What does BW stand for?

3dB beamwidth in [theta] and [phi] planes for A = 1.

In addition, the ultra narrow beamwidth of these links provide an added level of security and interference immunity that other wireless solutions do not offer.

When the beamwidth of a directional antenna is lessened (a narrower beamwidth), the interference caused by the antenna will also be reduced.

It used Sar techniques and exploited the fact that since the radial velocity of the ground relative to the aircraft varies with the angle from the aircraft track, the antenna beamwidth could be considered as a series of angular sub-divisions, each having radar returns with a slightly different radial velocity, a characteristic that could be used to discriminate between them.

The antenna has a very broad response -- about 12 GHz -- and a beamwidth of about 90 degrees.

Typically, the hub antenna has a beamwidth of 90[degrees], while the CPE antenna has a beamwidth of 2[degrees] to 3[degrees].

8-degree horizontal and 25-degree vertical beamwidth.

In its simplest configuration, circular or elliptical antenna can be designed to produce a broad beamwidth as well as broadband with linear polarization and a radiation pattern having a broadside maximum.
