Antenna systems with a frequency range two antenna array integrated into a frequency range one antenna

A method of signal communication in a mobile device, the method comprising:

• transmitting a first radio frequency signal of a first frequency in the range of 6.125 gigahertz to 7.125 gigahertz using an antenna of an antenna system, the antenna having an outer perimeter;
• transmitting a plurality of second radio frequency signals of a second frequency that is greater than the first frequency using an antenna array of the antenna system, the antenna array formed directly on or in the antenna within the outer perimeter of the antenna, the second frequency being a fourth harmonic of the first frequency, and the antenna array including at least one planar inverted-F antenna embedded in the antenna;
• conditioning the first radio frequency signal using a first signal conditioning circuit connected to the antenna;
• and
• conditioning the plurality of second radio frequency signals using a plurality of second signal conditioning circuits connected to the antenna array.

An antenna system comprising:

• an antenna configured to transmit a first radio frequency signal of a first frequency in the range of 6.125 gigahertz to 7.125 gigahertz, the antenna having an outer perimeter;
• an antenna array formed directly on or in the antenna within the outer perimeter of the antenna, the antenna array configured to transmit a plurality of second radio frequency signals of a second frequency that is greater than the first frequency, the second frequency being a fourth harmonic of the first frequency, and the antenna array including at least one planar inverted-F antenna embedded in the antenna;
• a first signal conditioning circuit connected to the antenna and configured to condition the first radio frequency signal;
• and
• a plurality of second signal conditioning circuits connected to the antenna array and configured to condition the plurality of second radio frequency signals.
