STUDIES OF BANDWIDTH ENHANCEMENT OF PRINTED SLOT ANTENNAS

by Chiou, Jhy-Ying

Novel printed slot antennas are demonstrated in this thesis. For the linear polarization design, CPW-fed strip-loaded square slot antenna is presented for achieving broadband operations. For the circular polarization, two novel antenna designs are also presented¡Fone is a CPW-fed square slot antenna with an inverted L tunning stub, and the other is a microstrip line-fed square slot antenna with a conducting strip from ground plane for broadband circularly polarized radiation. Finally, an antenna design having compact size and broadband characteristic is shown.
