An electronic device including an antenna according to various embodiments comprises: a printed circuit board disposed in a first area of the electronic device; a battery disposed in a second area of the electronic device; a heat dissipation member including a thermally conductive material disposed on the upper part of the printed circuit board and the battery; a first antenna disposed in the first area on the heat dissipation member; and a second antenna disposed in the second area on the heat dissipation member, wherein the frequency bands and the dielectric constants of the first antenna and the second antenna may be configured differently.

An antenna assembly for a wireless apparatus (such as a wireless microphone apparatus) comprises two inverted-F antennas. The antenna assembly may be formed from a single stamped sheet metal piece to facilitate manufacturing, which may allow the relative orientation of the two antennas to be reliably maintained. Moreover, manufacturing of the wireless apparatus may be simplified since one antenna assembly rather than two separate antennas may be connected to a printed circuit board of the apparatus. The two inverted-F antennas of the antenna assembly may have a common grounding element that joins the two inverted-F antennas and connects the two antennas to a ground plane of a printed circuit board, where the grounding element of the antenna assembly may be shaped to accommodate a corner of the printed circuit board that the antenna assembly is mounted to.

A base station antenna includes a radio frequency (RF) lens positioned to receive electromagnetic radiation from a radiating element, the RF lens including an RF energy focusing material and a first heat dissipation channel that extends through the RF energy focusing material of the RF lens and contains a cooling fluid.

An antenna for receiving wireless power from a transmitter is provided. The antenna includes multiple antenna elements, coupled to an electronic device, configured to receive radio-frequency (RF) power waves from the transmitter, each antenna element being adjacent to at least one other antenna element. Furthermore, the multiple antenna elements are arranged so that an efficiency of reception of the RF power waves by the antenna elements remains above a predetermined threshold efficiency when a human hand is in contact with the electronic device, the predetermined threshold efficiency being at least 50%. Lastly, at least one antenna element is coupled to conversion circuitry, which is configured to (i) convert energy from the received RF power waves into usable power and (ii) provide the usable power to the electronic device for powering or charging of the electronic device.

An embodiment an antenna unit of an antenna array includes a signal coupler, a phase-shifting modulator, and an antenna element. The signal coupler has a first input-output port, a second input-output port, and a coupled port. The phase-shifting modulator is coupled to the coupled port of the signal coupler, and the antenna element is coupled to the phase-shifting modulator via a connection remote from the signal coupler, or via an isolated port of the signal coupler. The phase-shifting modulator is configured for both relatively low signal loss and relatively low power consumption such that the antenna array can have significantly lower C-SWAP metrics than a conventional phased array while retaining the higher performance metrics of a conventional phased array.
