摘要： An RFID reader antenna (1) for use in an intelligent cabinet (2), such as a smart fridge, is disclosed. The antenna (1) is configured for operation within the UHF band and has omnidirectional radiation pattern and circular polarization. The antenna comprises a dielectric substrate (11), and a ground plane (12) provided on the dielectric substrate. An aperture (13) forms an open area within the bounds of the ground plane (12). A radiating element (14; 14′; 14″; 14′″; 14) is provided on the dielectric substrate in a plane parallel to the ground plane, and arranged within the open area, when viewed from a direction perpendicular to the ground plane (12), and surrounded by the ground plane.

摘要： A power tool may include a compartment in its housing and a first printed circuit board (PCB) located in the housing and electrically coupled to a first connector. An insertable wireless communication device may include a second electronic processor and an antenna that are each mounted to a second PCB. The insertable wireless communication device may be configured to be received in the compartment and may include a second connector configured to electrically and physically couple to the first connector. The insertable wireless communication device may be configured to wirelessly communicate with an external device. When the insertable wireless communication device is inserted into the compartment, a first conductive layer of the first PCB may be configured to be electrically coupled to the antenna via the first connector and the second connector such that the first conductive layer of the first PCB serves as a ground plane of the antenna.
