In this article, a novel design of multiband microstrip patch antenna has been presented for multiband applications. The Shirt shape antenna is designed on FR-4 substrate and is fed through 50 ohm microstrip feed line. Two l-shape slots are introduced in antenna for size reduction and to provide multiband characteristics while DGS (defected ground structure) is used to achieve bandwidth enhancement. The simulated results show that the antenna operates in three different frequency bands having resonance frequencies at 4.4GHz, 6.2GHz and 8.5GHz. The antenna exhibits good return loss of -21.1dB @4.4Ghz, -15dB @6.2GHz and -30.5dB @8.5GHz. The proposed antenna has stable radiation patterns and gain values which are 5.3db at 4.4GHz, 5.03dB at 6.2GHz, 5.27 at 8.5GHz. The VSWR is also less than 2 and has good efficiency values at the operating bands 62%, 89% and 93% respectively. The Shirt shape antenna finds its applications in commercial WLAN, Wi-MAX and in Radar application.
