• 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

• Low-gain antenna — The low gain antenna (LGA) is an antenna with a broad radiowave beam width. This very wide beam allows for a more reliable signal that is best used in mountainous regions, where the signal will propagate reasonably well regardless of terrain. The …   Wikipedia

• Antenna measurement — techniques refers to the testing of antennas to ensure that the antenna meets specifications or simply to characterize it. Typical parameters of antennas are gain, radiation pattern, beamwidth, polarization, and impedance.The antenna pattern is… …   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

• Antenna diversity — Antenna diversity, also known as space diversity, is one in a superset of wireless diversity schemes that utilizes two or more antennas to improve the quality and reliability of a wireless link. Often, especially in urban and indoor environments …   Wikipedia

• 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

• Antenna effective area — In telecommunication, antenna effective area or effective aperture is the functionally equivalent area from which an antenna directed toward the source of the received signal gathers or absorbs the energy of an incident electromagnetic wave. Note …   Wikipedia

• Antenna aperture — As a receiver, antenna aperture can be visualised as the area of a circle constructed broadside to incoming radiation where all radiation passing within the circle is delivered by the antenna to a matched load. (Note that transmitting and… …   Wikipedia

• Antenna factor — In telecommunications, the antenna factor AF (unit: 1/m) is defined as the ratio of the incident electromagnetic field strength E (units: V/m or µV/m) to the voltage V (units: V or µV) on the line connection of an antenna:: AF = frac EVIf all… …   Wikipedia

• Antenna effect — The antenna effect, more formally plasma induced gate oxide damage, is an effect that can potentially cause yield and reliability problems during the manufacture of MOS integrated circuits [ T. Watanabe, Y. Yoshida, “Dielectric Breakdown of Gate… …   Wikipedia
