Hpbw in antenna
Webthat an antenna has a 1° pencil beam and small minor lobes, its gain is approximately 41 000 or 46 dB, give or take a decibel or two, but not that the result is accurate to 1/10 of a decibel or better." The red curve is a more accurate formula which is also consistent with the HPBW-diameter relation WebHPBW = BWFN/ Example 2. A linear uniform array of point sources satisfy the parameters, n = 4, δ = 0, d = λ/2. Obtain the field. pattern and also find BWFN and HPBW. Sol: Given no. of antennas, n = 4, for broadside array, δ = 0,d = λ/ The total filed expressed as. 0. sin 2.
