Abstract: A mobile wireless device includes a first microphone that receives an audio signal, a plurality of antennas disposed at different distances from the first microphone, a wireless unit that performs wireless signal processing for signals received/transmitted through the antennas, an antenna switch that is connected to the wireless unit and performs antenna switching to connect one of the plurality of antennas to the wireless unit, an audio signal processor that processes the audio signal, and a main body that is wearable and includes the wireless unit, the first microphone, the antenna switch, the audio signal processor, and at least one of the antennas. The audio signal processor calculates a level of the audio signal. The antenna switch performs the antenna switching based on the level of the audio signal to switch to one of the antennas that is anticipated to provide better performance.

Abstract: A radar apparatus includes an antenna composed of an end-fire array antenna and including a plurality of antenna elements; and a circuit board in which the plurality of antenna elements is disposed side by side in a first direction. At least one of the plurality of antenna elements is parallel to a substrate surface of the circuit board. A directivity of at least one of the plurality of antenna elements is set to a third direction tilted with respect to the first direction and a second direction orthogonal to the first direction.
