Abstract :
In this paper, a wideband log periodic dipole antenna (LPDA) with small size is proposed. The arms of the dipole are in the shape of a second order fractal, which makes each dipole element to resonate in more than one frequency. This results in a LPDA antenna whose size can be greatly reduced. The proposed antenna has a substrate size of 90 × 60 mm2 and operates over 2-8 GHz bandwidth with VSWR<; 2. The antenna has stable pattern over the frequency range.
