Abstract

Recently, we have analyzed a spirally-wound antenna [1][2] proposed by Fenwick using the method of moments. The analysis shows that the. input impedance is very low (less than 4 ohms). It is also shown that the frequency bandwidth is very narrow (less than 0.2% for a criterion of VSWR = 2 to an input resistance at resonance). In this paper, we realize higher input resistance over a wider frequency band than the Fenwick's antenna. For this, a relatively small spiral-loaded antenna, proposed in Fig. 1, is analyzed. The radiation characteristics are presented and discussed.
