摘要： The proposed antenna structure has first and second asymmetric radiated-strip structures developed by modifying the structure of a printed T-type monopole. Specifically, by combining the radiated-strip and the shorting-line, the proposed antenna structure is similar to modified Type III balun and dipole fed by microstrip-line structure. Hence, the proposed antenna structure can also be regarded as a “quasi-balanced” antenna structure.
