What is a tri sector antenna?
What is a tri sector antenna?
The TELNET trisector antennas are part of the ENVIA family, a new generation of BTS antennas, with radiating components based on fractal geometry. In addition, the small height and weight of this family of antennas simplifies installation and maintenance tasks.
What is the function of sector antenna?
Sector antennas are used extensively for cellular communication. The largest use of these antennas is for cell phone base-station sites. The coverage area of sector antennas is determined by the projection of the radiation pattern on the ground, which can be adjusted by changing the down-tilt angle of the antenna.
What type of antenna is a sector antenna?
directional microwave antenna
A sector antenna is a type of directional microwave antenna with a sector-shaped radiation pattern. The word “sector” is used in the geometric sense; some portion of the circumference of a circle measured in degrees of arc.
What are three types of antenna types?
3.3. Types of Antennas. There are three main antenna categories available for wireless LANs: Omnidirectional, Semidirectional and Highly directional. Omnidirectional – Omnidirectional antennas are designed to radiate a signal in all directions.
What is antenna and how it works?
How does an antenna work? The antenna at the transmitter generates the radio wave. A voltage at the desired frequency is applied to the antenna. At the receiver, the electromagnetic wave passing over the antenna induces a small voltage. Thus, the antenna becomes the signal source for the receiver input.
What is WiFi sector antenna?
WiFi Sector Antennas provide superior gain and beam performance for high-capacity, multipoint networks. WiFi Sector Antennas have high gain, typically 13 to 16 dBi, and an RF pattern from 60 to 180 degrees.
What is efficiency of an antenna?
Antenna Efficiency is the ratio of power radiated (Prad) by the antenna to the power supplied (Ps) to the antenna. The efficiency of an antenna is usually measured in an anechoic chamber where an antenna is fed with some power and the strength of the radiated electromagnetic field in the surrounding space is measured.
Does antenna shape matter?
Obviously, the waves arriving at an antenna from a transmitter are exactly the same, no matter what shape and size the antenna happens to be. A different pattern of dipoles will help to concentrate the signal so it’s easier to detect.

Why antenna is a transducer?
Antennas convert electrical parameters (current and voltages) into electromagnetic parameters (electric and magnetic fields) and vice versa. Hence, an antenna can be regarded as a transducer or a sensor as it converts electrical energy to electromagnetic energy, or the opposite [1] .
Is higher gain antenna better?
When looking at mobile two-way radio coverage, many users jump to the conclusion that the higher the gain rating is on an antenna, the better the coverage. Since an antenna does not make power, increasing gain in one direction will decrease propagation in another.
