Vehicle roof glass antenna for reception of FM radio and TV broadcasting

摘要

The invention relates to an antenna attached to a vehicle roof glass, i.e. a glass plate fitted in an opening of the roof of a vehicle body, for receiving FM radio and TV broadcast waves in both the VHF band and the UHF band. Essentially the antenna is comprised of a main element which is combination of two linear segments each of which is a conductive strip attached to the roof glass, a feed point attached to the roof glass and a connection line which connects the main element to the feed point and extends parallel or nearly parallel to the longitudinal center axis of the vehicle body. The two linear segments of the main element extend respectively obliquely with respect to the aforementioned center axis and intersect each other. It is suitable that the two linear segments have the same length and bisect each other. Optionally the antenna may include an auxiliary element attached to the roof glass and connected to the feed point. For example, the auxiliary element may be a combination of two linear segments intersecting each other or an angled segment having at least one L-shaped portion.
