The proposed antenna has a simple planar structure and occupies area of 30 × 35 mm2 on the system circuit board of the portable communication devices. The simulated and measured octa-band monopole antenna frequencies cover the GSM850/900/1800/1900/DCS/PCS/UMTS and WLAN (2.4 GHz, 5.2 GHz and 5.8 GHz) band operations for S 11 ≤ – 10 dB. The measured peak gains are 3, 2.33, 5, and 3.3 dBi with sufficient bandwidths to cover modern portable communication devices. The simulated and measured results show a good agreement. This proposed antenna with multiband, broadband matched impedance, stable radiation patterns, constant antenna gains and compact size is suitable for multi-mode applications. |
