1. A compact electronic device comprising:
a housing;
circuitry; and
a first antenna and a second antenna connected to the circuitry and contained in the housing, the first antenna being connected at a proximal end to a grounding plate, the second antenna being connected at a proximal end to the grounding plate, the first antenna and the second antenna being angled relative to one another, such that a distal end of each of the first antenna and the second antenna are physically spaced closer to each other than the proximal ends of the first antenna and the second antenna; wherein the first antenna and the second antenna are each located on adjacent sides of the housing from one another, and further comprising one or more additional antennas located on opposite sides of the housing from the adjacent sides.
