| Abstract(in English) | Recently, the data transmission rate is increasing in the communication systems. The new system like ultra-high-speed WLAN (Wireless Local Area Network) has attracted much attention using millimeter wave (mm-wave). However, the higher transmit power is necessary to overcome the higher path loss at mm-wave. Therefore, a high-gain antenna is required to overcome this problem. The beam scanning antenna can be one of the solutions for achieving high gain to any direction. In this report, we proposed a dielectric cylinder-loaded sector antenna and analyzed the radiation pattern characteristics for the shape of the dielectric cylinder. In the sector antenna, the radiation pattern characteristics are improved by optimizing termination conditions at parasitic elements. With a single dipole, the maximum actual gain at 60 GHz becomes 7.27 dB at h/λ_0=0.182 and γ/λ_0=0.403. Also, the sufficiently narrow beam can be formed, i.e., the -3 dB beam width is 49 °. With 6 sector, the maximum actual gain of 14.14 dB at 60 GHz is achieved by optimizing termination conditions at parasitic elements. It was clarified that the proposed antenna is effective in achieving high-gain and miniaturizing the size of the antenna. |
