Find out how we use the "substitution method" to accurately measure broadband antenna gain and plot 1D/2D/3D antenna gain radiation patterns.

Is More Antenna Gain Better? The Logarithmic dB Scale Antenna engineers use a logarithmic scale to express this apparent 2x (times two) mirror power doubling as “+3 dBi”. It still means “doubling”. Here are some other examples of ratios or multipliers on the engineering dBi gain log sca...
Specifying antenna gain in dBd means that the antenna in question has the ability to focus the energy x dB more than a dipole. Beam Width Because higher gain antennas achieve the extra power by focusing in on a smaller area it is important to remember that the greater the gain, the smalle...

Accordingly also in the horizontal plane a beam can be created with each halving of the beam width the gain is increased by 3 dB (the shown patterns are theoretically). The resulting gain of an antenna is the sum of the “vertical” and “horizontal” gain ...
A note on Units for Antenna Gain If you look at the specification sheet for an antenna, you will typically see units for antenna gain listed in dB, dBi or dBd. I define these terms below: dB - decibels, as we have been discussing. 10 dB means 10 times the energy relative to an iso...
3-dB beamwidth: The two-sided angle (in one plane) between the angles at which the antenna gain is reduced to half of the gain at the bore- sight (i.e., 3-dB gain reduction). Note that all beamwidths are “two-sided” values. For example, in an antenna with a 3-dB beamwidth ...
Directivity and Gain Directivity and gain are two related antenna parameters that often get confused. First let's talk about directivity. In order to understand directivity, let’s first talk about isotropic antennas. Isotropic antennas have unity directivity. The power of the transmitter is spread...
