1.	The beam-width becomes narrower on(a) Increasing frequency(b) Increasing antenna size(c) Increasing frequency & antenna size(d) None of the mentionedI have been asked this question during an online interview.My question is from Link Budget Analysis and Error Control topic in chapter Communication Link Analysis of Digital Communications
Answer» Right choice is (c) Increasing FREQUENCY & ANTENNA size For explanation: Increasing EITHER the SIGNAL frequency or antenna size results in narrower beam-width.
