• Consist of: Element + Keep out +Ground • Small size, low profile • Ideal for devices with very low height requirement • Relatively large PCB ground keep out of 10 mm to 20 mm is required.

• Consist of: Element + Keep out +Ground • Small size, low profile • Ideal for devices with very low height requirement • Relatively large PCB ground keep out of 10 mm to 20 mm is required.

Consist of: Element + Ground • Higher profile of 5 mm to 25 mm • No PCB ground keep out is required • Can save PCB space • On-ground type ideal for single/dual high band antennas

Compact Antenna • Use existing ground plane • Ground plane design + components/routing can have strong RF impact • Automatic and repeatable assembly

• Larger Antenna • Ground plane independent antenna • Ground plane + components having little impact on RF • Manual assembly

• Stand-alone antenna • Little to no dependency on device ground • Preferred option for metal cases • Option where antenna position different from device position • Minimal RF design effort, ready to use

•Stand-alone antenna • Dependency on device ground increases with lower frequencies • Preferred option for metal cases • Higher gain options available • Adapter cable = adding cost • Easy manipulation with minimal RF design effort

Formed metal embedded antennas can offer high efficiency and may be appropriate for smaller devices where there is limited internal space. TE’s standard off-the-shelf offering of low profile, high performance stamped antennas can deliver a low cost and highly repeatable manufacturing solution. Custom designs can also be provided, however, this is typically only suitable for higher volume applications, as tooling is necessary for stamping and forming. Various mounting options are available.

TE can offer a broad range of external and terminal antennas. As external antennas generally do not require additional tuning, they are easy to implement and therefore may reduce the total cost of ownership. External antennas also have the advantage of improved sensitivity due to farther distance from device noise, which can enable excellent coverage and gain for a wide variety of applications and design possibilities. Most of TE’s external antennas are offered as standard off-the-shelf solutions which supports very rapid time to market. Additionally, TE can offer supplementary cable assemblies and mating RF receptacles (see page 15) that seamlessly connect to the terminated interfaces of the external antennas, which can provide great flexibility for design.
