Abstract: | Based on the multi-split resonant ring structure, a dual band broadband left-handed material is proposed. The structure is composed of a rectangular resonant ring and inverted H-shaped load line, and it has a wide frequency band, adjustable frequency and is easy processed. The parameters are extracted by software simulation and physical test, and the results show that the left-handed bands of the structure are located at 7.8-8.2 GHz and 8.4-13.4 GHz respectively, and the total bandwidth is 5.4 GHz. Compared with the traditional structure, this structure has wider bandwidth and can adjust the left-hand band in a certain range. |
