Abstract

A very-low-profile grounded coplanar waveguide (GCPW)-fed slot antenna with an antenna thickness of 0.8 mm(about 0.0064λ at 2.4 GHz) and a compact size of 15 mm x 40 mm(about 0.12 λ x 0.32 λ at 2400 MHz) for 2.4/5.8 GHz dual-band wireless local area network (WLAN) on-body antenna application is presented. The GCPW slot antenna consists of a top ground with the GCPW feed line and radiating slot embedded thereon and a bottom ground spaced 0.8 mm to the top ground. The radiating slot is an asymmetric T-shape slot having a longer slot path for 2400~2500 MHz band and a shorter slot path for 5725~5875 MHz band. It is convenient to tune the dual-band operation by adjusting the lengths of the longer and shorter slot paths, respectively. Additionally, owing to the presence of the bottom ground, the GCPW slot antenna has decreased backward radiation. This causes antenna’s impedance matching very slightly varied when it is in the proximity of human body. The very-low-profile GCPW slot antenna is presented.
