A novel broadband design 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, and its optimal dimensions for bandwidth enhancement have been experimentally studied. With the proposed antenna design, the antenna bandwidth can be as large as about 2.5 times that of an antenna without reactive loading. Details of the proposed design are described, and experimental results are presented and discussed. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 26: 93–96, 2000.
