The aim of this report is to research wireless antennas and differences between them. Antennas are included 3 types: omnidirectional‚ semi-directional‚ and highly-directional. Any antenna has three fundamental properties: gain‚ directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link‚ warehouse‚ hotspot‚ trade show‚ airport. The omnidirectional antennas transmit a signal in all directions‚ it is known dipole ("non-directional") antenna. The
