Question 1

What is the other name for half-wave dipole antenna?
A)helical antenna
B)isotropic antenna
C)hertz antenna
D)maxwell antenna

Accepted Answer

The half-wave dipole antenna is also known as a Hertz antenna, named after Heinrich Hertz who demonstrated the existence of electromagnetic waves.

Question 2

Measured on the ground, the field strength of a horizontally polarized half wave dipole antenna is strongest_________      
A)in one direction
B)in two directions
C)depends on the number of elements
D)depends on the shape of antenna

Accepted Answer

The field strength of a horizontally polarized half-wave dipole antenna is strongest in two directions, perpendicular to the axis of the antenna, forming a figure-eight pattern in the horizontal plane.

Question 3

When an antenna radiates more energy in one direction than in other directions, it is called_________      
A)selectivity
B)directivity
C)active antenna
D)resonance

Accepted Answer

Directivity refers to the measure of how focused the radiation pattern of an antenna is in a specific direction. An antenna with high directivity concentrates energy more efficiently in one direction, enhancing its performance in that direction compared to others.

Question 4

What is the full form of ERP?
A)effective radiated power
B)effective reflected power
C)equivalent radiated power
D)equivalent reflected power

Accepted Answer

ERP stands for Effective Radiated Power, which is a standard measure of the power radiated by a transmitter in a specific direction, typically used in broadcasting and telecommunications.
