Abstract: The effect of loop shape of the planar loop dipoles to the broad-band input impedance characteristics has been studied by use of an optimization method, the result indicates that the circle is the optimum shape. An example of constructing a parasitic array antenna with broad-band impedance characteristics by use of such an optimum shape dipole is given.

Key words: planar loop dipoles, optimization of input impedance of antenna, broad-band parasitic array antennas
