Abstract: Low-band radiators of an ultra-wideband dual-band dual-polarization cellular basestation antenna and ultra-wideband dual-band dual-polarization cellular base-station antennas are provided. The dual bands comprise low and high bands. The low-band radiator comprises a dipole comprising two dipole arms adapted for the low band and for connection to an antenna feed. At least one dipole arm of the dipole comprises at least two dipole segments and at least one radiofrequency choke. The choke is disposed between the dipole segments. Each choke provides an open circuit or a high impedance separating adjacent dipole segments to minimize induced high band currents in the low-band radiator and consequent disturbance to the high band pattern. The choke is resonant at or near the frequencies of the high band.

Abstract translation: 提供了超宽带双频双极化蜂窝基站天线的低频带辐射器。 双频带包括低频和高频带。 低频带辐射器包括一个偶极子，具有适用于低频带和连接到天线馈线的两个偶极臂。 偶极子的至少一个偶极臂包括至少两个偶极子段和至少一个射频扼流圈。 扼流圈设置在偶极子段之间。 每个扼流圈提供开路或隔离相邻偶极子段的高阻抗，以使低频带辐射器中的诱发高频带电流最小化并导致对高频带图案的干扰。 扼流圈在高频带的频率处或附近谐振。
