A tunable flltering antenna (flltenna) realized using rings fed with an ultra-wideband (UWB) planar, elliptical monopole antenna is proposed. An array of slotted rings with varactors is placed in close proximity of the planar monopole to obtain the low proflle tunable flltenna. The array of rings can be viewed as a small tunable frequency selective surface. The design produces a tuning range of about 3.8{ 4.4GHz over a varactor reverse bias voltage of 1{4V.
