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 antennaI 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»

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.
