The **MA66FAA-R** is an ultra-wideband (UWB) internal flexible printed circuit (FPC) antenna manufactured by **Taoglas**. It is designed specifically for high-precision spatial awareness, asset tracking, and secure keyless entry applications. ### 1. Key Technical Specifications The following table summarizes the primary electrical and physical characteristics of the MA66FAA-R: | Parameter | Specification | | :--- | :--- | | **Antenna Type** | Flexible PCB (FPC) | | **Frequency Range** | 6.0 GHz to 9.0 GHz | | **Peak Gain** | 5.5 dBi (at 8.0 GHz) | | **Efficiency** | > 70% | | **Impedance** | 50 $\Omega$ | | **Polarization** | Linear | | **Connector Type** | I-PEX MHF® I (U.FL compatible) | | **Cable Type** | 1.13mm Coaxial | | **Dimensions** | 22 x 15 x 0.2 mm | --- ### 2. Major Electronic Features * **Ultra-Wideband Performance:** It supports UWB Channels 5 through 9, making it compatible with global UWB standards used by Apple (U1 chip), Samsung, and Decawave (Qorvo) modules. * **Omni-directional Radiation Pattern:** Designed to provide stable coverage in all directions, which is critical for "Time of Flight" (ToF) calculations used in distance sensing. * **Form Factor:** The FPC (Flexible Printed Circuit) design allows it to be bent or adhered to curved surfaces inside plastic device housings using its 3M adhesive backing. * **Low Return Loss:** Engineered to maintain a return loss of less than -10dB across its operating bandwidth, ensuring minimal signal reflection and maximum power transfer. --- ### 3. Application Examples The electronic properties of the MA66FAA-R make it suitable for the following integrations: 1. **RTLS (Real-Time Location Systems):** Indoor positioning with centimeter-level accuracy. 2. **Automotive:** Digital car keys and secure "Passive Entry Passive Start" (PEPS) systems. 3. **Consumer Electronics:** Smart home sensors and "Find My" compatible tracking tags. 4. **Industrial IoT:** Monitoring the precise movement of AGVs (Automated Guided Vehicles) in warehouses. --- ### 4. Integration Guidelines When integrating this part into a circuit, developers should consider the following: ```markdown * Ground Plane: Keep the antenna away from metal components to avoid detuning. * Placement: Mount on the inner side of a non-metal (plastic/glass) enclosure. * Cable Routing: Ensure the 1.13mm micro-coaxial cable is not pinched or tightly coiled. ```
