In example implementations, an antenna for a mobile device is provided. The antenna includes a printed circuit board and a plurality of metal members coupled to the printed circuit board. The printed circuit board is devoid of metal traces. The plurality of metal members is positioned along a length of the printed circuit board to operate at a desired frequency band when inserted into an opening along an outer edge perimeter of a metallic housing of the mobile device.

Invisible antennas

Examples disclosed herein relate to a dual band antenna in a mobile device having a peripheral conductive member. In one example, the dual band antenna includes a multilayer PCB having a first antenna feed trace, a second antenna feed trace, a ground trace, and a connecting trace disposed on a dielectric substrate. The connecting trace may couple the first antenna feed trace, the second antenna feed trace, and the ground trace. Further, the dual band antenna includes a connecting element to couple to the connecting trace with the peripheral conductive member to form an integrated resonant element.

Dual band antenna with integrated conductive bezel

Example implementations relate to mixed mode slot antennas. Mixed mode slot antennas may be implemented in a display housing of a communication device. A mixed mode slot antenna unit may include a first PCB attached to a first metal layer to form a first mode antenna, where the first metal layer includes a first slot, and the first metal layer is a metal back cover of the display housing of the communication device. The mixed mode slot antenna unit may also include a second PCB coupled to the first PCB to form a second mode antenna, where the second metal layer includes a second slot, and where the second metal layer is a metal front cover of the display housing; and a non-conductive layer disposed between the first PCB and the second PCB to provide insulation between the first PCB and the second PCB.

Mixed mode slot antennas

In one example, a dual-band wireless LAN antenna. The antenna includes plural antenna traces disposed in a first plane that is substantially parallel to, and spaced apart from, a plane of electrically conductive material. At least two of the traces are dimensioned to resonate at different frequencies. The antenna also includes a decoupling element disposed in a second plane between the first plane and the conductive plane. The decoupling element is electrically connected to a selected one of the antenna traces. The antenna further includes a conductor which is electrically connected to the decoupling element and to the conductive plane.
