CPW-FED COMPACT SLOT ANTENNA FOR WLAN OPERATION IN A LAPTOP COMPUTER

摘要

A rectangular slot antenna fed by a coplanar waveguide is proposed for dual-band operations. The measured -10 dB bandwidth for return loss is from 2.05 to 2.65 GHz and 5.1 to 5.4 GHz, covering all the 2.4/5.2 GHz WLAN bands. A multi-feed 12-element planar array was designed and simulated. It shows that the features of small size, uniplanar structure, good radiation characteristics, and small mutual coupling are promising for multi-input multi-output applications in laptops.
