PROBLEM TO BE SOLVED: To provide a two-element array antenna wherein beam widths for all frequencies are almost equal to each other and a side lobe level and a back lobe level reach levels not to interfere with other areas.KIMURA YASUKO木村 泰子EBINE YOSHIO恵比根 佳雄...
In27, a millimeter-wave eight-element MIMO antenna array was proposed using beam tilting and high-isolation dielectric resonator. A minimum isolation of 25 dB and a peak gain of 7 dBi were achieved at the cost of large size and fabrication complexity. Similarly, Yagi–Uda antennas for a ...
