Abstract: A multi-branch printed antenna is designed in this paper, which consists of three L-shape units, corresponding frequencies of 2.4 GHz,3.5 GHz and 5.4 GHz. It can be applied to WLAN and Wi MAX systems. Microstrip line is designed as T-shape to feed the antenna and match each radiation unit. The electromagnetic simulation software HFSS is used to design the antenna. The result shows that 10 d B impedance bandwidths are approximately 1 GHz(4.9-5.9 GHz) and 310 MHz(2.24-2.55 GHz) for WLAN, and 380 MHz(3.3-3.68 GHz) for Wi MAX. The designed antenna is fabricated and then tested. Good performance is obtained for far-field characteristics of radiation. The total gain of this antenna is between 2.5 and 4.7 d Bi.
