Here we take a look at whats involved in building a DIY Homebrew Patch Antenna for L Band/Inmarsat.
Reflector Size: 170 mm x 170 mm
Patch Size: 94 mm x 94 mm
Corner Trim: 21 mm from top right and bottom left corners
Coax Connection (Probe): 24 mm from top edge
Height of patch from reflector: 7 mm
The corners of the patch need to be trimmed to give the patch antenna right hand circular polarization (RHCP), which is the polarization used by Inmarsat Satellites.
