Abstract

The demand of smaller and compact antennas in modern mobile and wireless communication system has been increasing. Because of low cost and process simplicity, printed monopole antennas are popular candidates for these applications and applicable in body centric communications. A simple and compact microstrip-fed printed monopole antenna is proposed in this design. The antenna is composed of a rectangular ring for operating frequency at 2.45 GHz. The con?guration has rectangular base with rectangular slot cut inside the patch resulting the rectangular ring. The dimension of the patch is 12 mm × 26 mm with ring width size of 1 mm along the patch. The size of partial ground plane is 20 mm × 9 mm while the dimension of substrate used is 20 mm × 40 mm. The antenna are fabricated of FR4 substrate with thickness of 1.6 mm, dielectric permittivity, is 4.7 and tangent loss is 0.019. The designed antenna had bees successfully simulated using CST Microwave Studio. It was found that the antenna operates well at 2.45 GHz. Return Loss measurement had been done using network analyzer and both simulated and measured results are in good agreement. The antenna covers bandwidth from 2.35 GHz to 2.8 GHz which is 17.54%.
