What is Antenna Beamwidth ?

Antenna beamwidth is measured in degrees between the half power points (3 dB) of the major lobe of the antenna, Beamwidth can be expressed in terms of azimuth (horizontal or H-plane) and elevation (vertical or E-plane). The predominant type of antenna configuration within urban areas at PCS frequencies will be three sectored. This implies that … Read more

What is Antenna Pattern?

Here I write about antenna pattern, Front-to-rear Ratio and Upper Side Lobe Suppression in antenna. Antenna Pattern The pattern is the electromagnetic field of antenna radiation distributed by coordinate along fixed distance. If the pattern is represented by radiation field strength, it is called field strength pattern. If the pattern is represented by power density, … Read more
