Abstract

A compact and broadband stub-loaded dual-mode dipole antenna is proposed. In this paper, the first- and third-order modes are combined to achieve broadband frequency response. To do so, the third-order mode is compressed close to the first-order mode by loading two pairs of identical stubs at an optimal distance from the dipole-centre. Stubs are symmetrically loaded to both the arms of the dipole. Stub parameters such as length, width, and location play a critical role in decreasing the third-order mode frequency. Therefore, a parametric analysis is also carried out to see the effects of variation in the stub parameters. The proposed antenna is fabricated, and measurements are performed to verify the simulation results. A good agreement between the simulated and measured results is obtained.
