Question

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

I have been asked this question in an internship interview.

My doubt is from Time Division Multiplexing in division Multiplexing & Sampling of Bandpass Signal of Analog Communications

Answer 1

The correct choice is (b) in two directions

To explain: As the name suggests, half wave dipole is half wavelength long. This antenna has the shortest resonant length that can be used for a resonant dipole. The field strength of a horizontally polarized half wave dipole antenna is strongest in two directions.
