Abstract
A tunable microstrip antenna with circular polarization across a frequency span of 1.4:1 is presented. A dual mode microstrip antenna element with independent frequency control for each polarization is designed. Circular polarization is then achieved with both modes tuned to resonate slightly offset from the intended operating frequency. Measured return loss and patterns are presented.
