無線通信モジュール
Document Type and Number:
Japanese Patent JP6384550
Kind Code:
B2
Abstract:
First and second end-fire antennas are arranged on a dielectric substrate. The first end-fire antenna has polarization characteristics being parallel with a first direction. The second end-fire antenna has polarization characteristics being parallel with a second direction orthogonal to the first direction. A patch antenna provided with a first feed point and a second feed point, which are different from each other, is arranged on the dielectric substrate. When the patch antenna is fed from the first feed point, a radio wave whose polarization direction is parallel with the first direction is excited. When the patch antenna is fed from the second feed point, a radio wave whose polarization direction is orthogonal to the first direction is excited. A wireless communication module capable of achieving directivity in a wide range from a direction parallel with the substrate to the direction of the normal to the substrate is provided.
