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.

Abstract: A compact multimode broadband antenna that supports collocated resonances with very little destructive interference occurring between resonant modes. The antenna comprises a monopole element and a folded loop element that partially share structure, and are fed via a unitary RF feed port. The antenna is well suited for simultaneous dual band WLAN applications and ultra-wideband operations.

Abstract: A plurality of UAVs may be operated in a fleet, each of the UAVs in the fleet being configured to work collectively to achieve one or more functions, such as to create a display or implement an antenna array. The fleet of UAVs may operate individually and/or may be coupled to one another to operate as a collective unit. In some embodiments, one or more UAVs in the fleet may operate individually, while two or more UAVs in the fleet may be connected to one another. In such embodiments, the individual UAVs and the connected UAVs may together comprise the fleet.
