Abstract : A comparison is made on the properties of an equally-spaced, identically-driven N-elements circular array with a circumference less than a free space wavelength, and an electrically thick tubular dipole antenna with a radius equal to that of the array. In the case of an array with infinite long elements, it is found that two current distributions differ from each other only by a term which is in the order of 1/N Log N. In the case of an array with elements of finite length, a modified King's three term theory has been applied and compared with the numerical solution of an electrically thick tubular dipole antenna.
