The **PCTMI2458-RPC** is a dual-band, high-performance internal antenna designed primarily for Wi-Fi and Bluetooth applications. It belongs to the **PulseLarsen Antennas** series, specifically engineered for integration into compact electronic devices. --- ### 1. Key Technical Specifications The electrical characteristics are optimized for the 2.4 GHz and 5 GHz ISM (Industrial, Scientific, and Medical) bands. | Parameter | 2.4 GHz Band | 5 GHz Band | | :--- | :--- | :--- | | **Frequency Range** | 2400 - 2485 MHz | 5150 - 5850 MHz | | **Gain (Typical)** | ~2.0 dBi | ~3.0 dBi | | **VSWR** | < 2.0:1 | < 2.0:1 | | **Impedance** | 50 $\Omega$ | 50 $\Omega$ | | **Polarization** | Linear | Linear | | **Radiation Pattern** | Omni-directional | Omni-directional | --- ### 2. Physical Construction & Connectivity The "RPC" suffix usually denotes specific cable and connector configurations used for internal mounting. * **Antenna Type:** PCB (Printed Circuit Board) or FPC (Flexible Printed Circuit) Dipole. This allows the antenna to be thin and slightly flexible. * **Mounting:** Typically utilizes an adhesive backing (3M tape) for easy installation inside plastic device housings. * **Connector Type:** Most variants use a **U.FL (I-PEX)** or **MHF** micro-miniature connector. * **Cable:** Standard 1.13mm or 0.81mm micro-coaxial cable, usually measuring 100mm to 200mm in length. --- ### 3. Common Applications Due to its dual-band nature and small form factor, this part is commonly found in: 1. **IoT Gateways:** Providing connectivity for smart home hubs. 2. **Industrial Handhelds:** Rugged tablets or scanners requiring reliable Wi-Fi. 3. **Set-Top Boxes:** Streaming devices that require internal hidden antennas. 4. **Medical Devices:** Compact monitoring equipment requiring wireless data transmission. --- ### 4. Implementation Example (Design Integration) When integrating this part into a PCB design, the antenna should be placed away from metal shielding to avoid interference. ```markdown Integration Checklist: 1. Distance: Maintain >10mm clearance from metal components. 2. Orientation: Mount vertically for best omni-directional horizontal coverage. 3. Housing: Ensure the plastic enclosure does not contain metallic paint (EMI shielding). ``` ---
