The displacement of the upper patch in the resonant direction in a dual‐band stacked microstrip patch antenna controls the centre frequencies of the bands, their separation, the input impedance, and the radiation pattern at the upper band. The radiation pattern has low sensitivity to the displacement and, hence, dual‐band stacked microstrip patch antennas can be designed with have similar radiation patterns at both bands. © 2004 Wiley Periodicals, Inc.
