calculation is a key parameter used in design and calculations of WLAN and satellite link parameters.Į.I.R.P. G(dBd) = G(dBi) – 2.15 = 8 dBi - 2.15 = 5.85 dBdĭBi unit and definition of an isotropic antenna used in E.I.R.P. Let’s consider an 8 dBi antenna and calculate its gain compared to the half-wave dipole. G(dBd) - power gain of half-wave dipole antennaĮxample. Remember, that the half-wave dipole has a theoretical gain of 2.15 dB greater compared to the isotropic antenna (because the dipole field intensity in a given direction is greater by 2.15 dB or 1.64 times than the intensity of the isotropic antenna): Let’s calculate how much stronger a 17 dBi antenna receives (transmits) the signal the compared to the isotropic antenna.ġ7 dBi antenna will receive (transmit) the signal 50.11 times stronger than the isotropic antenna. (G) – how much stronger the antenna transmits or receives signal compared to the isotropic antenna (in a linear scale).Įxample. G(dBi) – power gain of the isotropic antenna expressed in decibels The following equation is used to calculate power gain of the isotropic antenna: The following diagrams shows the isotropic antenna: Theoretically, the isotropic antenna is an infinitesimally small point in space, radiating ideally uniformly (isotropically) in each direction in space, without reflections and losses (its radiation characteristics is spherical). In science, the term is used to define the features of objects showing identical and uniform properties in all directions. What are the origins of the term ‘isotropic’? Isotropy and isotropic from Greek ‘isos’ meaning ‘equal’ or ‘same’ and ‘trópos’ meaning ‘sense’ or ‘turn’. Thus, the value can be calculated or expressed in theoretical terms only. It is a theoretical value, since the isotropic antenna does not exist and cannot be designed or constructed.

Please post a comment if you know other great software or links with information about antenna calculator and design programs. However, a cantenna can be made from various cans or tubes of an appropriate diameter. Exe Batch FileĬantennas are typically used to increase the range of (or discover) wi-fi networks.
