Basic Antenna Terms and Definitions
special cases of elliptical polarization are linear polarization and circular polarization. The initial polarization of a radio wave is determined by the antenna that launches the waves into space. The environment through which the radio wave passes on its way from the transmit antenna to the receive

. Polarization. If we use a linearly polarized antenna to measure the pattern radiated by a circularly polarized antenna, the. relative pattern will not change but the absolute values of signals measured will be down by 3dB since we are only. measuring one of the "two orthogonal linearly polarized

Panel Antennas
a microstrip-patch or planar array antenna, or multiple dipoles. The cell site can use several panel antennas or bays of panels (as required) to provide coverage. Microstrip or patch antennas are readily manufactured using printed circuit methods and feature good, linear-polarized radiation patterns

PICO01: The Choice of Polarization - Indoor Picocell Antennas
polarized signal is comprised of two orthogonal (right-angle) linear signals separated 90 degrees in electrical phase. (The vertical and horizontally polarized signals are spatially 90 degrees apart, with a 90 degree time delay built into the antenna design.) Because different linear polarizations

Phased Arrays
of a particular field component at the output relative to the phase at the input. Several types of driven phased arrays are possible such as collinear, franklin, curtain, linear or 1D, planar, circular, 2D & 3D. Planar array antenna has all of the active and parasitic elements in one plane

What is Polarity? (.pdf)
. Dual Polarized. Electromagnetic waves can propagate with linear, circular or el iptical polarization. Linear polarization is the most popular method used in WiFi. communications and can take two forms, vertical and horizontal. Some antennas utilize dual polarity which provides access
