摘要： A circulator includes a ferrite disposed above a PCB, a metal cover that covers above the ferrite and is formed integrally, a plurality of connection parts that electrically connect the metal cover to a plurality of respective signal transmission lines above the PCB, and a permanent magnet that applies a magnetic field to the ferrite. Thus, it is possible to provide, for example, a non-reciprocal circuit element that is composed of a small number of parts and can be easily mounted on a circuit board, a communication apparatus equipped with a circuit including the non-reciprocal circuit element, and a manufacturing method of a non-reciprocal circuit element.

摘要： Impedance optimization is difficult in microwave-band waveguide converters. To solve that problem, this waveguide converter is provided with the following: a waveguide provided so as to introduce microwaves to an antenna that performs input and output in a planar microwave circuit; a terminal waveguide that faces the aforementioned waveguide with the antenna interposed therebetween and connects to said waveguide so as to terminate same; and a conductor plate mounted so as to face the antenna. The conductor plate is electrically connected to at least part of the inside wall of the terminal waveguide.

摘要： A communication device 1 (transceivers 400) transmits a training signal from its own transmitting antenna while performing beam scanning, and a communication device 2 (transceivers 500) receives this training signal in a state where a quasi-omni pattern is generated in its own receiving antenna. Further, the device 1 transmits a training signal in a state where a quasi-omni pattern is generated in the transmitting antenna, and the device 2 receives this training signal by the receiving antenna while performing beam scanning. The device 1 and 2 detects, from respective reception results, transmitting-antenna-setting candidates of the device 1 and receiving-antenna-setting candidates of the device 2, and determines antenna-setting pairs (combinations of antenna-setting candidates). The above-described processes are also performed for a receiving antenna of the device 1 and a transmitting antenna of the device 2. The device 1 and 2 communicates by using the obtained antenna-setting pairs. In this way, when radio communication is performed by using beam forming, the time necessary for finding and setting a beam direction is reduced, thereby reducing the transmission-disconnected time.

摘要： Antenna 2 and radio communication apparatus 1 include mount portions 9 and 15, flat proximity opposing surfaces 13 and 20, and waveguide portions 12 and 19 penetrating through proximity opposing surfaces 13 and 20, respectively. For example, in proximity opposing surface 13 of radio communication apparatus 1, choke groove 14 is formed outside waveguide portion 12. With mount portions 9 and 15 of antenna 2 and radio communication apparatus 1 abutted against and fixed to each other, proximity opposing surfaces 13 and 20 are set parallel to, and directly opposite to each other with a clearance interposed therebetween so that waveguide portions 12 and 19, opposite to each other and with a clearance, form a waveguide.
