A new design of a slot‐loaded rectangular microstrip antenna for single‐feed dual‐frequency operation is proposed and experimentally studied. The slots loaded in the patch are a pair of bent slots centered in the patch and oriented along the resonant direction, with the spacing between the two slots being about half the patch's radiating‐edge length. By varying the bent angle and horizontal‐section length of the slots, the frequency ratio between the two operating frequencies is tunable in a range from about 1.28 to 1.79. The two frequencies are also of the same polarization planes and similar broadside radiation patterns. ©2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 24: 234–237, 2000.
