Abstract:

A novel ultra-wide band (UWB) printed antenna with a semi-circular metal patch and a wing-shaped metal ground plate is presented. The proposed planar antenna has an ultra-wide band and small size. It has a simple structure, therefore is easy to fabricate. Its measured -10 dB return loss bandwidth covers a frequency range between 3.6 GHz and 11.0 GHz. In other words, the ratio impedance bandwidth reaches 3∶1. This type of antenna is suitable for short-distance UWB communications.

Key words: CPW, UWB, printed antenna
