Abstract: Adaptive tunable antenna system includes a first radiating element having an elongated length and a second radiating element extending from a distal end of the first radiating element. The first radiating element is for a high band of operation and the second radiating element is for a low-band of operation. The second radiating element is a helical member including a plurality of turns. A low-band circuit selectively bypasses one or more of the turns of the second radiating element in response to a control signal.

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: A dual band inverted-F antenna includes a first antenna element having a first leg connected to a ground plane and a second leg extending along a length from the first leg to a distal end of the second leg. A second antenna element connects to the second leg at a first connection point that is proximal of the distal end of the second leg, the second antenna element electrically coupled to an antenna signal trace of a PCB. A third antenna element is spaced from the second leg of the first antenna element by a gap and positioned along the length of the second leg proximal of the distal end of the second leg but distal of the first connection point. A trap is operatively coupled across the gap between the second leg of the first antenna element and the third antenna element.
