Gain compression — in an electronic amplifier circuit is a reduction in differential or slope gain caused by nonlinearity of the transfer function of the amplifying device. This nonlinearity may be caused by heat due to power dissipation, or by overdriving the… … Wikipedia
Directional antenna — Log periodic dipole array A directional antenna or beam antenna is an antenna which radiates greater power in one or more directions allowing for increased performance on transmit and receive and reduced interference from unwanted sources.… … Wikipedia
directional antenna — An antenna or aerial that radiates and receives signals mainly from one direction. For terrestrial radio communications, directionality in an azimuth or a horizontal plane is important. Directional antennae are either monodirectional,… … Aviation dictionary
Gain — For other uses, see Gain (disambiguation). In electronics, gain is a measure of the ability of a circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output. It is usually defined as the mean ratio of… … Wikipedia

Antenna gain — is defined as the ratio of the radiation intensity of an antenna in a given direction, to the intensity of the same antenna as it radiates in all directions (isotropically). Since the radiation intensity of an isotropically radiated power is… … Wikipedia
High-gain antenna — The high gain antenna (HGA) is an antenna with a focused, narrow radiowave beam width. This narrow beam width allows more precise targeting of the radio signal also known as a directional antenna. Most commonly referred to during space missions,… … Wikipedia
