Abstract

A kind of novel multiband monopole antenna with square-nested fractal is proposed and designed, which is nested with a series of similar square elements. The antennas can synchronously operate in multiple frequencies, covering the four required frequencies, 2.4GHz/3.5GHz/5.2GHz/5.8GHz, for WLAN/WiMAX application. The antenna surface currents are simulated by CST Microwave Studio®, a 3-dimension full-wave electromagnetic simulator, and the multiband operating mechanism has been explained from analysis of the simulated results. Then model of the proposed monopole antenna fed by coplanar waveguide has been obtained. Finally, prototype of the antenna has been manufactured and measured in anechoic chamber. The results well match the simulated, which verify the feasibility of design idea. Moreover, these antennas are miniature and the design idea can be easily applied into other types of nested structure, the features of which make the proposed antenna has promising application in multiband fields.
