1. A multiband antenna having at least a lower operating frequency band and an upper operating frequency band, the antenna comprising:

  • a dielectric element having a first dimension;

    a conductive coating deposited on the dielectric element, the conductive coating having a first portion and a second portion, wherein said first and second portions are formed substantially parallel to each other along said first dimension;

    a feed structure, comprising at least a first and a second feed points, said feed structure coupled to the conductive coating; and

    a nonconductive slot formed between the first and second portions along said first dimension;

    wherein said slot is configured to form a quarter wave resonator in said upper operating band; and

    wherein said first and second portions cooperate to form a quarter wave resonator in said lower operating band.
