A V-band wide-beamwidth left-handed circularly polarized wire-bond antenna is presented in this paper. The proposed design, which is implemented by using integrated passive device process, consists of a 1:4 series-type ring-shaped microstrip power divider and four bond-wire radiators. The design of bond-wire radiator with wide-beamwidth characteristic is described. The design method of power divider is also explained in detail. The proposed antenna has been fabricated and measured. The area of the fabricated antenna is of 2.2 × 2.2 mm2. The simulation and measurement regarding antenna reflection coefficient, radiation pattern, peak gain, and axial ratio are conducted for design validation. The measured results show that the antenna can operate in V-band and the impedance bandwidth with |S11| less than-10 dB is from 51 to 67 GHz or more (<28%). The measured peak gain is-0.8 dBi at 58 GHz. The measured axial ratio is less than 3 dB 55 to 65 GHz. The simulated 3-dB antenna beamwidth is more than 180°.
