| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We propose two antennas that improve a null depth of null steering antennas. The antennas are supposed to be used for indoor estimation. The proposed antennas are based on two dipole antennas and a reflector. The first antenna has two parasitic elements on the edge of the reflector, resulting in forming a deep null regardless of the scanning direction. The second antenna replaces the antenna reflector with a metasurface to reduce distortion between individual element patterns in the array and improve null accuracy. Calculation results show that the two proposed antennas formed a null 15 dB deeper than the conventional antenna array. | |
