Multiple PIFA/IFA type antennas operating at the same frequency including short pins to minimize antenna separation

An antenna system includes a plurality of PIFA/IFA type wherein each of the plurality of antennas have either a same short pin or different short pins located together to minimize antenna separation between the plurality of antennas. The antennas share the same short pin with the width between at least two antennas of the plurality of antennas designed to minimize coupling when the at least two antennas operate at a same frequency. The short pin width is at least λ/8 where λ is based on a lowest frequency of operation of the antenna system, the lowest frequency of operation is about 2.4 GHz. The common short pin also includes a minimum distance to the associated antenna feed. Where the different short pins are located together the antenna includes a first short pin as a cylinder and a second short pin located within the cylinder without contact therebetween.
