And on the subject of tuning, nearby dielectric materials like plastics, glass, or ceramics can throw off the resonant frequency of the antenna if they aren’t taken into account in the antenna matching and tuning process. Account for this in your antenna test and tuning plan. Our collection of webinar recordings covers a wide range of topics presented by technical experts from Laird Connectivity. Learn about all things wireless - From industry insight to deep dive discussions on IoT gateways, Bluetooth modules, and more.

But because an antenna’s transmission capabilities are very sensitive to its surrounding environment, for optimal results, it is best to determine its position before selecting the type.If you hunt around, you can even find “ultra miniature” 0402 SMT antennas that are only 1mm long! So why not just grab a 1mm chip antenna and design your product around it?

Antennas come in different forms and shapes, and what is ultimately selected depends on a consideration Metal plate antennas have high-efficiency, linear gain, and can handle large amounts of power, as well as low bandwidth. They also have high cost and a large footprint, and they may not be ideal in applications requiring smaller form factors. These antennas operate with linearly polarized radiation and can be designed as a monopole, dipole, or inverted-F antenna. There are a number of manufacturers that produce different chip antennas. This gives designers considerable flexibility in selecting the best bandwidth, gain, and form factor for their Bluetooth-enabled devices.

Axial ratio is an important performance indicator for a circularly polarized antenna and represents its purity. Generally, an axial ratio smaller than 3dB indicates good performance.

carry calls from a handset to a base station somewhere in your home. If you use Wi-Fi ( wireless Internet), your computer sends and Bluetooth is a wireless communication technology used for exchanging data across short distances. Bluetooth antennas are designed for use on devices running at 2.4GHz. sizes range from miniature to sub-miniature connections, using RP-SMA, SMA and U.FL connectors. Cable sizes and types vary depending on the connector used. Most Bluetooth antennas are omnidirectional, but small directional antennas of 2.4GHz are options for Bluetooth. Mounting options include through-hole, surface mounts, wall and pole mounts. and US actress Hedy Lamarr (1913–2000), who, with the help of George Antheil, developed a practical system for the US military during World War II. While modern spread-spectrum systems are electronically controlled, Lamarr's, which is illustrated below, was based on the mechanical, punched paper-tape technology originally used in Wireless Applications, U-NII, ISM Applications, IoT Devices, Smart Home Networking, Sensing, Remote Monitoring

The matching network is designed to optimize the antenna impedance to match 50 Ohms. For an acceptable S11/VSWR of the antenna, some antennas will be required to have a matching circuit. This is normally specified in the application guide. The application guide also references many other guides to achieve optimized antenna performance. This is first in a series of posts to help guide your Bluetooth RF design. It explains the four critical RF factors that impact your antenna choice. Integrations that have followed the Best practices for library authors will automatically connect via the adapter with the best signal and failover to an active adapter if one becomes unavailable. Passive Scanning Testing Bluetooth's flexibility by Dan Simmons. BBC News, 26 October 2007. Summarizes the pros and cons of everyday Bluetooth use. Bluetooth Low Energy (BLE) has fewer channels (40) than standard Bluetooth (79), but from your antenna’s perspective there’s no difference – it’s all the same frequency band.
