A ‘Stitched’ Flexible Light Weight Multilayer 16x16 Antenna Array on LCP

چکیده
This paper presents a light weight multilayer 14 GHz antenna array on an organic LCP (Liquid Crystal Polymer) substrate. The antenna structure includes a two layer corporate feed network, which is partially embedded, connected with vias, otherwise known as ‘stitched’. First, using 4x4 microstrip patch arrays as the unit array, a 6.5 beam steer is observed when a 90 o phase difference is applied to a 4x8 antenna array. The stitched 4x8 antenna array has a 3 dB beamwidth of 12 and a maximum gain of 15.4 dB with no phase shift, and the gain drops to 13 dB with a phase shift. Next, a 16x16 antenna has been constructed applying the stitching concept. The results show a 3 dB beamwidth of 6 and a 16.8 dB of gain.
