Abstract

A novel loop-loaded printed dipole (LLPD) with a wideband balun structure is presented for aiming a dual-band antenna operation at 3.0/5.5 GHz bands. The proposed balun structure alone demonstrates VSWR<1.5 performance over a 3:1 bandwidth. As the loop elements placed on the antenna aperture provides dual-band operation with at least 15% impedance bandwidths, the wideband balun/feed allows for matched and balanced excitation for the dipole over the bands of interest. An equivalent circuit modeling of the LLPD antenna is presented along with the corresponding simulations and measurements.
