Compact dual band antenna

An antenna system, comprising:

• a first antenna configured to resonate in a first frequency band, the first antenna comprising:
• a base element having a major dimension of less than about 5 millimeters, the base element operatively coupled to a signal trace;
• a cross element extending at least substantially orthogonally to the base element, the cross element electrically connected with the base element, the cross element having a major dimension of less than about 10 millimeters;
• a second antenna spaced from the first antenna and configured to resonate in a second frequency band, the second antenna comprising:
• a first member extending at least substantially parallel with the base element of the first antenna and alongside a first end of the cross element, the first member having a major dimension of less than about 10 millimeters, the first member electrically connected to a ground plane;
• a second member electrically connected with the first member and extending along the cross element and at least substantially parallel with the major dimension of the cross element of the first antenna, the second member having a major dimension of less than about 15 millimeters;
• and
• a third member electrically connected with the second member and extending at least substantially parallel with the first member and alongside a second end of the cross element opposite the first end, the third member having a major dimension that is less than the major dimension of the first member of the second antenna.

An antenna system formed by one or more layers of a Printed Circuit Board (PCB), the antenna system comprising:

• a first antenna element configured to resonate in a first frequency band centered at about 5.4 GHz;
• a second antenna element configured to resonate in a second frequency band centered at about 2.4 GHz;
• wherein the first antenna element and the second antenna element fit within a rectangular area of less than about 100 square millimeters on the PCB;
• and
• wherein the first antenna element has a bandwidth of at least 2 GHz and the second antenna element has a bandwidth of at least 100 MHz, wherein the bandwidth is defined as having less than a −10 dB return loss within the band.
