Abstract: An antenna module includes a first sub array to a fourth sub array. The first sub array to the fourth sub array have a rectangular substrate. Each of the first sub array to the fourth sub array includes a plurality of radiation electrodes disposed along an extending direction of a long side. The first sub array to the fourth sub array are configured to radiate radio waves of the first polarized wave to the fourth polarized wave, respectively. The first polarized wave is different from the second polarized wave, and the third polarized wave is different from the fourth polarized wave. The first polarized wave is the same as the third polarized wave, and the second polarized wave is the same as the fourth polarized wave.

Abstract: An antenna module includes a dielectric substrate having a multilayer structure, a radiating element, a feed wiring, a filter device, and a ground electrode. The dielectric substrate has a first main surface and a second main surface. The radiating element is formed on the first main surface of the dielectric substrate or in an inner layer than the first main surface. The feed wiring transmits a radio frequency signal to the radiating element. The filter device is arranged on the feed wiring. The ground electrode faces the radiating element and is arranged in a layer between the radiating element and the filter device. A recess is formed in the second main surface of the dielectric substrate. The filter device is arranged at a position that does not overlap with the recess when viewed in a plan view from a normal direction of the dielectric substrate.

Abstract: An antenna module includes a dielectric substrate, in or on which a feed element is formed, a dielectric substrate, in which a ground electrode (GND) is formed, and conductive members. The dielectric substrate is disposed opposite the dielectric substrate. When viewed in plan in the direction normal to the feed element, the conductive members are disposed around the feed element. An air layer is formed between the dielectric substrate and the dielectric substrate. The conductive members are formed in the air layer.

Abstract: An object of the present disclosure is to acquire information that can be used for trade area analysis. An information processing apparatus includes a storage and a controller. The storage stores travel information about a plurality of vehicles, the travel information including position information on a starting point and an end point of one trip. The controller extracts, from the storage, the travel information about a plurality of target vehicles with respect to which the end point of one trip is a predetermined target place. Furthermore, the controller specifies a starting point range that is a range where the starting point of one trip of each of the plurality of target vehicles is present.
