Antenna configurations for compact device wireless communication
View Patent ↗A wireless communication device is configured to provide wireless communication to a host device when disposed in a mated position with the host device such that a housing of the wireless communication device extends a distance Lid from a face of the host device. The wireless communication device includes a transceiver, a controller in communication with the transceiver, and a modem in communication with the controller. The wireless communication device also includes a dipole antenna having a dipole effective current axis Ix for a selected wavelength λ in the mated position that is at a distance from the face of the host device that is in the range of about 0.09λ to about 0.25λ.
