Dual band simultaneous or DBS means that a smartphone can use both the bands - 2.4GHz and 5GHz at the same time.

Second method includes construction of a transformerless BP prototype network and single transformation step on this prototype to result in
dual band filter characteristic.

Reconfigurable multiband antenna demonstrated in some papers can be switched from single narrowband to another single narrowband [4], between
dual band to another
dual band [5] and multiband to other multiband configurations [6].
