| description | Abstract This work aims at realizing an antenna with a stable radiation pattern for base station applications. A novel high‐efficiency shared‐aperture triple‐band dipole array antenna configuration is proposed in sub‐6 GHz microcell base stations in environments where bi‐directional radiation patterns are preferred. The radiators of the antenna are composed of double‐sided square dipole array structures and two novel long‐side monopoles. To verify the principle, the antenna with an overall size of 0.3λ0 × 0.33λ0 × 0.002λ0 (λ0 is the free‐space wavelength at 900 MHz) is fabricated and measured. The measurements confirm impedance bandwidths of 9.5% (840–924 MHz), 21.9% (3–3.74 GHz), and 12.2% (4.9–5.54 GHz), respectively. The second frequency band covers the 5G sub‐6 GHz NR frequency band n78, mainly used in China and some other countries, and the LTE 42/43 bands (3.4–3.6 GHz, 3.6–3.8 GHz). The first and the third bands are also suitable for GSM 900, 5 GHz WiFi and are potential candidates for future 5G developments. The boresight gain is greater than 1, 6, and 10 dBi in these bands, respectively. The measured results also demonstrate that the proposed configuration has stable radiation patterns across the three frequency bands. |
