New antenna technologies are being developed that allow an antenna to rapidly change its pattern in response to changes in direction of arrival of the received signal.
Antenna is a source or radiator of Electromagnetic waves or a sensor of Electromagnetic waves. It is a transition device or transducer between a guided wave and a free space wave or vice versa.
The purpose of this guide is to give you a straightforward and not overly technical overview of antenna design, to provide guidance on choosing the right antenna and maximizing coverage and capacity, …
As we progress, it will be helpful to keep track of the purpose of an antenna: to match the impedance of a circuit with that of free space, for radiation with the desired frequency, orientation, and polarization.

the 3-antenna method. Transmitted and received powers at the antenna terminal are measured between three arbitrary antennas at known fixed distance. The Friis transmission formula is used to develop …
The design and the analysis of antenna arrays is a subject of its own and is also related to signal processing and communication theory. Research is ongoing in the subjects of smart antennas, …
