Super‐wideband two‐arm antenna for future generations of mobile communications

In this paper, a modified rhombic-shaped wide-flare two-arm antenna is proposed for super-wideband applications of the next generations mobile technologies. To enhance input impedance and to improve its performance, copper arms are lithographed on dielectric substrate with multilayers fed through wideband balun that designed feed balanced conventional (unbalanced) coaxial line. The fabricated experimental validation simulation results. It shown electromagnetic as well measurements operational in range frequencies ( 2.3 - 23 GHz $2.3 \mbox{-} 23\unicode{x0200A}\mathrm{GHz}$ ). Parametric study performed obtain optimum design antenna. distributions surface current at different presented discussed more understanding operation over entire frequency band. has radiation efficiency greater than 96%, percentage bandwidth 164%, ratio 10, bandwidth-to-dimension 1360, maximum gain exceeds 5 dBi $5\unicode{x0200A}\text{dBi}$ .
