  • Patent number: 10090590
    Abstract: Apparatus and methods for enhanced antenna port isolation are disclosed. In one embodiment, a spatially compact patch antenna apparatus is disclosed. A plurality of walls are incorporated into the antenna assembly's bottom cover. The walls are located under the radiating element located on a top cover of the antenna assembly. The walls are in one implementation oriented orthogonally with respect to one another, and are placed adjacent to respective antenna feeds. The walls are then at least partly metallized using, for example, a laser direct structuring (LDS) process, and are further connected to a ground plane of an external substrate. By incorporating the metallized wall structures on the existing plastic structure of the bottom cover, isolation between the antenna ports is improved without requiring installation of additional components, use of slots in the ground plane, or increased physical separation (i.e., distance). Manufacturing cost and consistency are also advantageously improved.

  • Patent number: 10069209
    Abstract: Capacitively coupled antenna apparatus and methods of operating and adaptively tuning the same. In one embodiment, the insertion loss component in “beside the hand/head” use scenarios is significantly reduced or eliminated such that the antenna experiences only absorptive losses (which generally cannot be avoided), and a very small insertion loss by the host device radio frequency tuner. The exemplary antenna apparatus may be configured for multi-band operation, and also has a very small form factor (e.g., 3 mm ground clearance only at the bottom of the PCB, 4 mm height in one implementation), thereby allowing for use in spatially compact host devices such as slim-line smartphones, tablets, and the like. The adaptive antenna arrangement (using capacitive feed) can be tuned such that the tuner is used in free space, and the user's hand/head tunes the antenna to the band of interest while in use.

  • Patent number: 9774934
    Abstract: Low-profile electronic component apparatus and methods of manufacturing and utilizing the same, for use with low-profile mobile devices and other applications. In one embodiment, the mobile device comprises a wireless-enabled smartphone, tablet, or laptop computer, and the component comprises an audio speaker which is recessed into a metallic support element, the latter recessed into the mobile device outer housing. The support element is coated with an insulating material, and conductive traces formed thereon for electrical interface with the contacts of the speaker. When assembled, the installation results in a substantially reduced overall vertical profile, thereby both potentially reducing the overall required thickness of the host device, and creating additional volume within the device housing (such as for other components, and/or enhanced audio response of the speaker) resulting in an additional spacing between the speaker component and any extant antenna assemblies.

In an exemplary implementation, there is an adjusting point is provided from which a conductor is branched to an adjusting circuit. The adjusting circuit comprises a switch and alternative reactive elements connected to ground, selectable by the switch. When a reactive element is changed, the electric length and resonance frequency of the radiator change, and the corresponding operating band shifts. If the antenna is configured as a dual-band antenna, the above-mentioned operating band is the lower band. One or more higher operating bands are based e.g. on radiating slots implemented by the same radiator conductor. The operating band of the exemplary embodiment of the antenna below the frequency 1 GHz can be shifted in a wider range than in the corresponding known antennas.
