Abstract
Cross dipole antenna for base station applications is presented in this paper. The proposed antenna consists of simple dipole elements and modified balun structure for the improved performance. The proposed design is simple and suitable for 4G and sub-6 GHz 5G base station applications. The antenna is fabricated using low-cost FR4 epoxy substrate with a dielectric permittivity of 4.4. The height of the substrate is 1.6 mm and loss tangent is 0.02. In order to confirm the proposed design, the antenna is measured and compared with the simulation results. The proposed antenna is achieved 13.8 dBi of realized peak gain in the 1.341 to 3.834 GHz frequency range along the bandwidth of 2.492 GHz with VSWR < 1.5. The proposed antenna obtains stable radiation patterns and stable gain over the frequency range. The cross dipole antenna structure with the proper radiation performance makes the proposed antenna suitable for base station applications.
