Abstract

Disclosed is a glass antenna wherein two antennas, which are formed on a glass surface and have different receiving frequency bands, are integrated. In the glass antenna (30), the glass surface (10) includes a first antenna pattern (31), which is composed of one perpendicular conductive body (310) and a plurality of horizontal conductive bodies (311-316) orthogonally intersecting the perpendicular conductive body, and a second antenna pattern (32), which has a receiving frequency band different from that of the first antenna pattern and is composed of one horizontal conductive body (320) capacitively coupled with the first antenna pattern. One discretionary horizontal conductive body among the plurality of horizontal conductive bodies of the first antenna pattern is connected to a power feed point (20) by means of a connecting conductive line (40). Signals received by the first antenna pattern or the second antenna pattern are amplified by means of a shared amplifier (50).

Description

technical field

[0001] The present invention relates to a glass antenna having an antenna pattern and a feeding point for feeding the antenna pattern formed on a glass surface. Background technique

[0002] The glass antenna in which the antenna conductor is formed on the rear window glass of the vehicle has no protruding part in design compared with the conventional rod antenna, so it is superior in appearance. Furthermore, glass antennas are widely used because they are less likely to be broken and do not generate bagpipe noise.

[0003] On the other hand, glass antennas equipped with AM / FM antennas are also popular. For example, Patent Document 1 discloses a glass antenna in which a high-frequency choke coil is inserted between a bus bar constituting a defogging heater and ground, and the defogging energized heating heater can be used as an antenna.

[0004] if based on Figure 15 The glass antenna disclosed in Patent Document 1 will be described as follows.
