Title: Helical antenna and method of modulating the performance of a wireless communications device

Patent ·
OSTI ID:1568283
; ;

A wireless communication device includes an array of helical antennas on a substrate. Each helical antenna comprises a strain-relieved sheet with a conductive strip thereon, where the strain-relieved sheet and the conductive strip are in a rolled configuration about a longitudinal axis. The conductive strip is oriented at an angle α with respect to a rolling direction so as to comprise a helical configuration about the longitudinal axis with a non-zero helix angle β. The array exhibits a maximum gain of at least about 10 dB at a working frequency of at least about 0.1 THz.
