Many original FM antennas were designed as top-mounted radiators, which should produce a fairly uniformly circular radiation pattern. However, sometimes it became necessary to side mount an antenna ...

A non-directional antenna installation, if the pattern was never measured on a test range or confirmed by aerial measurements, will often have a coverage area far different than shown on a coverage ...

Controlled radiation pattern antenna (CRPA) technique is considered to be the best ... conceive, realize, and evaluate a circular array composed of seven elementary patch antennas (see Figure 1).

The single-feed antenna is a square patch, with truncated corners to achieve circular polarization ... an increase in the feeding points leads to more uniformity in the radiation pattern and ...

Radiation patterns for antennas can be utterly confusing, especially when presented in two dimensions, as they usually are. Fear not, [Hunter] has your back with 3D printed and color-coded ...

The spherical geometry used for sampling is the most versatile and allows measurements of both omnidirectional and directional antennas. StarLab uses a circular probe array to provide real-time ...

After building the Yagi, the predicted tuning and impedance matched the real antenna nicely. But what about the radiation pattern? To test that, he used a NanoVNA and a clever test setup.

The radiation pattern is an intuitively appealing method to ... but in every case only half the transmitted power can be received. Figure 34. Circular Polarization interacting with Linear Antenna. A ...
