In this paper, a broadband printed dipole antenna (PDA) with improved radiation characteristics is presented for the next fifth-generation (5G) applications. A broadband integrated balun is used to feed the dipole, which consists of a folded microstrip line and an elliptical slot. Antenna radiation characteristics improvement is obtained thanks to triangle shaped dipole, which stimulates the electromagnetic fields to gather in the end-fire direction and consequently enhances the antenna gain. The proposed design is validated by experimental measurements. The designed antenna bandwidth covers from 26.3 to 40 GHz including the dual 5G bands of 28/38 GHz. The proposed antenna provides almost end-fire patterns, relatively flat gain, and high radiation efficiency through the frequency band.
