Preliminary results in the development of a compound reconfigurable antenna

This work presents preliminary results in the development of a compound reconfigurable antenna which is both frequency and pattern reconfigurable. It radiates in one of three selectable patterns (broadside, positive tilt, negative tilt) at one of two selectable frequencies (2.4 GHz or 3.5 GHz). The next steps for this work are fabrication and measurement. Implementing bias lines that minimally interfere with performance is not a trivial task, as they will interfere with the current distribution on the antenna and have some effect on the radiation pattern. Additionally, the separation between the driven and parasitic patches will be redesigned so that the beam tilts between frequency modes are nearly equivalent.
