A receiving module is fixed in the internal space formed by a pair of case parts. The receiving module includes a dielectric substrate, an antenna element provided on one main surface of the dielectric substrate, a ground plate provided on the other main surface of the dielectric substrate, and a circuit board provided on the backside of the main surface having the dielectric substrate at the ground plate, and a shield case that shields the circuit board. The ground plate has an extension extending parallel to the antenna element from the outer peripheries of said dielectric substrate and the circuit board, and the extension is supported in the pair of the case parts, so that the receiving module is fixed in the internal space of the pair of case parts.
SUMMARY OF THE INVENTION The present invention has been made in view of the above described circumstances associated with the conventional technique, and it is an object of the invention to provide a satellite radio receiving antenna that can suitably be provided in a vehicle and a satellite radio receiving system using such a satellite radio receiving antenna.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic, exploded perspective view of a satellite radio receiving antenna to which the invention is applied; and
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Now, an embodiment of the invention will be described in detail in conjunction with the accompanying drawings. In the following, a satellite radio receiving antenna 10 (hereinafter simply as �receiving antenna 10�) as shown in FIGS. 1 and 2 will be described as an application of the invention.
As shown in FIGS. 1 and 2, the receiving antenna 10 has a case main body formed by joining a pair of case parts 11 a and 11 b made for example of a resin material. In this embodiment, the case part 11 a is in a bowl shape, and the other part 11 b is in a plate shape. The case part 11 b has a plan view shape corresponding to an opening formed at the bottom of the case part 11 a, and the pair of the case parts 11 a and 11 b are made into an integral form as a projection 26 is fitted with a receiving part 27, so that the main body case 11 is formed. Note that while the main body case 11 may have an arbitrary outer size, the size is 100 mm�80 mm�100 mm in this embodiment.
The ground plate 23 made of a conductive material such as a metal extends parallel to the antenna element 22 beyond the outer peripheries of the dielectric substrate 21 and the circuit board 24. In this embodiment, the extended part of the ground plate 23 is referred to as extension 23 a. The dielectric substrate 21 has a pin hole (not shown) through the dielectric substrate 21 immediately below the position of the antenna element 22. A pin (not shown) that electrically connects the antenna element 22 and the ground plate 23 is inserted through the pin hole.
The circuit board 24 has an amplification circuit or the like that amplifies signals from the satellite received by the planar antenna including the antenna element 22, the dielectric substrate 21, and the ground plate 23. The circuit includes various electronic elements and a semiconductor chip. The circuit board 24 is connected with a signal line 30. The signal line 30 is extended externally from the main body case 11 through a hole for signal line extension formed at the case part 11 a. The receiving module 20 described above has the extension 23 a of the ground plate 23 supported between the projection 26 and the receiving part 27 of the pair of the case parts 11 a and 11 b, so that the receiving module is fixed in the internal space of the main body case 11. The module is adhered to a windowpane 40 for example with an adhesive sheet 31 and thus provided in the vehicle.
