Abstract

A dual band F-shaped printed mono-pole antenna (USB dongle) with two meandered strips is proposed and tested. The two strips that resonating at 2.45 GHz and 5.2 GHz have uniform and fixed width of 0.5 mm. A thin layer of 0.8 mm thickness FR4 substrate (permittivity =4.4, loss tangent=0.0245) which is economically cheap is used for the unit fabrication.  The two resonant modes will best support Bluetooth (BT) and WLAN (Wireless Local Area Network) having enough supportive bandwidth which is defined by -10dB reflection coefficient. The proposed unit is low profile, compact and simple to fabricate. The whole unit that has an overall size of (0.8mm x 10 mm x 40 mm) is efficient for having 97% and 94 % total radiation efficiency at both operating frequencies respectively. Through applying different simulation scenarios to the unit such as varying the feeding location and changes in the strips length, it has been revealed that the antennas is sensitive and reactive. The proposed antenna has provided good performance and Omni-directional radiation pattern. Good matching between the simulated and measured reflection coefficient results for the antenna prototype has been achieved.

Keywords:

Low profile, Impedance band width, Radiation efficiency, Reflection coefficient.
