摘要： A high-frequency module including a transmission line for a high-frequency signal and a waveguide conversion structure, capable of reducing the size thereof, and a method for manufacturing such a high-frequency module are provided. A high-frequency module includes a core material in which a first dielectric layer is provided between a first conductive layer and a second conductive layer, a laminated filter in which a plurality of core materials and dielectric layers are alternately laminated, and a through hole pierces therethrough from a lowermost conductive layer provided so as to be in contact with the lowermost dielectric layer to the uppermost first conductive layer, a first surface dielectric layer provided above the laminated filter, and a first surface conductive layer provided above the first surface dielectric layer, the first surface conductive layer including a transmission line for a high-frequency signal and a ground GND.

摘要： A wireless communication system capable of dealing with weather that changes abruptly and capable of keeping communication quality at a certain standard or higher is provided. The wireless communication system comprises a first base station, and a second base station that performs communication mutually with the first base station. Each of the first base station and the second base station includes a transceiver unit being connected to an antenna for the communication, and a processing unit that controls the transceiver unit for the communication by referring to meteorological data in a place where the base station is located. The processing unit of the first base station, at a predetermined cycle, accumulates a set of meteorological data in a place where the first base station is located, and data on received electric power for the communication by referring to the meteorological data.
