Abstract

This paper proposes a miniaturized ±45° dual-polarized base station antenna for low-frequency 5G. The original two resonant modes are gradually separated by chamfering the inflected right-angled edges of the radiating arms of the square ring dipole, so as to realize miniaturization and wide bandwidth. To induce a novel resonant mode at elevated frequencies, a compact square ring dipole is strategically positioned within the larger square ring dipole. By fusing multiple resonant modes together, a wider bandwidth is obtained. The outcome reveals that the antenna has S₁₁ and S₂₂ less than -15 dB in 616-992 MHz, port isolation (S₂₁) higher than 33 dB, and gain not less than 8.03 dBi, and the variation of half-power bandwidth (HPBW) within 69±4°, with the size of only 0.38λ₀*0.38λ₀(λ₀ represents the wavelength associated with the center frequency f₀ in a vacuum or free space conditions).
