled using the infinitesimal dipole model.
