Described are an antenna system for wireless communication and a method of configuration thereof. The antenna system can include a first radiator having a first resonance frequency, a second radiator having a second resonance frequency different from the first resonance frequency, a first electromagnetic coupler associated with the first radiator and a first frontend, a second electromagnetic coupler associated with the second radiator and a second frontend, and a switch. The switch can be configured to connect the first electromagnetic coupler and the second electromagnetic coupler in an inter antenna aggregation configuration in a first mode of operation. The switch can also be configured to connect the first electromagnetic coupler and the second electromagnetic coupler in an intra antenna aggregation configuration in a second mode of operation.
