A wide operating bandwidth for a single‐layer equilateral‐triangular microstrip antenna can be obtained by embedding a pair of asymmetric bent slots inside the patch and inserting an inset microstrip‐line section at the patch edge as an integrated reactive load. With the proposed design, a group of three closely excited resonant modes of similar broadside radiation characteristics near the fundamental resonant mode of a corresponding simple equilateral‐triangular microstrip antenna can be achieved. Results show that an operating bandwidth as large as 4.5 times that of a simple triangular microstrip antenna can be achieved. Details of the antenna design and experimental results are presented. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 23: 149–151, 1999.
