Artificial Magnetic Conductor-backed Dual Band Antenna for Wireless Applications

摘要

A novel compact dual band antenna with Artificial Magnetic Conductor (AMC) backed ground plane is proposed for small form factor gadgets. The antenna is designed to cover two wireless network bands at 2.4 GHz and 5.5 GHz. The antenna has an overall dimension of 20 x 14 x 1.6 mm^{3. The AMC structure consists of 4 x 4 first order fractal unit cells that are made up of two concentric square ring slots. The AMC ground plane improves the antenna gain by 2.61 dBi due to the suppression of surface wave.}
