Wireless Communication Diversity Techniques

Beamwidth is the angular separation between the half-power points of the main lobe of an antenna's radiation pattern.

Waveguide Dispersion refers to the spreading of different frequencies, each with its own propagation velocity, in a waveguide.

Frequency Diversity involves transmitting the same signal simultaneously over different frequencies to improve signal reliability.
