Abstract
Antenna structures and methods of operating the same are described. One apparatus includes a radio frequency (RF) circuitry, a housing, an antenna structure, and multi-connector switching circuitry. The RF circuitry includes a first RF feed for a first frequency and a second RF feed for a second frequency. The housing includes a first strip element disposed at a periphery of the housing, where the first strip element is physically separated from the housing by a first cutout in the housing. The antenna structure includes the first strip element with a first connector, a second connector, and a third connector coupled to the multi-connector switching circuitry. The multi-connector switching circuitry connects the first RF feed coupled to the first RF feed and the second RF feed where the first switching circuit to connect the first strip element to the first RF feed in a first mode of the first multi-connector switching circuitry.
