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 band. Although the use of a high‐relative‐permittivity (ε 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 ≤ 2.0). The experimented data for the impedance loci and the radiation patterns of the antenna are also described. © 2002 Wiley Periodicals, Inc.
