Orientation Diagrams: Elliptical polarized antenna
Elevation Azimuth
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.
