A hybrid antenna unit includes a circuit board having top and bottom surfaces, a planer antenna element which is mounted on the top surface of the circuit board and which receives first and second radio waves, an antenna base and a top cover that cover the circuit board and the planer antenna element. A bar antenna element stands on the top cover in a slanting position. A processing unit is mounted on the bottom surface of the circuit board and is connected to the planer antenna element. The processing unit processes the first and the second radio waves. A shielding case is mounted on the bottom surface of the circuit board and shields the processing unit. A booster circuit is mounted on the circuit board and is for use in the bar antenna element.

A hinge portion is formed on the base portion. An antenna portion is attached to the hinge portion so as to be pivotable thereabout. The hinge portion includes a hinge base having a first shaft formed on one end thereof, a second shaft formed on the other end thereof, and a first protrusion formed on an outer periphery of the second shaft, and a hinge bush rotatably mounted on the first shaft and engaged with the antenna portion. The antenna portion is formed with a hole surrounding the outer periphery of the second shaft. A projection is formed on an inner periphery of the hole. The first protrusion is brought into contact with the projection when the antenna portion is pivoted so as to define a predetermined angle with respect to the base portion.

A shield cover is disposed so as to be opposed to a bottom plate and electromagnetic-shields a signal processing circuit mounted on a rear surface of a circuit board. The shied cover has a ceiling portion which includes a mounter vacuumed portion disposed in a center portion of the ceiling portion and vacuumed by a vacuum nozzle of a mounter, a ring-shaped outer edge disposed from an end of the side wall portion inwardly, and a plurality of beam portions joining the mounter vacuumed portion to the outer edge. An electromagnetic shielding of the signal processing unit is carried out using both of the shield cover and the bottom plate.

A pole-type antenna unit has an pole-type antenna body having a cylinder extending up and down, a clip member, a universal joint for movably coupling the antenna body to the clip member. The clip member has an extending portion for extending from a bottom portion of the clip member, a ball joint provided to a tip of the extending portion, a half-cylinder mounted on the cylinder, and a grasping portion, fixed on the half-cylinder, for grasping the ball joint. The universal joint further has a non-slip ring-shaped packing disposed between the ball joint and the grasping portion. The grasping portion is fixed on the half-cylinder toward a lower position from a central portion thereof.
