Abstract
A wireless device includes one or more transmit chains configured to upconvert signals from a baseband frequency to a carrier frequency for transmission over a wireless medium, one or more receive chains configured to down-convert signals received over the wireless medium from the carrier frequency to the baseband frequency, a power rail configured to provide a supply voltage to at least the one or more transmit chains and the one or more receive chains, and a first antenna element configured to transmit the upconverted signals over the wireless medium or to receive signals transmitted over the wireless medium. The first antenna element may be formed using a first signal line associated with the transmit chains, a first signal line associated with the receive chains, or the power rail.
Claims24
A wireless device, comprising:
- first and second circuits interconnected by a first signal line;
- a power source coupled to the first and second circuits by a power rail;
- and
- a first antenna element formed in a segment of the first signal line, the power rail, a signal line within the first circuit, or a signal line within the second circuit, wherein the segment is defined between a first radio-frequency (RF) choke and (ii) a second RF choke, and
- wherein the other segments of the first signal line, the other segments of the signal line within the first circuit, and the other segments of the signal line within the second circuit are not associated with the first antenna element.
A wireless device, comprising:
- a baseband processor and a transceiver interconnected by a signal line, the transceiver including a plurality of radio chains configured to output signals for transmission from the wireless device and to input signals received by the wireless device;
- a power source coupled to the baseband processor and the transceiver by a power rail;
- and
- a first antenna element formed within a segment of the signal line interconnected between the baseband processor and the transceiver, wherein the segment of the signal line comprises a serpentine shape and an effective length of the first antenna element is based at least in part on the serpentine shape.
