01.07.21 -- Guide To Antenna Selection | Antenna Aperture Tuning

Selecting an antenna for testing can sometimes be straightforward but often requires some specific consideration. This application note offers several simple guidelines for choosing the best antenna for your application.

StackiCap surface-mount MLCCs are designed to provide high capacitance values in compact packages and offer the greatest volumetric efficiency and capacitance per unit mass of any high-voltage X7R ceramic capacitors available.

Antenna efficiency plays a critical role in overall smartphone RF performance. Aperture tuning is one technique available to mobile designers to optimize the antenna, but implementing it requires in-depth knowledge.

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.

Designers of LoRa-based end devices face several challenges in getting a product to market, where hardware, software, and cloud connectivity must all seamlessly integrate and operate. This white paper discusses how to make LoRa connectivity smarter with low-power front-end modules.

Digitization at the antenna has been the ultimate objective for implementing a true software radio transceiver. However, the obstacles of achieving high dynamic range and handling a large instantaneous bandwidth have prevented users from having a deployable solution. 

Waveguide horn antennas represent technology that is old but still invaluable, especially for sending and receiving signals well into the millimeter-wave frequency range.

The third article in a three-part series on phased array antenna patterns discusses antenna sidelobes and the effect of tapering across an array. It provides a method to reduce antenna sidelobes at some expense to the antenna gain and main lobe beamwidth.
