Often, the E-field is either vertical or horizontal as developed by a dipole structure or a ground plane antenna, but it can also be rotary which means it can be rotating around the signal’s axis of ...

Characterising a well-behaved antenna’s radiation properties with two plane patterns in a coordinate system involves azimuth plane pattern and elevation plane pattern. Assuming that the antenna is ...

A novel design inspired by a child's toy, the portable gigahertz QFH antenna can be easily reconfigured for radiation patterns ... the antenna’s ground plane (Fig. 5). The network supplies ...

These techniques involve the three main components of a GNSS antenna: the radiating element, additional ground plane, and the radio frequency ... a more favorable radiation pattern; high low-elevation ...

The ground plane antenna is omnidirectional. The horizontal radiation pattern is a circle where the antenna radiates equally well in all directions. Figure 6 shows the vertical radiation pattern.

The process begain with measuring an element alone on a ground plane, in order to extract the gain, the axial ratio, the aperture angle, the matching values, and every feature that defines a ...

The only truly non-directional antenna is the isotropic radiator, a theoretical construct, which would look like a point source in space with no preferred direction of radiation ... Maxwell’s ...

The radiation pattern of a GPS antenna is first measured on 1 m ground-plane. Then the radiation pattern of the same antenna is measured at three distinct locations on a sedan vehicle. Results are ...
