Abstract
The phase centre of a dual‐mode circular microstrip antenna is investigated when the fundamental TM~11~ and higher order TM~02~ modes are excited. It is shown that the location of the phase centre can be controlled by the excitation amplitude and phase of these modes. The problem is treated analytically using the cavity model. © 2008 Wiley Periodicals, Inc.
