Abstract

Two compact and wideband dipole antennas are proposed in this paper. The first dipole operates at a low-frequency band from 77.8 MHz to more than 500 MHz with VSWR lower than 2.5:1 and lowest realized gain of-25 dBi at 80 MHz. The second antenna operates at a higher frequency band from 0.5 GHz to more than 6 GHz with VSWR lower than 2.8:1 and a minimum realized gain of-6 dBi at 0.5 GHz. The low-frequency dipole has a diameter of 0.04 λ_fmin and a height of 0.13 λ_fmin, where λ_fmin is the free-space wavelength at the lowest frequency of operation. While the high-frequency dipole has a diameter of 0.15 λ_fmin and a height of 0.13 λ_fmin, where λ_fmin is the free-space wavelength at the lowest frequency of operation. Both dipoles rely on the monopolar-patch antenna with wideband feed strategy. A curved cone is utilized as the wideband feed. The low-frequency dipole is fed by a surface-mount RF transformer, which serves as a balun from the coaxial cable to the dipole antenna. The high-frequency dipole is fed by a printed broadband microstrip line to double-sided parallel-strip line transition. These two dipoles are fabricated and measured. The measured VSWR results consistent with the simulated ones for both dipoles.
