Abstract

In this paper, a novel planar inverted-F antenna (PIFA) using meander conductor lines directly coated on the edge of the rectangular FR-4 substrate of size 80/spl times/42/spl times/1.6 mm and relative permittivity /spl epsi//sub r/=4.7 is presented. The FR-4 substrate is very cheap and widely available. The meander line PIFA has been designed based on a vast amount of parameter study, using a high frequency structure simulator (Microwave studio). The proposed antenna has the nice features of a dual frequency antenna. The simulation results also show that the performance of the proposed antenna does not depend on ground size. Despite the proposed simple structure, which can be realized quite easily and cheaply, the performance of the designed and fabricated antenna is better than those commercially available at present.
