摘要

A metamaterial-filled quarter circular microstrip antenna (meta-QCMSA) is proposed for 5G communications in the 3.5 GHz band. Compared with traditional CMSAs, the new meta-QCMSA is superior in its small patch in the subwavelength scale realized by collaboratively using metamaterial and field symmetry techniques. This combination method is observed to be more powerful than a single method solely used. One practical meta-QCMSA is designed and experimentally demonstrated near 3.5 GHz. Its patch length is 0.1λ0, much smaller than the traditional CMSA. In addition, the compact meta-QCMSA is observed to have a considerable bandwidth of 3.8% and antenna gain of 3.9 dBi in experiments.
