Method for mounting patch antenna
First Claim
Patent Images
1. A printed circuit board having a surface containing one or more patch antennas:
- said one or more patch antennas formed from sheet metal in a predetermined planar configuration with generally diametrically opposed fold down tabs that are bent perpendicular to said planar configuration, and each terminating at an end portion engaged with said printed circuit board proximate the location on said printed circuit board surface of each of said patch antennas;
each of said end portions of each of said fold down tabs extend generally parallel with said planar configuration of said patch antenna and contact said surface of said printed circuit board; and
, means securing each of said end portions of said fold down tabs to said printed circuit board so that said planar configuration is generally parallel to said surface of said printed circuit board to define said patch antenna.

3. A process for manufacturing a printed circuit board containing one or more patch antenna structures comprising the steps of, irrespective of sequence:
-
providing one or more patch antennas, each formed from sheet metal and having a predetermined planar configuration and a plurality of fold down tabs that have each been bent perpendicular to said planar configuration and terminate at an end portion for engagement with said printed circuit board;
providing a printed circuit board having a surface containing one or more locations for said patch antenna;
positioning one or more patch antennas relative to said printed circuit board surface in each location for said patch antenna on said printed circuit board in a manner where said end portions of said fold down tabs contact said printed circuit board;
said end portions of said fold down tabs are formed to extend generally parallel with said planar configuration of said patch antenna; and
,securing said end portions of said fold down tabs of each patch antenna to said printed circuit board at a predetermined distance of said planar configuration of said patch antenna from said surface of said printed circuit board to define said patch antenna on said printed circuit board. - View Dependent Claims (4, 5)
said securing is accomplished by (SMT), standard surface mount technology.
