An ultra wide band (UWB) device and a detect and avoid (DAA) method thereof are provided. The UWB device includes a detect and avoid (DAA) module block which detects a strength of radio signals received in a plurality of channels and determines communicability of the channels; a multitone generation block which generates a plurality of frequencies corresponding to the plurality of the channels and outputs one of the plurality of frequencies; and a controller which controls the multitone generation block to generate frequencies of an available channel which is determined to be communicable by the DAA module block. The method includes detecting a strength of radio signals received in a plurality of channels; determining communicability of the channels according to the detected strength of the radio signals; generating frequencies corresponding to a channel which is determined to be communicable; and transmitting or receiving a signal using the generated frequencies.

Ultra wide band device and detect-and-avoid method thereof

A multiple-input multiple-output (MIMO) antenna operable in a multiband includes a plurality of antenna elements each including a radiator radiating electromagnetic waves, a ground connected to the radiator, at least one switching element mounted in an area of lengthwise direction of the radiator and short-circuiting or opening the area of the radiator.
