1. An antenna structure comprises:

  • a first antenna having a first geometry corresponding to a first frequency;

    a second antenna having a second geometry corresponding to a second frequency, wherein the second antenna is proximal to the first antenna, and wherein the second antenna utilizes electrical-magnetic properties of the first antenna to transceive signals at the second frequency;

    a third antenna having a third geometry corresponding to a third frequency, wherein the third antenna is proximal to the first antenna, and wherein the third antenna utilizes electrical-magnetic properties of the first antenna to transceive signals at the third frequency; and

    a fourth antenna having the second geometry corresponding to the second frequency, wherein the fourth antenna is proximal to the first antenna and has a different polarization than the second antenna, and wherein the fourth antenna utilizes the electrical-magnetic properties of the first antenna to transceive the signals at the second frequency.
