Abstract
A CPW-fed dual-band monopole antenna loaded with dual-band artificial magnetic conductor (AMC) surface is presented for wireless local area network (WLAN: 2.4/5.2/5.8 GHz) and worldwide interoperability for microwave access (WiMAX: 2.5/5.5 GHz) bands. The proposed dual-band antenna consists of a tapered monopole antenna having two inverted L-shaped slots and has a size of 22 × 33 mm2: A 4 × 4 unit cell dual-band artificial magnetic conductor surface has been used as a reflector for antenna. The size of the antenna with AMC reflector is 68 × 68 mm2. The proposed antenna is fabricated and measured. Experimental result shows that the antenna operates form 2.1–2.87 GHz, 4.86–5.97 GHz which covers 2.4/5.2/5.8 GHz WLAN and 2.5/5.5 GHz WiMAX bands. It has a directional radiation pattern with peak gains of 6.64 dBi, 7.3 dBi and 6.2 dBi at 2.45 GHz, 5.2 GHz and 5.8 GHz respectively.
