This set of Antennas Multiple Choice Questions & Answers (MCQs) focuses on “Patch Types”.
1. Which of the following is the most common version of the printed antenna?
a) Horn antenna
b) Microstrip antenna
c) Wire antenna
d) Lens antenna
View Answer
Explanation: Microstrip antenna is a printed antenna. It is fabricated using photolithography technique. It consists of a radiation patch on one side of dielectric and a ground plane on other side. The patch can be of any shape like circular or rectangular.
2. In which of the following type of antenna a patch is created during fabrication?
a) Microstrip antenna
b) Horn antenna
c) Wire antenna
d) Lens antenna
View Answer
Explanation: In Microstrip antenna patch is created on the dielectric substrate using photo-etching. The shape and size of patch may vary the return loss. Horn, Wire and Lens doesn’t have any patch. Horn is a waveguide antenna and a wire antenna is made of dipoles.
3. In Microstrip antenna, the patch and feed line is photo etched on dielectric substrate
a) True
b) False
View Answer
Explanation: Microstrip antenna is a printed antenna which is fabricated using photolithography technique. Its design process consists of a ground plane and a dielectric substrate in which patch is created. The source is connected to it through a feed line by photo etching process.
4. The shape of the patch in rectangular Microstrip antenna is ____
a) Rectangular
b) Circular
c) Cylindrical
d) Elliptical
View Answer
Explanation: The antenna is named under the shape of the patch. For a rectangular Microstrip antenna, the patch shape is rectangle. For a general Microstrip antenna patch can be any shape like rectangle, circular, elliptic, triangle.
