Patent number: 10802139Abstract: An antenna apparatus has an antenna unit. The antenna unit transmits or receives a probe wave made of an electromagnetic wave. A magnet is disposed at a location through which the probe wave to be received by the antenna unit passes. The magnet works to generate a magnetic field along a direction in which the probe wave propagates. A polarizing filter is arranged on an opposite side of a magnetic body to the antenna unit. This minimizes the interference between an emitted wave and a reflected wave created by a cover, such as a bumper, regardless of the configuration of the cover.Type: GrantFiled: July 11, 2016Date of Patent: October 13, 2020Assignee: DENSO CORPORATIONInventors: Kazumasa Sakurai, Kazushi Kawaguchi, Toshiya Sakai, Yuji Sugimoto, Asahi Kondo

Publication number: 20180267138Abstract: A radar device is equipped with a radar emitting section, a radar input section, a detector, and a cover. The radar emitting section radiates an electromagnetic wave. The radar input section receives a return of the electromagnetic wave from an object. The detector works to detect the object using the return of the electromagnetic wave inputted to the radar input section.

Patent number: 10050348Abstract: An antenna device 1 has a dielectric substrate 2, a patch antenna 5 and electric power absorbing passive elements 21, 24 formed on a surface of the dielectric substrate. Each electric power absorbing passive element 21, 24 is formed between the patch antenna 5 and an edge portion in a polarized wave direction of the dielectric substrate 2. The electric power absorbing passive elements 21, 24 absorb a part of electric power received by the patch antenna 5. This makes it possible to suppress a surface current flowing to the edge portions of the dielectric substrate on a conductive plate (a front-surface conductor plate 3 or a back surface conductor plate 4) on the dielectric substrate.Type: GrantFiled: December 11, 2013Date of Patent: August 14, 2018Assignee: DENSO CORPORATIONInventors: Kazushi Kawaguchi, Yuji Sugimoto, Masanobu Yukumatsu, Asahi Kondo
