This set of Antennas Multiple Choice Questions & Answers (MCQs) focuses on “Smart Antennas – Drawbacks”.
1. Which of the following is the drawback of smart antenna?
a) Design of trans-receiver
b) Spacing between base stations
c) Probability of collisions being reduced
d) Focused to an intended direction
View Answer
Answer: a
Explanation: Design of trans-receiver is a complex when compared to the traditional base station trans-receivers because separate trans-receiver chains are needed for each array elements. Probability of collision reduction, focusing on desired direction is the benefits of smart antenna.

2. Which of the following statement regarding smart antenna is false?
a) Design of transceiver is complex
b) Smart antennas is more directive
c) Smart antenna is more expensive
d) Numeric processors and control systems are not needed in smart antennas
View Answer
Answer: d
Explanation: Compared to the traditional base station trans-receivers, design of trans-receiver is a complex because there is a need of separate trans-receiver chains for each array elements. Smart antennas are more directive and costly. The base stations need very powerful numeric processors and control systems.
