The latest technology is demanding the miniaturized size of the antenna with wider bandwidth to allow the higher data rates. Fractal antenna with miniaturization in antenna size and enhancement in bandwidth is given in this paper. A line feed hexagonal fractal antenna and an inset fed Minkowski fractal antenna operating at 2.4 GHz Wireless LAN application (WLAN) with improvement in the bandwidth from 14.58% to 112.5% in case of the hexagonal fractal antenna. An issue with the fractal antenna is choosing a feed location which can be solved using complementary structures is also illustrated in this paper.
