A dual-band and dual-polarized fractal antenna for WLAN applications is presented in this paper. This design is based on the Sierpinski fractal antenna base station antennas. It is composed of two similar fractal antenna cross each composition. Antenna is composed of two different heights of the L-shaped feeder fed to achieve a dual polarization. The simulated and measured results show that the proposed...
