| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Massive Multiple-Input Multiple-Output (Massive MIMO), which uses a large number of antenna elements, has been investigated to realize high-speed and high-capacity wireless communications. However, as the number of antennas increases, the number of digital-to-analog converters, amplifiers, and feeder circuits also increases. In addition, it has the problem that circuit mounting becomes difficult due to the narrow antenna spacing and increased loss and phase deviation of connectors and wiring, especially in the millimeter-wave band. To solve these problems, we propose a compact Massive MIMO configuration. The proposed antenna is composed of a one-dimensional patch array antenna and a Butler matrix, which are stacked on top of each other in a staircase configuration. The proposed antenna is fabricated by stacking several identical substrates, reducing design and manufacturing costs. Simulation results show that the proposed antenna has the same radiation characteristics as the conventional antenna when the substrate thickness is less than 0.1 wavelength. Furthermore, the proposed antenna can reduce the sidelobes and backlobe. | |
