30 cm

45 cm​

Answer 1

Answer:

if a half wave dipole antenna is operating at 500MHz then its length is equal to 60cm

Answer 2

a). If a half wave dipole antenna is operating at 500MHz then its length is equal to 60 cm.

Given:

ν = 500MHz

To Find:

Length = ?

Solution:

Dipole Antenna:

• This sort of antenna is broadly used for the reception. It is bent and cut for the effective radiation.
• The total length of wire being used as a dipole is equal to half of the wavelength.
• Such antennas are termed as half-wave dipole antenna or Hertz antenna.

Formula used:

λ = $\frac{c}{v} = \frac{3[10^{8}] }{500[10^{6}] } = 0.6m = 60cm.$

Therefore, if a half wave dipole antenna is operating at 500MHz then its length is equal to 60 cm.
