Embodiments are directed to a balun structure comprising: a monopole antenna, and a microstrip coupled to the monopole antenna and comprising a ground plane modified to include at least two arms. Embodiments are directed to a balun structure comprising: a monopole antenna, and a microstrip coupled to the monopole antenna using a stepwise tapered microstrip feed.

Monopole antenna with a tapered Balun

An antenna, including a radiating element configured to have a fundamental resonance frequency being regarded as a first harmonic resonance frequency f, and feed points positioned on the configured radiating element at selected multiple locations that correspond to where a multiple of the first harmonic resonance frequency have current maxima, wherein feeds at the feed points cooperate at an operating frequency of the antenna to constructively combine their respective antenna radiation patterns.

Method and system for multiple feed point antennas

Embodiments are directed to a flexible substrate, and an end-fire antenna array mounted on the flexible substrate, wherein the flexible substrate is configured to be oriented so that array gain is oriented in a direction perpendicular to a plane of the flexible substrate. Embodiments are directed to mounting an end-fire antenna array on a flexible substrate, and orienting the flexible substrate so that array gain is oriented in a direction perpendicular to a plane of the flexible substrate.

Flex PCB folded antenna

A user equipment and a wireless radio frequency assistant in a communication system that supports multiple input multiple output. The wireless radio frequency assistant and the user equipment operate together as a single system. The user equipment controls and activates the wireless radio frequency assistant to transform a first frequency of a radio frequency signal transmitted to the system of user equipment and the wireless radio frequency assistant to a second frequency. The wireless radio frequency assistant transmits the second frequency to the user equipment.

Multiple input multiple output user equipment radio frequency assistant system

Embodiments are directed to a transition structure for interfacing an integrated circuit chip and a substrate, comprising: a co-planar waveguide (CPW) structure formed based on ground-signal-ground (GSG) pads on the integrated circuit chip, a grounded co-planar waveguide (CPWG) structure coupled to the GSG pads, and a microstrip coupled to the CPWG structure.

60 GHz integrated circuit to printed circuit board transitions

Embodiments are disclosed of a switchplexer for performing test operations on a radio device. The switchplexer comprises a plurality of test ports corresponding to a plurality of radio device ports and a plurality of switches for routing test signals between the individual test ports. Processing logic is disclosed for controlling actuation of the switches to route test signals between individual test ports. The switchplexer disclosed herein may be incorporated into a mobile test device for self-test operations or may be used in a manufacturing or maintenance facility for testing and calibration operations.

Systems and methods for testing radio-based devices

Methods, devices and systems for sensor-based wireless communication systems using compressive sampling are provided. In one embodiment, the method for sampling signals comprises receiving, over a wireless channel, a user equipment transmission based on an S-sparse combination of a set of vectors; down converting and discretizing the received transmission to create a discretized signal; correlating the discretized signal with a set of sense waveforms to create a set of samples, wherein a total number of samples in the set is equal to a total number of sense waveforms in the set, wherein the set of sense waveforms does not match the set of vectors, and wherein the total number of sense waveforms in the set of sense waveforms is fewer than a total number of vectors in the set of vectors; and transmitting at least one sample of the set of samples to a remote central processor.
