  • Patent number: 11862877
    Abstract: An antenna includes antenna elements provided one by one on the respective sides of a substantially rectangular conductor plate. Each of the antenna elements includes a feeding wire and a split ring conductor having a shape in which a ring is partially cut by a split part. The feeding wire is electrically connected to the split ring conductor and extends in a direction across a region formed inside the split ring conductor. Two antenna elements provided on two arbitrary sides facing each other of the conductor plate among the four antenna elements are each supplied with power through the feeding wire included in each antenna element so as to have substantially the same direction of an electric field in a polarization direction.

The second conductive member includes a first portion belonging to a first layer substantially parallel to a plane to which the first conductive member belongs, a second portion belonging to a second layer substantially parallel to the plane and facing the first layer, and a third portion electrically connecting the first and second portions. The third conductive member includes fourth and fifth portion respectively belonging to the first and second layers, and a sixth portion electrically connecting the fourth and fifth portions. At least parts of the first and fifth portions face each other in a direction substantially perpendicular to the plane.

  • Publication number: 20220029296
    Abstract: An antenna includes a conductor plate, for example. The conductor plate has a slot and a branch slot, wherein the branch slot has one end connected to the slot and another end which, when viewed from the one end, extends along the slot in an antinode direction of an electric field at the lowest-order resonant frequency of the antenna, and is closed in the conductor plate.

  • Patent number: 10979338
    Abstract: A method is disclosed for optimizing packet transmission paths in a mobile communication network (400) in which packets are transmitted and received between mobile stations (10-14) or between a mobile station and a fixed network (120) by way of a plurality of packet transmission device (60-64, 70-72, 80, and 81) and radio base stations (50-57). When a mobile station uses a service that is provided by a fixed network (300), imposed are applied on the packet transmission path such that packets pass by way of specific packet transmission devices (80 and 81) depending on the fixed network (external network) 300. When the mobile station uses a service that is provided by the mobile communication network (400), on the other hand, no restrictions are imposed on the packet transmission path, and the packet transmission path is thus set such that the link costs are a minimum.
