A Low-Sidelobe Millimeter-Wave Array Antenna Based on Textiles

A millimeter-wave array antenna with low sidelobes for 5G applications is presented. The antenna is fabricated using laser cutting technology on a textile material, providing excellent structural flexibility and high manufacturing precision. To achieve high gain, a narrow beamwidth and improved directivity, the design incorporates a serially-fed, eight-element microstrip Chebyshev linear array antenna (LAA). A study of structural deformation under bending along both the 0° directions is conducted to ensure mechanical stability. The textile array antenna features a low profile, suppleness, and cost-effectiveness, which is a candidate for potential mobile communications applications.
