Summary:Wireless local area network (WLAN) applications nowadays has become more popular especially those operating in the 2.4 GHz ISM band. There are a lot of efforts on combining the WLAN, a/b/g bands together. Such new designs either provide inadequate coverage of the frequency band or not suitable for integration in some portable devices. This paper describes the design of the triangular and circular dual band microstrip antenna using scaling factor and inset feed technique. The antennas were designed to operate in the indoor WLAN ISM band at 2.4 GHz and 5.2 GHz. The scaling factor of 1.05 has been chosen for the design starting from the lowest resonating frequency at each band. The antennas have been fabricated on the FR4 photoboard with epsiv r = 4.7, substrate height of 1.6 mm and tan delta = 0.019 using the wet etching technique
