Design of an extremely wideband planar dipole antenna for Sub-3 GHz applications

This paper focuses on the design and fabrication of an extremely broadband microstrip dipole antenna with a joined balun without any additional component for sub-3 GHz usages. The antenna features a dipole fed by a transition from microstrip to slotline. A prototype was created and tested for experimental validation. The antenna’s performance was confirmed by the close consistency between the measurement and simulation results. Measurement results show that the antenna achieves a VSWR < 2 impedance bandwidth with a 5:1 ratio, covering 470 to 2490 MHz. Additionally, the maximum realized gain is 3.08 dBi within the operating frequency range. According to these features, the proposed antenna is suitable for use in ultrawideband sub-3 GHz communication systems.
