Abstract: An RF structure includes a PA, a PA ground switch coupled between the PA output and ground, a LNA, and a LNA ground switch coupled between the LNA input and ground. The RF structure includes a plurality of directional antenna structures, each including an antenna, a transmit quarter wavelength circuit coupled between the PA output and the antenna, a receive quarter wavelength circuit coupled between the antenna and the LNA input, and an antenna switch coupled between the antenna and ground. Switch control circuitry controls the PA ground switch, the LNA ground switch, and the plurality of antenna switches during transmit and receive operations to control the flow of RF receive signals from the antennas to the LNA and the flow of RF transmit signals from the PA to the antennas. The transmit and receive quarter wavelength circuits may be traces or be constructed of lumped circuit elements.

Abstract: A system and apparatus is provided to reduce signal routing, area and signal loss in double-pole, double-throw (DPDT) switch implementations in wireless and millimeter-wave front ends. A staggered arrangement of receivers, transmitters and antenna ports connecting with DPDT switches reduce signal cross-over and allow for compact, low-loss multi-antenna configurations.

Abstract: An antenna array structure includes a plurality of antennas, wherein a first antenna has a first geometric shape, provides a first radiation pattern, and has a first frequency bandwidth. A second antenna has a second geometric shape to provide a second radiation pattern and has a second frequency bandwidth. The first and second frequency bandwidths at least partially overlap to include channels of interest. An antenna processing circuit sends one or more transmit signals to one or more of the antennas for transmission via one or more of the channels of interest and receives one or more receive signals from the one or more of the antennas or from another one or more of the antennas via the one or more of the channels of interest or from another one or more of the channels of interest.

Abstract: An antenna assembly includes a substrate, a plurality of spiral dipole antenna sections, and a phase array feeder. The substrate has a three-dimensional shaped region. Each of the spiral dipole antenna sections is supported by a corresponding section of the three-dimensional shaped region and conforms to the corresponding section of the three-dimensional shaped region such that, collectively, the plurality of spiral dipole antenna sections has an overall shape approximating a three-dimensional shape. The spiral dipole antenna sections are coupled together in accordance with a coupling configuration for beamforming and/or power combining. The phase array feeder inputs, or outputs, a phase offset representations of a radio frequency (RF) signal from, or to, the spiral dipole antenna sections and converts between the phase offset representations of the RF signal and the RF signal.
