A function reconfigurable double-helix antenna inspired by DNA is designed. With different lumped elements between the two helixes, the antennas show great function reconfigurability with function 1 as a broadband and high gain antenna, and function 2 as a frequency tunable antenna with a wide tuning range. Each function is discussed in detail. The antenna is circularly polarized. Simulated and measured results of the antenna are observed and analyzed, which show good performance of the two functions.
