摘要：
A large-band rectangular-shaped microstrip-fed circular slot antenna is studied in this Letter. In this case, many design parameters of this antenna lead to good impedance matching in a wide frequency bond Although the use of a high-relative-permittivity (epsilon(r) = 4.3) substrate usually restricts the operation bandwidth, the measured bandwidth is from 2.277 to 9.272 GHz, which is approximately 124.6 % (VSWR less than or equal to 2.0). The experimented data for the impedance loci and the radiation patterns of the antenna are also described. (C) 2002 Wiley Periodicals, Inc.
