碩士 === 南台科技大學 === 電子工程系 === 95 === Novel designs of CPW-fed monopole antenna were proposed in this thesis. At first, we proposed a printed monopole antenna for broadband operation. Then, we investigate the effects of printed wide-band monopole antenna etched slits on the metal surface, the current distribution concentrate on the edge of the slits to suppress the undesired frequency-band. The considered operating bands include the WLAN band and WiMAX band. In this paper, we proposed the design methods for the band-reject function; several antenna designs capable of single-band rejected and dual-band rejected are also detailed investigated. The proposed antennas are suitable for the antenna using band-rejected method to suppress dispensable frequency-band to design multi-band antennas for WLAN/WiMAX operation.
