碩士 === 國防大學理工學院 === 電子工程碩士班 === 99 === ABSTRACT
Two L-shaped printed slot antennas of broadband and dual-band circular- polarization operations are proposed in this thesis. The main features of the broad band circular polarized (CP) printed slot antenna are an L-shaped slot and a pair of inverted L-shaped corner slits. In this design, a higher CP frequency band created by a pair of inverted L-shaped corner slits and a lower CP frequency band created by a pair of inverted L-shaped corner slits can be combined to from a wide CP bandwidth of larger than 40 %. The main features of the dual-band CP printed slot antenna are an embedded slot into the feeding signal line and a pair of inverted L-shaped slits at two corners of L-slot. The lower CP frequency band is created by the original L-shaped slot. The embedded slot is employed to create a first high-frequency CP band, while a pair of inverted L-shaped corner slits to create a second higher-frequency CP band. The two high-frequency CP band can be integrated to a CP band. The CP bandwidths of the lower CP band and higher CP band are both greater than 11%.
