摘要：
We investigate two novel microstrip-line antennas. They are composed of symmetric and asymmetric dual-loop radiation elements, respectively. Based on the radiation characteristics of the symmetric (reference) antenna, the asymmetric (present) antenna is designed using the method of moments. It is found that the present antenna radiates a circularly polarized wave with an axial ratio of less than 3 dB in a frequency bandwidth of 10%, which is wider than that of the reference antenna by a factor of three. The theoretical results are validated by experimental ones.
