Question:

A dipole antenna in free space has a linear current distribution with zero current at each end, and with peak current I₀ at the enter. If the length d is 0.02λ, what value of I₀ is required to

(a) Provide a radiation-field amplitude of 100 mV/m at a distance of 1 mi, at θ = 90◦;

(b) Radiate a total power of 1 W?

Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
