An ultra‐wideband dual‐polarized structure based on a biconical antenna for direction finding application from 2 to 18 GHz is proposed. In addition to direction finding, the proposed structure may be used for broadband communications and radar systems. The structure consists of a biconical antenna that is surrounded by 5 layers of polarizers, which create slant polarization to receive both vertically and horizontally polarized signals. The VSWR is below 2.5 in the operational bandwidth. The whole structure has been simulated using CST software, fabricated, and measured. A good agreement between measurements and simulated results is observed.
