Abstract

This letter introduces a new method of achieving broad VSWR bandwidth and axial ratio bandwidth (ARBW) deploying fractal geometry in a single feed compact annular slot antenna loaded with diagonal slots. Various studies have been carried out for different iteration order (IO) and iteration factor (IF) on antenna performance. A measured VSWR bandwidth (2:1) of 400 MHz (1.37 GHz to 1.77 GHz) and measured ARBW of 360 MHz (1.47 GHz to 1.83 GHz) is achieved. A measured peak gain of 6.6 dB is reported at 1.775 GHz. This antenna can be applied to handheld devices applications and WSN node positioning requiring GPS Data.
