| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We have developed the liquid crystal loaded phase shifter as the adaptive device operating in microwave frequency, and are examining adaptive array antenna using that phase shifter. First, we have studied linear array antenna with four elements, and realized antenna which gain is 12.8 dB at 20 GHz. But, return loss of the antenna at 20 GHz is －13 dB and have some resonance frequencies due to structure of linear array antenna. We adjust impedance of the antenna by installing short stub on coplanar waveguide for solving those problems. As a result, we realize to eliminate redundant resonance frequencies and to improve return loss S11 at 20 GHz. | |
