Abstract

This paper presents the design of thin planar one-sided directional slot antenna on patterned circuit board. Our proposed planar antenna has the matching circuit composed of coplanar waveguide (CPW) transmission line, interdigital gap, a top metal layer and a bottom floating metal layer. In order to realize the one-sided directional properties, the length of the top metal layer is adjusted, and at that time, the bottom metal layer is adjusted to the length that doesn´t resonate. The final antenna size of the 300 MHz specified low power wireless receiver is 137 mm Ã— 61 mm. We also fabricated the one-sided directional slot antenna using FR4, and measured the radiation pattern.
