The **ANT-2.4-CW-RCT** is a high-performance 2.4 GHz dipole antenna designed by Linx Technologies (now part of TE Connectivity). It is commonly used for Wi-Fi, Bluetooth, ZigBee, and other ISM band applications. ### 1. Technical Specifications The following table summarizes the key electronic characteristics of the antenna: | Parameter | Specification | | :--- | :--- | | **Frequency Range** | 2.4 GHz to 2.5 GHz | | **Peak Gain** | 2.2 dBi | | **VSWR** | ≤ 1.9 (at center frequency) | | **Impedance** | 50 $\Omega$ | | **Wavelength** | 1/2-wave | | **Polarization** | Linear | | **Radiation Pattern** | Omnidirectional | | **Connector Type** | RP-SMA (Male) or SMA (Male) | --- ### 2. Design and Construction The antenna is engineered for durability and flexibility in various electronic deployments. * **Articulating Base:** The "RCT" series features a knuckle swivel design that allows the antenna to tilt 90 degrees and rotate 360 degrees. This is crucial for optimizing signal orientation. * **Dipole Internal Structure:** Unlike monopole antennas, this is a **center-fed 1/2-wave dipole**. This means it does not require a ground plane on the host PCB to operate efficiently, making it ideal for plastic enclosures. * **Internal Element:** It typically utilizes a brass or copper radiating element protected by a ruggedized UV-stabilized ABS plastic radome. --- ### 3. Connection and Implementation When integrating this part into a circuit, developers should consider the following: #### Connector Polarity The ANT-2.4-CW-RCT is most commonly found with an **RP-SMA** (Reverse Polarity SMA) connector. This is the industry standard for Wi-Fi equipment to comply with FCC Part 15 regulations. #### Signal Integrity To connect this to a PCB, a high-quality coaxial cable or a PCB-mount connector is required. ```cpp // Example: Hardware considerations for RF output #define ANTENNA_IMPEDANCE 50 // Ohms #define MAX_VSWR 1.9 void checkRFDesign() { // Ensure the PCB trace (Microstrip) is calculated // for 50 Ohm matching to avoid signal reflection. if (trace_impedance != ANTENNA_IMPEDANCE) { apply_matching_network(); // L-C Pi network } } ``` --- ### 4. Typical Applications * **Wi-Fi Routers:** Enhancing range for 802.11b/g/n devices. * **Bluetooth Gateways:** Increasing the connection stability for IoT hubs. * **Industrial Monitoring:** Used in ZigBee or Thread mesh networks in factory environments. * **SDR (Software Defined Radio):** General-purpose 2.4 GHz band monitoring.
