A flexible dual linear polarized H-shaped aperture coupled S-band array is presented. The array uses flexible polyimide printed circuit board (FPC) technology and polyethylene foam (PF-4). The antenna comprises an aperture FPC layer, two separate FPC layers for the feed networks of the orthogonal polarizations, and an FPC patch. These layers are separated by PF-4 foam to enable conformability.
The antenna is tested on a flat surface and conformed to cylindrical surfaces with radius of 200 mm,150 mm, and 100 mm. The measured antenna provides conformability, dual linear polarization, high impedance bandwidth (20-25%), and port isolation larger than 30dB.
