Abstract: A 9 Slotsdual band microstrippatch antenna is presented in this paper .The antenna resonates at 5.27 GHz and 7.61 GHz frequencies. The antenna is fed with coaxial feed giving bandwidths of 11.87%& 11.22%and VSWR of the both bands is less than 1.09.Theproposed antenna can be used for WLAN (Wireless Local Area Networks) applications.
