Optically induced electron-hole plasmas in silicon are used to perform radiation pattern tuning. The antenna is a slot loaded microstrip patch and the effect of illumination is shown to produce beam switching in the radiation patterns of certain modes while other modes are left unaffected. The structure is specifically designed to make the best use of currently available miniature laser sources...

In this paper, another thick dielectric (DD) fix cluster radio wire model working at 28 GHz for future fifth generation (5G) cell systems is exhibited. This cluster radio wire is proposed and planned with a standard printed circuit board procedure to be reasonable for combination with radio recurrence/microwave hardware. The proposed structure utilizes four round molded DD fix radiator radio wi...

Abstract Recently, graphene-patch antennas have been widely used in communication technology, especially THz applications due to the extraordinary properties of graphene material. Herein, a graphene-based rectangular microstrip patch antenna is designed on an FR4 substrate material (ɛ r = 4.3). A single and double-faced superstrate MTM placed upon radiating for di erent purposes, such as enhanc...
