SECTOR and MULTI-SECTOR ANTENNAS
Sector antennas are normally used as part of a base station, for example WiMAX/LTE networks. They have narrow elevation and clearly defined azimuth coverage. The image to the right shows the relative size of sectors with different gain at the same frequency.
They have wide azimuth coverage, 30° to 210° in horizontal plane wth profiled vertical coverage.
Sector antennas are used in WiMAX/LTE, WLAN, WiFi, Cellular and other communication systems in the 900MHz, 1800MHz, 1900MHz and 2175MHz systems, microcell ad picocell systems where there is dense RF traffic and in the 2.4GHz, 3.5GHz and 5.5GHz, and up to 10GHz and 15GHz frequency bands.
Sector antennas provide wide area coverage for military and security applications.
Characteristics
- Low profile
- Azimuth coverage from 30° to 210°
- Polarisation can be: Vertical; Horizontal; Dual Vertical & Horizontal; Right Circular; Left Circular; Dual Circular; Dual ±45°
- Gain up to 20dBi dependent on beamwidth
- Multi-sector arrays provide high gain and wide area coverage
Elevation patterns can be designed with null-fill, electrical downtilt and sidelobe suppresion.
