1.	Antenna separation effectively controls _________(a) directivity(b) external noise(c) self-generated interference(d) external interferenceI have been asked this question in an interview for job.I'd like to ask this question from Antenna Tradeoffs topic in section Technology Tradeoffs in Software Defined Radio of Cognitive Radio
Answer» Correct choice is (c) self-generated interference The explanation is: ANTENNAS in same enclosure or when CLOSELY spaced OFTEN lead to interference. This can be mitigated by ANTENNA separation. The benefit of separation can be ESTIMATED by link-based spreadsheet.
