Novel dual‐frequency operation of a single‐feed rectangular microstrip antenna with an embedded reactive loading is presented. The reactive loading is provided by a structure of two cascaded microstrip‐line sections embedded within a rectangular slot cut in the patch. By selecting suitable dimensions of the microstrip‐line sections and the rectangular slot, the proposed antenna can perform dual‐frequency operation, with a low frequency ratio of about 1.04–1.15 between the two operating frequencies. ©1999 John Wiley & Sons, Inc.
