However, these printed wire antennas are too lossy for high frequency operation of 4G / LTE (700-3800MHz), GNSS (1150MHz-1610MHz multi-band), WiFi and DSRC (2400MHz-6000MHz multi-band), let alone 77GHz car radar

Abstract

The present application generally relates to antennas embedded in or on glass structures. More specifically, the application teaches an apparatus extending a ground plane on an antenna proximate to a dielectric structure, such as a windshield, in order to couple a radiated wave into the dielectric structure in order to control the tilt of the radiation pattern of the antenna.

Description

technical field [0001] The present application generally relates to antennas embedded on glass structures. More specifically, the present application teaches a surface mount antenna mounted to a dense dielectric material such as a windshield in a manner that controls radiation to lower elevation angles. Background technique [0002] The glass structure is a convenient location for mounting antennas and other conductors. Glass structures are non-conductive and provide designers with a greater variety of radiation patterns and directionality. Over the past few decades, the use of radio frequency (RF) in automobiles has increased, including today's AM / FM radios, GNSS, 4G / LTE, satellite radios, remote keyless entry, dedicated short-range communication (DSRC) radios, WiFi , tire pressure monitors and automotive radar. While some RF systems can share an antenna, in general each RF system requires a separate antenna. Some RF services require multiple antennas, for example 4G ha...
