Abstract :
The components of power radiated from a conical log-spiral antenna have been calculated. As the antenna is shortened it is no longer frequency independent and unwanted radiation components increase. Loading can be used to reduce these components but the load absorbs power. The resulting reduction in efficiency has been found.
