Summary:
Wireless local area network (WLAN) applications nowadays has become more popular especially those operating in the 2.4 GHz ISM band. Nowadays, there are a lot of efforts on combining the WLAN, a/b/g bands together. Research on dual band and multiband antennas has gone tremendous development throughout the century. This paper describes the design of the dual band microstrip antenna using scaling factor technique and inset feed with the integration of active devices. The antennas were designed to operate in the indoor WLAN ISM band at 2.4 GHz and 5.2 GHz. The dimensions of each single element of the microstrip antenna, at these operating frequencies were calculated using transmission line model and their individual S-parameter data. The scaling factor of 1.05 has been chosen for the design. The antennas have been fabricated on the FR4 microstrip board with εr = 4.7, substrate thickness of 1.6 mm and tan δ = 0.019 and proved to be operating with adequate bandwidth and radiation characteristics.
