This section provides technical information on antenna parameters, electromagnetic simulation, and RF measurements. The articles explain selected aspects of antenna design and performance, with emphasis on the interpretation of parameters used in antenna specifications.
Port-to-port isolation describes the degree of signal coupling between antenna ports. It is commonly evaluated using scattering parameters and is particularly relevant to dual-polarized and multiport antennas.
Radiation patterns describe the angular distribution of antenna gain. They provide information about main beam direction, beamwidth, sidelobes, and radiation outside the intended coverage area.
Impedance mismatch between an antenna and its transmission line causes part of the incident power to be reflected. Mismatch loss can be evaluated using the reflection coefficient, return loss, or VSWR.
Sidelobe level describes the relative magnitude of radiation outside the main beam. Suppressing sidelobes can reduce unwanted signal reception and interference in directional antenna systems.
