摘要:
An antenna device includes an antenna, the antenna including an antenna element, a circuit board, and a planar metallic holder disposed between the antenna element and the circuit board. The antenna device further includes an antenna case accommodating the antenna, and the antenna case include a top cover and a bottom plate serving as a base. The metallic holder supports the antenna element on the base, and includes a flat-shaped portion mounting a bottom surface of the antenna element and a plurality of tabs extending upwards from peripheral edges of the flat-shaped portion. The plurality of tabs includes a pair of front tabs and a pair of rear tabs, and a distance between the pair of front tabs is shorter than a distance between the pair of rear tabs.

A complex antenna device includes: an antenna base having a main surface and first and second ends opposed to each other; a bar antenna including a metal body and disposed upright on a side of the first end of the antenna base; at least one planar antenna mounted on the main surface of the antenna base between the first and second ends of the antenna base; a metallic member provided on a side of the second end of the antenna base so as to substantially remove physical influence of the bar antenna on the planar antenna.

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.
