A circular monopole antenna incorporated with notched slots and modified partial ground plane for 5G applications is demonstrated in this paper. The proposed antenna is fed by a 50 Ω tapered microstrip line, and printed on a FR4 substrate material with relative permittivity of 4.3 and height of 1.6 mm. All suitable parameters have been accomplished to attain the 10 dB return loss bandwidth over 2-6 GHz.This antenna produces a stable omnidirectional pattern with minimum and maximum gains of 2.04 dBi and 4.67 dBi, respectively over the interested band. In addition, the proposed design was fabricated and the prototype was verified to have comparable S-parameters and radiation patterns with that of the simulated results. Evidently, simulated results are reasonably in excellent agreement with the experimental results.
