Q:

High directivity required in RADAR communication is satisfied using this type of antennas:

A) Wide band antennas B) Antenna arrays
C) Slot antennas D) Patch antennas
 
Answer & Explanation Answer: B) Antenna arrays

Explanation: Higher directivity is the requirement in point to point communication. This can be achieved by increasing the size of the antennas in terms of electrical length. When much high directivity is required, antenna arrays are used.

Q:

The antennas which offer high operational bandwidth and the antenna parameters are maintained over a wide range of antennas are called:

A) Wide band antennas B) Array antennas
C) Parabolic antennas D) None of the mentioned
 
Answer & Explanation Answer: A) Wide band antennas

Explanation: In this class of antennas, constancy of impedance and radiation characteristics is maintained over a wide range of frequencies. To be wide band or frequency independent, antennas should expand or contract in proportion to the wavelength.

Q:

Lens antennas are classified into two types. One being fast antenna, the other one is:

A) Slow antenna B) Delay antenna
C) Dynamic antenna D) None of the mentioned
 
Answer & Explanation Answer: B) Delay antenna

Explanation: In delay lenses, the electrical path length is increased or the wave is retarded by the lens medium. Dielectric lenses and H-plane metal lenses fall in this category.

Q:

______ antennas have gain less than reflector antennas but have more lenient tolerance on surfaces.

A) Helical antennas B) Lens antennas
C) Array antennas D) Slot antennas
 
Answer & Explanation Answer: B) Lens antennas

Explanation: Lens antennas are complex in nature but are able to scale wider angles. In comparison to reflectors, their gain is 1 or 2 dB less, but these have more lenient tolerance on surfaces. These have less rearward reflection, relatively low loss and can be easily shaped to the desired contours.

Q:

The pattern of the reflector in a reflector antenna is called:

A) Primary pattern B) Secondary pattern
C) Reflector pattern D) None of the mentioned
 
Answer & Explanation Answer: B) Secondary pattern

Explanation: In a reflector antenna, the feed pattern is called primary pattern and the pattern of the reflector is called secondary pattern. These antennas are widely employed in RADARs and other types of point to point communication links.

Q:

Reflector antennas are widely used to modify radiation patterns of radiating elements.

A) True B) False
 
Answer & Explanation Answer: A) True

Explanation: Reflector antennas are used to modify radiation patterns of radiating elements. Reflector antennas are classified into two categories. They are passive reflectors and active reflectors. Based on the type of the radiating element and the modification in the radiation pattern required, accordingly either active or passive reflectors are chosen.
