    Abstract: Example implementations relate to adjusting radiofrequency transmission power of antenna devices consistent with the disclosure. For example, a non-transitory machine-readable medium storing instructions executable by a processing resource to transmit a signal using a first transmission power to query an environment surrounding an antenna device to determine whether an object is causing path loss along a communication link, and adjust a transmission power of the antenna device to a second transmission power based on a determination that an object is causing path loss along the communication link.

    Abstract: Flexible printed antenna devices, methods, and systems are described herein. One device includes a conductive element having a pattern of printable conductive ink applied onto an ink-receptive, non-conductive substrate to form an antenna having multiple antenna elements, wherein the substrate is flexible allowing the multiple antenna elements to be rolled or folded over on each other and a connector element formed from a pattern of printable conductive ink applied to the ink-receptive, non-conductive substrate configured to receive and connect to a signal transmission and/or reception device using a non-contact coupling element.

    Abstract: Generally discussed herein are techniques, software, apparatuses, and systems configured for tuning an antenna. In one or more embodiments, a system can include a monopole or dipole antenna, a hardware processor electrically coupled to the monopole or dipole antenna, an amplitude or power detector electrically coupled between the monopole or dipole antenna and the processor to receive signals reflected from the monopole or dipole antenna and determine an amplitude or power of the reflected signals, and a first impedance matching network electrically connected between a feed point of the monopole or dipole antenna and the detector, the first impedance matching network including a variable capacitor, the variable capacitor having a variable capacitance that is set by the hardware processor based on the amplitude or power of the reflected determined by the amplitude or power detector.
