Spotlight On Antennas
FAQ: Does MLCC Capacitance Change With Voltage?

Voltage fluctuation is known to occur in ferroelectric materials like barium titanate, which is used in most X5R and X7R capacitors. However, the amount of loss experienced can widely vary depending on the dielectric material and the type of voltage, DC or AC, used. 

Phased Array Antenna Patterns—Part 1: Linear Array Beam Characteristics And Array Factor

This article is intended to help an engineer working on a subsystem or component used in a phased array to visualize how their effort may impact a phased array antenna pattern.

Understanding Antenna Gain, Beamwidth, And Directivity

Antenna gain affects, or is affected by, bandwidth, directivity, power, and frequency in oft-misunderstood ways that can differ across antenna types.

Antenna Basics

This white paper describes the basic functionality of antennas. Starting with Hertz's Antenna model followed by a short introduction to the fundamentals of wave propagation, the important general characteristics of an antenna and its associated parameters are explained.

Simplifying MIMO Antenna Installations With The FlexMIMO Antenna

This application note takes a closer look at MIMO antenna installations and how they can be simplified with FlexMIMO antennas from Laird Connectivity.

Introduction To ANSYS 5G Antenna Solutions

This white paper addresses the complexity of designing various points in 5G systems and discusses possible solutions to design and simulate antenna systems, antenna-to-antenna coupling, environmental effects on signal propagation, and V2V/V2X communication.

mMIMO Enables 5G; GaN On SiC Enables mMIMO

While MIMO typically uses two or more transmitters and receivers to send and receive more data at once, massive multiple-input multiple-output (mMIMO) extends that concept by significantly increasing the number of antennas on a single array.
