Hi everyone,
I want to design a reflector antenna working at 10 GHz. How can I find the maximum E.I.R.P for this band?
I also need the regulations for radiation pattern?
If possible give me some reference for that.
Please help me.
For any antenna, EIRP is simply the product of antenna gain in a desired direction and the RF power at its input.
The radiation pattern is s feature of each particular antenna. To my knowledge there are no "regulations" for it.
The regulations valid for a particular frequency are the official rules for the mutual interference levels between or among two or more communication or other type systems sharing a particular frequency and band width.
In UK, contact the Regulatory Commission of the Ministry of Posts and Telecommunications.
Anywhere in civilized countries there are similar authorities that control the frequency spectrum so that the communication, radar and sensors sharing various frequency bands do not cause or suffer by interference.
Certain bands are offered for a "free" use and the authority is not responsible for problems caused by interference. Other bands are "licensed" - the users are charged for their license on using a frequency in that band. For such fee, the authority is responsible for interference problems.
For operating an equipment in a licensed band, authorities issue regulations on EIRP, antenna radiation pattern, etc., so they can be included in their database to indicate potential for causing interference.
