Abstract: This paper presents the design and development of U-slot, open stubs microstripline feed partial ground plane rectangular microstrip antenna for broadband wireless communication applications. By inserting U-slot of dimension 0.625 cm the antenna gives a bandwidth of 92.6% with a virtual size reduction of 38.88% with gain of 4.19 dB. However this 92.6% of bandwidth can be enhanced to 138% again by placing two stubs simultaneously on left and right side of microstripline without effecting the gain and virtual size reduction. The antennas are designed on low cost modify epoxy substrate material of dielectric constant er = 4.2 and h = 0.16 cm at 3 GHz. The antennas are use full for WiMAX, LAN, Bluetooth and IEEE 802.11a application
