SECTOR ANTENNAS technical information
Q What is a sector antenna?
A Our sector antennas are normally slim, panel antennas with 20° to 120° beamwidths. Multi-sector antennas consist of several sectors to provide particular coverage requirements.
High gain, up to 20dBi, dependent on beamwidth.
Polarisation can be circular (right hand or left hand), or vertical, or horizontal, or dual vertical and horizontal.

Our printed circuit sector antennas have very low internal losses to make them substantially smaller in height and depth than a traditional dipole antenna.
Gains range from 10 to 20dBi, with, for example 60° to 80° azimuth half power beamwidths available in sectors antennas measuring 12 to 25mm in depth.
Most of our sectors antennas are slim and flat, however some specifications, such as a multi-sector, dictate that the antenna design is cylindrical or semi-cylindrical.
Radiation patterns - elevation patterns can be designed with null-fill, electrical downtilt and sidelobe suppression

Primary application - area coverage, 20° to 180° sectors but with narrow vertical coverage. Multi-sector arrays provide high gain and wide area coverage.
30°, 45°, 60°, 90°, 120°, 180°
Frequency range for sectors is 800MHz to 18GHz.
Our sectors antennas are often used as indoor antennas for picocell or microcell applications in high density areas.
Vertical, horizontal, circular and dual polarisation available
N-type female connectors, SMA, or 7/16 connectors can be fitted.
Radiation pattern:
Energy is squeezed more vertically than horizontally, providing wide coverage in the horizontal plain and narrow in vertical plain.
Hexagonal multi sector Slim sector with 16dBi gain
An example of azimuth and elevation radiation pattern compliance Azimuth and elevation radiation patterns showing compliance with the technically demanding requirements of an ETSI Point-to-Multipoint specification. EN 302-085 v1.1.2 patterns illustrated are for a 5.8GHz, 120 degree sector with 16dBi peak gain andelevation HPBW of 8 degrees.
