Microstrip Antenna Questions and Answers – Applications

This set of Antennas Multiple Choice Questions & Answers (MCQs) focuses on “Applications”.

1. In mobiles, which of the following antenna is widely used?
a) Microstrip antenna
b) Horn antenna
c) Yagi-Uda antenna
d) Lens antenna
View Answer

Answer: a
Explanation: Microstrip antenna is a printed antenna. It is fabricated using photolithography technique. It is small in size and is used in mobile communication widely. Horn, Yagi-Uda and Lens antennas are large in size.

2. One of the advantages of the Microstrip antenna compared to conventional microwave antenna is _________
a) Small size
b) Low gain
c) No surface wave excitation
d) High gain
View Answer

Answer: a
Explanation: Compared to conventional microwave antennas like wire, lens, reflector antennas, the Microstrip antenna is small in size. It has low gain and has surface wave excitation which is a disadvantage.

3. In Microstrip antennas, the feed line and matching networks cannot be fabricated separated separately
a) False
b) True
View Answer

Answer: a
Explanation: Microstrip antenna is a printed antenna. It consists of a radiation patch on one side of dielectric and a ground plane on other side. The patch is connected to the feed line. In this at fabrication only, the feed line and matching networks are fabricated simultaneously.

4. Which of the following is the application of Microstrip antenna in a telemedicine industry?
a) Wireless Body Area Network
b) Detection of moving targets
c) Rectenna application
d) WiMax
View Answer

Answer: a
Explanation: A 2.4 GHz Wearable Microstrip antenna is used for the Wireless Body Area Network. Detection of moving targets comes under radar application. Rectenna is a special rectifying antenna used to converts directly the microwave energy to the DC power. WiMax is an IEEE 802.16 standard used for communication.

5. Rectenna Application of Microstrip antenna converts _______________
a) Microwave energy to DC power
b) Microwave energy to AC power
c) Microwave energy to solar energy
d) Inductive to capacitive
View Answer

Answer: a
Explanation: Rectenna is a special rectifying antenna used to converts directly the microwave energy to the DC power. This is used in the long distance links. It is a combination of antenna, rectification filters and rectifiers.
