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. In some instances, 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. In other instances, the first antenna element may be formed using segments of other signal lines or power rail of the wireless device.

Antenna structure including power and signal lines

Shield design

Methods of manufacturing an antenna are presented. The antenna is capable of being mounted on a printed circuit board. In accordance with the method, the design dimension of a unitary piece of material are selected according to an operating wavelength. The unitary piece of material is stamped out from a larger section of material according to the design dimensions to form an antenna. The unitary piece of material includes a circular area and a stem area. The circular area has a center and an outer region. The stem area has a first end and a second end. The first end is joined with the outer region. The unitary piece is bendable at the first end and the outer region.

Systems to provide and methods to design a printed lumped-distributed balun are presented. A lumped-distributed balun includes a single-ended port, a first differential port, a second differential port, a first phase shifter circuit, and a second phase shifter circuit. The first phase shifter circuit includes a first inductor and a first capacitor. The first inductor is coupled to the single-ended port and the first differential port. The first capacitor is coupled to the first differential port and is adapted to be coupled to ground potential. At least one of the first inductor and the first capacitor is implemented as a transmission line structure, such as microstrip. The second phase shifter circuit includes a second inductor and a second capacitor. The second inductor is coupled to the second differential port and is adapted to be coupled to ground potential. The second capacitor is coupled to the single-ended port and the second differential port. At least one of the second inductor and the second capacitor is implemented as a lumped element.

Systems and methods for mounting an antenna on a printed circuit board are presented. In accordance with the method, an opening is formed through a printed circuit board (PCB). The PCB has a bottom side and a transmission feed on a top side. The PCB is configured to receive an antenna through the opening. An antenna is inserted into the opening on the top side of the PCB. The antenna makes electrical contact with the transmission feed. The antenna is secured to the PCB at the bottom side of the PCB.

A printed balun satisfies performance requirements for operation at a desired operational frequency (e.g., &fnof;&equals;5.3 GHz) while minimizing space requirements on a circuit board. Segments of microstrip are connected at right angles that define fingers whose dimensions can be tailored for operation at a desired operational frequency while minimizing the corresponding space required on a circuit board. Minimal separation between the fingers avoids undesirable internal interference. Mounted at the edges of distinct fingers are the necessary ports for operation of the balun including a single-ended port, an isolation port, and two differential ports.
