Linear Polarized Antennas
Because of the smaller apex angle (60º), this antenna is more suited to
selective data collection and restriction of read zones.
Depending on the direction of mounting, the antenna’s field is either
vertically or horizontally polarized, requiring the tag to have the same
orientation.
Because of the greater gain, longer read ranges can be achieved with this
antenna compared to the elliptical polarized type above..
