WiMAX Base-Station Antennas Close Coverage Gaps

A series of wideband WiMAX base-station antennas delivers single and double null fill capability for optimized coverage. The antennas' design also allows for higher system performance by providing isolation specification.

The antennas cover a frequency range of from 2.3 to 2.7 GHz and are available with a variety of gain and beamwidth options to cover deployment scenarios in urban, suburban, and rural environments. Their single and double null fill capability resolves coverage issues for subscribers closer to the base station. Based on the model, the antennas provide upper side-lobe suppression of better than 15 dB or 20 dB, minimizing interference to neighboring cells. A proprietary design provides superior port-to-port isolation of 30 dB. The reduced interference between the two antenna ports leads to better WiMAX network performance; specifically, higher data rates for subscribers.

Antennas are available in both 28-in. and 48-in. radomes for higher gain. All include a standard robust adjustable scissors mount.
