Radiation Pattern of Antenna

Radiation Pattern of Antenna shows the distribution of energy radiated by the antenna in space. More simply, the radiation pattern is a trace out that corresponds to the radiation properties of the antenna in space coordinates (i.e., with respect to angle and distance). It is a graphical way of showcasing the radiation from the antenna …

Adcock Antennas

Adcock Antennas are basically arrangements of multiple vertical antennas in space-separated at some specific distance. It was proposed by an Engineer from British origin named Lient Adcock in 1916. Thus, so this antenna was named after him. Adcock antennas are used for the purpose of transmission or reception of directional radio waves. However, at the …

Anechoic Chambers

Definition: “An-echoic” is a word that means “non-reflective“. Sometimes it signifies non-echoing or free of echoes. Anechoic Chambers are basically enclosed indoor rooms whose walls, ceiling and floor are covered with a layer of absorbent that absorbs radio-frequency energy that helps to reduce reflections. As it is an indoor chamber thus, for the small antennas …

Antenna Polarization

Definition: Antenna Polarization is the term used in correspondence with the electromagnetic wave radiated through it. It is defined as the orientation of the electric field vector of the radiated electromagnetic wave by the antenna with a negligible amount of losses. Polarization of the antenna is regarded as a crucial parameter and must be considered …

Antenna Apertures

Definition: Antenna apertures are used in reference to the area of the antenna. It is defined as the measure of the ability of the antenna to effectively receive the power radiated towards it. As the term is associated with the area of the antenna, thus, shows the power capturing characteristics of receiving antennas. The aperture …
