| Summary: | 碩士 === 大同工學院 === 電機工程研究所 === 86 === In this thesis, study of experimental measurement for dipole feeding of slot antenna on the shielded coplanar waveguide (SCPW) is presented. The input impedances are measured for SCPW slot antenna by varying the length of dipole feed, the length of the slot antenna, and the distance of the ground shielding. The best impedance matching or lowest return loss at the desired frequency can be achieved by choosing proper combinations of the length of the dipole feed, and the length of the slot antenna. The antenna pattern of the SCPW slot antenna is similar to that of the half wave dipole antenna. The bandwidth and antenna gain increases with the increasing of the length of the slot antenna. The antenna gain is independent with the distance of the ground shielding.
