## WPANTDP088-R1A: Electronic and Technical Specifications The **WPANTDP088-R1A** is a specialized, high-performance **dual-band embedded antenna** manufactured by World Products Inc. It is primarily designed for wireless communication applications where space is limited but high efficiency is required. --- ### 1. General Overview This component is a **PCB (Printed Circuit Board) antenna**. Unlike external whip antennas, this is designed to be integrated directly inside a device’s housing, usually connected via a micro-coaxial cable. ### 2. Technical Specifications The electrical characteristics define how the antenna interacts with radio frequencies. | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 2.4 - 2.5 GHz / 4.9 - 5.875 GHz | | **Bands Supported** | Wi-Fi 2.4GHz, Wi-Fi 5GHz, ISM, UNII | | **Peak Gain (2.4 GHz)** | ~2.0 dBi | | **Peak Gain (5.0 GHz)** | ~3.0 dBi | | **Impedance** | 50 Ohms | | **VSWR** | < 2.0:1 | | **Polarization** | Linear (Omni-directional) | --- ### 3. Key Electronic Components & Materials The "Electronic parts" of this assembly consist of three main segments: #### A. The Radiating Element (PCB) * **Material:** Typically constructed on a FR4 or high-frequency laminate substrate. * **Design:** It uses a specialized copper trace pattern (often a meandered inverted-F or dipole variation) to resonate at two distinct frequency bands. * **Coating:** A solder mask (usually green or black) protects the copper traces from oxidation. #### B. The Feedline (Coaxial Cable) * **Type:** 1.13mm or 1.32mm micro-coaxial cable. * **Function:** Delivers the RF signal from the Wi-Fi module to the antenna element with minimal signal loss. * **Shielding:** Braided copper shielding prevents EMI (Electromagnetic Interference). #### C. The Connector * **Standard:** **IPEX / MHF / U.FL** (compatible). * **Function:** Provides a snap-on connection to the wireless card (e.g., Mini PCIe or M.2 Wi-Fi cards). --- ### 4. Implementation Details * **Mounting:** It features an adhesive backing (3M tape) for easy installation on the inner plastic casing of a device. * **Ground Plane Dependency:** As an embedded PCB antenna, its performance can be affected by nearby metal objects. It is designed to be "ground plane independent," meaning it does not strictly require a large metal sheet to function correctly, though clearance is still recommended. --- ### 5. Common Applications * **IoT Gateways:** Smart home hubs. * **Industrial Routers:** Wireless data transmission in factories. * **Set-top Boxes:** For streaming video over dual-band Wi-Fi. * **Embedded Systems:** Custom Raspberry Pi or Arduino projects requiring long-range Wi-Fi.
