The dual‐band conical‐pattern radiation of a stacked circular microstrip antenna is demonstrated. The antenna studied consists of two stacked circular microstrip patches and an air layer in between, and is fed by a probe feed at the lower circular patch. By varying the air‐layer thickness, the frequency ratio between the two operating frequencies is varied. Experimental results from the constructed prototypes show that a frequency ratio ranging from about 1.26 to 1.37 can be achieved. Also, both of the two operating frequencies have good conical radiation patterns. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 202–204, 2001.
