- Lightweight Conformal Filtering Antenna Based on Stacking of Multi-Corrugated Polyimide Films
A lightweight and stacked conformal filtering antenna is demonstrated using copper-cladded polyimide films (CCPF). The antenna consists of primary, secondary, and parasitic patches as rectangular stubs using multi-corrugated polyimide films to improve bending performance. Good filtering performance is obtained by stub-loading of parasitic elements attached to both ends of the primary radiator. Bandwidth (BW) enhancement is achieved by stacking of corrugated polyimide films combined with nylon spacers, forming a five-layer antenna design. For the flat case, the antenna has a BW ranging from 1.17 GHz to 1.38 GHz (16.5%) and nearly flat gain response with a maximum gain of 8.6 dBi at 1.29 GHz. The antenna is fabricated and measured for the flat case and conformed to cylinders with radii Rc200 mm,160 mm,100 mm,80 mm, and 40 mm.
