Abstract
This study presents a triangle director dipole antenna with a rectangular impedance balun (RIB). The proposed antenna consists of a triangular director, a coplanar waveguide (CPW) to coplanar stripline (CPS) transition line, and the RIB. The proposed triangle director substitutes a typical director of a planar quasi-Yagi dipole antenna. The triangle director has modified a director of a planar quasi-Yagi dipole antenna. The triangle director generates a circular polarization. Also, the RIB has proposed to match an impedance between the CPW-fed to the CPS transition line. It obtains an ultra-wide frequency band of 4020 MHz (2160 - 6180 MHz), and a peak realized gain of 12.5 – 6.2 dBi in the operating frequency band. The proposed antenna shifts the resonant frequency to a lower frequency band of 75% than the typical planar dipole antennas. The proposed antenna uses widely for wireless medical communication, both ISM bands and C-V2X applications.
