1. Field of the Invention
The present invention relates to an antenna device, and more particularly to an antenna device for attaching onto various objects with magnetic members.
2. Description of the Prior Art
FIG. 1 is a perspective view of an antenna device in accordance with the present invention:
FIG. 2 is an exploded view of the antenna device;
FIG. 3 is a cross sectional view taken along lines
Referring to the drawings, and initially to FIGS. 1-5, an antenna device in accordance with the present invention comprises a seat 30 including an upper wall 31, and a chamber 32 formed therein and formed or defined by a peripheral wall 33. The seat 30 further includes a peripheral recess 34 formed in the upper portion thereof for receiving a sealing ring 35 therein, and includes one or more hubs 36 extended upward from the upper wall 31 thereof, and includes one or more orifices 37 formed in the hubs 36 respectively and formed through the upper wall 31 thereof, and includes one or more screw holes 38 formed therein.
An antenna member 20 includes a base 21 having a cone shape or frustum shape, and having a lower peripheral portion 22 engaged onto the upper wall 31 of the seat 30 and/or engaged onto the sealing ring 35 which may make a water tight seal between the base 21 of the antenna member 20 and the seat 30 (FIG. 3). The antenna member 20 includes an extension 23 extended from the base 21, and includes one or more studs 24 extended inward of the inner space 25 of the base 21. The extension 23 may be formed into different lengths (FIGS. 1, 7). One or more fasteners 26 may engage through the orifices 37 of the hubs 36 and may be threaded to the extensions 23 for securing the antenna member 20 to the seat 30.
A circuit board 40 is disposed on top of the upper wall 31 of the seat 30, and includes one or more notches 41 formed therein for receiving the hubs 36 and for preventing the circuit board 40 from rotating relative to the seat 30. One or more light devices 42 (FIGS. 1-3 and 6-11), such as the light emitting diodes 42 may be attached to the circuit board 40 for generating warning lights or decorative lights. One or more solar cells or the other batteries 47 may be provided and attached to the circuit board 40 for energizing the light devices 42.
