1Quantity of substance
If electromagnetic waves are transmitted through free space at millimeter wave frequencies, then bandwidth capacity is increased, but signal loss increases significantly
Solution Approach 1:
A dielectric waveguide coupler serves as an intermediary component that couples electromagnetic waves from free space onto a transmission medium (such as a wire or cable). The coupler enables the wave to transition from air propagation to guided propagation along the transmission medium, which supports millimeter wave frequencies with lower loss and provides alternative connectivity options for base stations and distributed antenna systems.
2Area of stationary object
If traditional wireless infrastructure is used to provide additional mobile bandwidth, then network coverage area is maintained, but data transmission efficiency decreases in urban areas with high demand
Solution Approach 1:
The system segments the transmission path into two distinct sections: free space propagation for coverage area extension and guided wave propagation along transmission media for efficient data transmission. By dividing the transmission into these two modes, the system maintains network coverage while achieving higher data transmission efficiency in urban areas with high demand.
3Loss of energy
If guided wave propagation is used along transmission media, then signal loss is reduced, but implementation complexity increases due to coupling requirements
Solution Approach 1:
The dielectric waveguide coupler acts as a specialized intermediary device that simplifies the coupling process between free space electromagnetic waves and transmission media. By using a dielectric waveguide structure, the coupler provides a straightforward implementation method that reduces signal loss while avoiding the need for complex coupling mechanisms.
