Why is bending the antenna important instead of using parallel wires?

why does the bending of antenna is important?why we can't just use two parallel wire to radiate energy?
thanks.

The fields decay too quickly with distance if the wires are parallel.

In parallel wires, the curernt would flow in opposite directions, cancelling their radiation effect.

The V antenna has nearly-parallel wires, but they are not parallel, and the small angle makes the radiation.
