  • Design And Physical Realization Of Phased-Array Antennas For MIMO And Beam-Steering Applications

    A phased-array antenna is made up of multiple individual radiating elements and each is fed with an RF signal controlled through phase shifters in such a way that the radio waves from the separate antennas are added together to increase the radiation. The advantages inherent in phased-array systems will enable major new commercial applications, including 5G communications and automotive radar, to exploit the millimeter-wave (mmWave) spectrum. This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems, and examines the new capabilities recently added to electronic design automation (EDA) software such as the NI AWR Design Environment platform.

Aperture Tuning: An Essential Technology In 5G Smartphones

Antenna aperture tuning is essential to enable smartphones to operate efficiently over the ever-increasing range of RF frequency bands and support the transition to 5G. Smartphones need more antennas to support growing RF requirements such as new 5G bands, MIMO, and carrier aggregation (CA), but there is less space for these antennas due to changes in smartphone industrial design. As a result, antennas are becoming smaller, potentially reducing antenna efficiency and bandwidth. Aperture tuning compensates for this problem by allowing antennas to be tuned to operate efficiently on multiple bands and increasing Tx and Rx performance by 3 dB or more.

Integrated Circuits (ICs) And Component EMC Testing

Those who produce IC products for demanding electromagnetic environments must take precautionary measures to test and pass all regulatory EMI and safety requirements. This white paper explores these standards and safety requirements and offers guidance for ensuring that IC products meet them.

Understanding Phase Versus Temperature Behavior

It can be difficult to understand the combination of complex microwave transmission concepts with complex material properties, especially in phase stability versus temperature. This app note will help readers understand this phenomenon, starting with the basics of phase length and phase delay.
