Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
