Fiber Lens Based Optical Antenna Design for OWC With Full Beam Coverage
In infrared optical wireless communications, narrow beams require the perfect calibration of the base station (BS) and user terminal (UT), which cannot support multiple moving users. This paper proposes a fiber lens based optical antenna, which employs a

Beam scanning one-dimensional leaky-wave antenna
Although the beam of a leaky-wave antenna (LWA) scans with frequency, steering through the broadside is usually challenging. Various methods have been developed to overcome this limitation.
