The entire contents of each of the aforementioned patent applications are hereby incorporated by reference into this specification and become part of this specification. The disclosure relates to wireless signal technology, and in particular, to a wireless signal device and a wireless signal detection method. Wireless signal technology has been developed over the years. Depending on the type of transmitted signal, wireless signals include pulse signals and continuous wave signals. Due to the rapid advancement of technology, frequency modulated continuous wave (FMCW) signals have recently been widely used in various fields. For example, FMCW signals are applied in the touch field for gesture detection. However, current gesture detection suffers from poor recognition accuracy, and there is still room for improvement. A wireless signal device and a wireless signal detection method capable of effectively improving the accuracy of touch detection are provided in the disclosure. The wireless signal device of the disclosure includes an antenna device, a transmitting circuit, and a receiving circuit. The antenna device is configured to form a narrow-beamwidth antenna radiation pattern. The antenna device includes a transmitting antenna array and a receiving antenna array. The transmitting antenna array is arranged within a first plane and is configured to transmit a transmitting signal. The receiving antenna array is arranged within a first plane and is configured to receive a reflected signal, the reflected signal being generated by the transmitting signal being reflected by an external object. The transmitting circuit is configured to generate a transmitting signal. The receiving circuit is configured to generate an internal signal based on the reflected signal, the internal signal being related to spatial information of an external object. The narrow-beamwidth antenna radiation pattern forms a flattened detection area, the flattened detection area forms a second plane, and the first included angle between the first plane and the second plane is 80 degrees or more and 100 degrees or less. The wireless signal device is configured to detect spatial information of an external object within a flattened detection area, and the spatial information includes only two-dimensional spatial information within a second plane. A method for detecting a wireless signal is also provided in the disclosure. The wireless signal detection method comprises the following operations: a narrow beamwidth antenna radiation pattern is formed, wherein the narrow beamwidth antenna radiation pattern forms a flattened detection area, and the flattened detection area forms a second plane. A transmission signal is transmitted. A reflected signal is received, wherein the reflected signal is generated by the transmission signal being reflected by an external object, and the external object is located within the flattened detection area. An internal signal is generated according to the reflected signal, wherein the internal signal is related to spatial information of the external object, and the spatial information comprises only two-dimensional spatial information within the second plane. Based on the above, the antenna device of the wireless signal device of the embodiment of the disclosure includes a transmitting antenna array and a receiving antenna array arranged within a first plane. The antenna device may form a narrow beamwidth antenna radiation pattern. The narrow beamwidth antenna radiation pattern may form a flattened detection area. The flattened detection area forms a second plane that is substantially perpendicular to the first plane. The wireless signal device may be configured to detect spatial information of an external object within the flattened detection area, wherein the spatial information includes only two-dimensional spatial information within the second plane. In this way, by using the antenna device to detect only two-dimensional spatial information of an external object within the flattened detection area in the second plane, the detection error in three dimensions caused by detecting three-dimensional spatial information can be reduced, thereby improving the accuracy of touch detection and reducing the amount of information calculation data.
