    • An auxiliary antenna for a RF communicating computing device such as a smartphone or pad computer or laptop computer, is provided for enhancement of the RF transmit and receive capabilities of the computing device. The antenna is engaged using mutual coupling of the antenna to an input point or feed line or antenna element of the computing device by registered placement on or adjacent an exterior surface of the computing device. The registered engagement can be provided by inclusion of the auxiliary antenna in a protective or decorative surrounding case, or use of an applicable antenna on a dialectic and a pattern configured to only engage the proper surface of the computing device.

    • A radiator element for transmission and reception of RF communications formed of a planar conductive material positioned upon a planar dielectric substrate surface. Two lobes formed of the conductive material have side edges abutting a cavity decreasing in cross section between the lobes. The cavity has a widest point configured to receive RF frequencies at the lowest frequency and a narrowest point configured to receive a highest frequency of the element. The widest and narrowest point may be changed during manufacture to fit the frequency spectrum needed. Opposing pairs of recess cavities formed in the side edges of the lobes along the decreasing edges of the cavity enhance the frequency of operation for frequencies paired to the distance between the pairs of notches. Projections are employable along the side edges to optimize impedance.
    • 用于发射和接收由位于平面电介质基片表面上的平面导电材料形成的RF通信的散热元件。 由导电材料形成的两个凸角具有邻接在凸角之间横截面减小的空腔的侧边缘。 空腔具有被配置为以最低频率接收RF频率的最宽点,并且被配置为接收该元件的最高频率的最窄点。 在制造过程中,最宽和最窄的点可能会发生变化,以适应所需的频谱。 沿着腔的下降边缘形成在凸角的侧边缘中的相对的凹槽对增加了与成对的凹口之间的距离成对的频率的操作频率。 投影可以沿侧边使用,以优化阻抗。
