Engineering Reliable Wireless Starts at the Antenna

For connected devices, antenna selection plays a critical role in determining signal quality, range, and overall system performance. As wireless standards evolve and devices shrink, the importance of choosing the right antenna—based on frequency, form factor, and integration method—has never been more pronounced.

Amphenol RF’s IoT antenna portfolio addresses these needs with a broad selection of options designed to meet specific application requirements, from embedded systems to high-frequency outdoor devices.

Antennas Engineered for Application-Specific Performance

Amphenol RF offers a wide range of IoT antennas that support key wireless technologies, including Wi-Fi®, cellular, GNSS, and RFID. These antennas are designed to operate across varied environments and system constraints:

• Embedded Chip Antennas – Space-efficient and ideal for high-density PCBs

• Flexible Printed Circuit Antennas – Conform to enclosures or tight mechanical designs

• External Antennas – Provide greater gain and improved range when placement flexibility is available

• GNSS Antennas – Designed for satellite tracking and precision navigation

• Near-Field Communication (NFC) Antennas – For secure, low-range interactions

Each type offers distinct advantages in bandwidth, directionality, and environmental performance.

Target Applications for Modern IoT Antennas

Depending on the wireless protocol and deployment environment, certain antenna designs are better suited for specific applications:

• GNSS & Navigation Systems – Optimize satellite reception for mobile and fixed-location tracking

• RFID and NFC Systems – Focus on reliable coupling for short-range identification and access control

• Wi-Fi®, LTE, and 5G – Prioritize throughput, latency, and coverage

• Radar and Sensing – Support focused transmission and reception for object detection and signal measurement

• Consumer Electronics and Industrial IoT – Require miniaturized antennas that maintain performance within tight enclosures

Design flexibility is a major advantage—Amphenol RF antennas are available in multiple shapes, sizes, and mounting styles to fit the electrical and mechanical constraints of today’s embedded designs.

Key Considerations for Engineers

Selecting the right antenna involves more than matching frequency bands. Engineers must also account for:

• PCB layout and ground clearance

• Matching network design

• Enclosure materials and dielectric properties

• Placement relative to other high-speed components

• Environmental durability and mechanical stress tolerance

Amphenol RF supports engineers with robust documentation, simulation models, and a wide range of tested antenna solutions to reduce design iterations and accelerate time-to-market.
