This chapter presents an antenna which is reconfigurable at different frequencies and it is preferred for 5G communications with allowable reconfigurable radiations. The operational characteristics of the proposed design are examined practically using an FR4 substrate which is nonflexible and simulation is done using HFSS. The structure has mainly three switches, out of which the operating bands of the antenna are controlled by one lumped switch and the other two switches control the antenna beam switching. The beam of the antenna can be switched by controls 2 and 3. The designed tunable antenna is of size 23 × 25 × 1.6 mm3 and functions at 6.125 GHz and 8.6 GHz when the first switch is set in motion, veiling bands from 5.28 to 7.0 GHz and 8.0 to 9.0 GHz, accordingly. However, during the cut-out condition of the first switch, the antenna radiates at 4.8 GHz veiling 4.32–5.28 GHz. Switches 2 and 3 are always in the ON state. The prototype supports switchable microwave frequencies and applications, including 5G cellular phone bands. It is extremely light and compact.

摘要

This chapter presents an antenna which is reconfigurable at different frequencies and it is preferred for 5G communications with allowable reconfigurable radiations. The operational characteristics of the proposed design are examined practically using an FR4 substrate which is nonflexible and simulation is done using HFSS. The structure has mainly three switches, out of which the operating bands of the antenna are controlled by one lumped switch and the other two switches control the antenna beam switching. The beam of the antenna can be switched by controls 2 and 3. The designed tunable antenna is of size 23 × 25 × 1.6 mm3 and functions at 6.125 GHz and 8.6 GHz when the first switch is set in motion, veiling bands from 5.28 to 7.0 GHz and 8.0 to 9.0 GHz, accordingly. However, during the cut-out condition of the first switch, the antenna radiates at 4.8 GHz veiling 4.32–5.28 GHz. Switches 2 and 3 are always in the ON state. The prototype supports switchable microwave frequencies and applications, including 5G cellular phone bands. It is extremely light and compact.
