SELECTION PROCESS
ANTENNA SELECTION CHECKLIST
IS THIS A NEW DEVICE OR AN EXISTING DEVICE TO BE IMPROVED?
Are the mechanics frozen or flexible? Is the antenna location, shape and interconnect solution frozen?
Standard antennas have a quicker time to market compared to custom designs making it easier to integrate
them into projects, while minimizing redesign cycle time and eliminating design fees. A custom design can
be developed to match required electrical and mechanical specifications.
WHAT TYPE OF ANTENNA IS REQUIRED?
• Embedded (on board the device PCB) • Internal (inside device, but not surface mounted)
• External (outside device) • Outdoor (IP67)
WHAT ARE THE MAIN CHALLENGES FOR THIS PROJECT?
AVX offers testing, debugging, designing, and manufacturing to solve challenges including:
• RF specifications • ME specifications • Design layout • Antenna integration • Surrounding interference, etc.
IS A SPECIFIC STANDARD REQUIRED?
• Automotive (PPAP and IATF16949) • High reliability (MIL-PRF, T-Space, SRC9000, etc.)
• IP rating • UL rating • Plenum rating, etc.
WHAT ARE THE ANTENNA SURROUNDINGS?
• Metallic components (heat sink, connectors, battery, big cap) • Additional antennas • Wires • Flexible FPC
• Audio components (speaker, microphone, earpiece) • High speed digital traces • Specific ground layout
• Shield boxes • Material loading close • Human body (hand, head, body worn device) • Potting material
• Nearby power components • 50 Ohms line to antenna
WHAT IS THE DESIRED FREQUENCY RANGE, MAXIMUM VOLUME AND LOCATION?
Are the electrical and mechanical specifications available, and what is the selected antenna module? When a
bigger antenna volume is available, better performances can be expected. The AVX Antenna Design Team will
suggest the most optimized antenna shape, dimensions, and location based on the product to be developed.
WHAT TYPE OF MOUNTING IS REQUIRED?
• RF cable & connector • SMT • Mag mount • Adhesive mount • Screw mount • Off-board • Pogo pin
• C-clips (spring contacts) • One-ended soldered cable
WHAT TYPE OF CONNECTOR IS REQUIRED?
• SMA • RP-SMA • TNC • RP-TNC • U.fl • W.fl • Fakra • MMCX • BNC • N • NMO
WHAT TYPE OF CABLE IS REQUIRED?
• Micro coaxial 0.8mm, 1.13mm, or 1.37mm diameter • RG58 • RG174 • RG316 • LMR200 • LMR400
• LMR195 • LMR240
FOR AN EMBEDDED SOLUTION, IS PCB CLEARANCE POSSIBLE?
Is the PCB layout available to optimize the distance between the radio and the antenna, and the space from
any threatening surroundings?
ARE THE PCB LAYOUTS & 3D GERBER FILES AVAILABLE?
Helps to define a better antenna placement based on the surroundings and the PCB/product structure
