22 de jul. de 2024 · Learn the definition, formula and examples of antenna gain, the ability of an antenna to focus RF energy in a specific direction. Find out how to calculate the antenna gain, aperture area and efficiency using decibels and wavelength.
Hace 14 horas · Antenna gain is frequently measured as decibels relative to a half-wave dipole. One reason is that practical antenna measurements need a reference strength to compare the field strength of an antenna under test at a particular distance to.
Hace 2 días · But in a nutshell, you want gain from your antenna where you can use it most. Most times it means putting your antenna up as high as possible. As a long standing rule of thumb: If you double the height of your antenna you will gain 6 db gain!
Hace 4 días · Calculadora de ganancia de antena. La ganancia de la antena es un parámetro crítico en el diseño y análisis de sistemas de comunicación de radiofrecuencia (RF). Cuantifica la capacidad de una antena para dirigir o concentrar energía de radiofrecuencia en una dirección específica.
Hace 2 días · 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, bandwidth, radiation pattern, beamwidth, polarization, and impedance.
18 de jul. de 2024 · Antenna gain is a measure of how well an antenna can focus energy in a particular direction compared to a reference antenna, typically an isotropic radiator (a theoretical “baseline” antenna...
3 de ago. de 2024 · Being log-periodic, the antenna's main characteristics (radiation pattern, gain, driving point impedance) are almost constant over its entire frequency range, with the match to a 300 Ω feed line achieving a standing wave ratio of better than 2:1 over that range.
