The ratio of adjacent spacing of dipoles and its lengths in the LPDA are not equal.

(a) True

(b) False

I had been asked this question in an interview for internship.

I'd like to ask this question from Frequency Independent Antenna in section Frequency Independent Antenna of Antennas

Right answer is (b) False

Best explanation: The ratio of adjacent spacing of dipoles and its lengths in the LPDA are equal. The electrical properties of the log periodic antenna are repeated periodically in terms of logarithmic frequency. The relation between the antenna dipole adjacent lengths, spacing and the scaling factor is given as\(\frac{L_N}{L_{N+1}} =\frac{S_N}{S_{N+1}} =τ.\)
