How an antenna radiates
Webantennas are shown in Section 10.2 to have stable directional properties far from the antenna (the antenna far field), and different directional properties closer than ~/2λπ (the antenna near field). In Section 10.3 these properties are related to basic metrics that characterize each antenna, such as gain, effective area, and impedance.

WebI've been looking around for antenna ideas and ive seen the ring loop maybe magnetic antennas and was wondering why a deasign like that isnt used for gmrs. i have some knowlege as to how the antenna radiates out but obviously not knowlegable enough to understand why the loops are not used aside from the inline loops on pole thing.

The reactive region extends from the surface of the antenna to (for electromagnetically short antennas that are less than λ/2 in length, we use R = λ/2π = 0.159λ). The radiative region extends from to a generally accepted transition to the ‘far-field’ at 2D 2 /λ.
