COMMUNICATION DEVICE COMPRISING A RETROREFLECTIVE STRUCTURE

This abstract first appeared for US patent application 20250062528 titled 'COMMUNICATION DEVICE COMPRISING A RETROREFLECTIVE STRUCTURE

Original Abstract Submitted

the disclosure relates to suppressing surface waves in a communication device for a wireless communication system. the communication device includes a dielectric layer extending along a plane between a chassis and a glass layer, an antenna element configured to emit a radio wave, and a retroreflective structure extending inside the dielectric layer and being located adjacent to the antenna element, and where the retroreflective structure is configured to reflect the radio wave in an angle non-parallel to the plane. the retroreflective structure hence prevents parasitic channeling of the antenna energy into surface waves in and behind the glass layer and directs the radiation into the desired direction.
