Abstract
An application specific tri-band hexagonal microstrip antenna with saw tooth shaped defected ground structure (DGS) is proposed. In this paper, a hexagonal microstrip antenna is designed for 5.2 GHz which is basically WLAN band (5.15–5.35 GHz). Now in this structure two defects are suitably incorporated and the positions are so optimized that two additional frequency bands 2.4 GHz, i.e. the Bluetooth band (2.4–2.48 GHz) and 5.8 GHz, i.e. the second WLAN band (5.725–5.825 GHz) are obtained. The fabricated prototype of the proposed antenna occupies an area 35 mm X 27.4 mm. Therefore, the structure has the characteristics of application specific multi band resonance. The variation of different parameters of the microstrip antenna is extensively studied. The proposed multiband microstrip antenna is functional simultaneously at three specific application band frequencies with approximately 84% surface area reduction for the largest patch dimension corresponding to 2.4 GHz.
