Convert Dbd to Dbi
The key is that dB and dBi are different units of measure antenna gain is confusing for this reason. DBi is a measurement that compares the gain of an antenna. What Is The Difference Between Dbi And Dbd Everything Rf With this logic antenna having gain of 7dBd will have gain of 914 in units of dBi. . DBd decibel relative to dipole The gain of an antenna can be measured relative to a reference dipole antenna and is expressed in dBd. To convert dBi to dBd. I see on the internet and books dBi dBd 215 or alternatively 214. DBi dBd 215. To convert from dBd to dBi simply add 215 to the dBd value to get the dBi value eg. Power gain relative to the array antenna. There isnt a true conversion between dB and dBi. The conversion is as follows. Using HFSS i got the Gain without unit 0665 relative then i have conveted it to dB using this eq. Some companies present the gain of their antennas in dBi not
