A frequency reconfigurable rotatable microstrip antenna design

This paper presents a new frequency reconfigurable antenna design. The reconfigurability is achieved via a rotational motion of a part of the antenna patch. The rotating part has the form of a circle and contains four different shapes. Each shape corresponds to a different antenna structure. With every rotation, a different antenna structure is fed in order to produce a different set of resonant frequencies. A prototype antenna was fabricated and tested to prove the suggested method. A complete agreement was found between the simulated and the measured data.
