Explanation:

1. It is a resonant antenna

2. It is exact half wavelength (λ /2) long & open circuited at one end.

3. The dipole antennas have lengths λ /2 , λ , 3 λ /2 etc. which are all multiple of λ /2.

Hence they are resonant.

4. In half wave dipole antennas the forward waves & reflected waves exist. Hence radiation pattern is bidirectional.
