Planar antennas on flexible substrate for wireless applications

Flex-circuits are a reliable alternative to conventional electronic products. It can offer the same advantages of a printed circuit board: repeatability, reliability, and high density. The design of a planar antenna on a flexible substrate can effectively supersede that of an antenna on a FR-4 substrate for more flexible applications on wireless system integration, such as RFID or Bluetooth link as well as in steering microwave beam.
