The **ANT-2.4-WRT-MON-RPS** is a high-performance, external panel-mount antenna designed primarily for 2.4 GHz ISM band applications (Wi-Fi, Bluetooth, ZigBee). It is manufactured by Linx Technologies (now part of TE Connectivity). ### 1. Key Technical Specifications The following table highlights the core electronic and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Frequency Range** | 2.4 GHz to 2.5 GHz | | **Center Frequency** | 2.45 GHz | | **VSWR** | ≤ 1.9:1 | | **Peak Gain** | 0.7 dBi | | **Impedance** | 50 $\Omega$ | | **Polarization** | Linear | | **Connector Type** | RP-SMA (Reverse Polarity SMA) | | **Cable Type** | RG-174 Coaxial | | **Mounting Type** | Permanent Panel Mount (Screw-mount) | --- ### 2. Electronic Component Analysis #### A. Radiation Pattern and Gain Unlike high-gain directional antennas, the WRT series is designed to be **omnidirectional**. While the peak gain is relatively low (0.7 dBi), this is intentional to provide a broad, consistent signal coverage around the device rather than a long-distance narrow beam. #### B. The "RP-SMA" Connector The **RPS** suffix indicates a **Reverse Polarity SMA** connector. - In a standard SMA, the plug has a center pin. - In an **RP-SMA plug**, the center contact is a **socket (female)**, even though the connector body has internal threads. This is a common regulatory requirement for Wi-Fi equipment to prevent users from attaching unauthorized high-gain antennas. #### C. Coaxial Feed The part utilizes **RG-174** cabling. This is a thin, flexible coaxial cable that provides a balance between ease of routing and signal attenuation. Because 2.4 GHz signals attenuate quickly over distance, these antennas usually feature short cable leads (often 8.5 inches or 216mm) to minimize power loss before the signal reaches the radiator. #### D. Environmental Protection The "MON" series is often characterized by its low-profile "monopole" or "dome" design. It is electronically grounded via its mounting nut, and the outer housing (radome) is typically UV-stabilized impact-resistant plastic, making it suitable for industrial or outdoor enclosures. --- ### 3. Connection Interface Code When integrating this antenna into a system, the RF output from your PCB (e.g., an ESP32 or NRF52 module) must be matched to 50 ohms. If you were defining this in a bill of materials or a simulation environment, it would look like this: ```yaml component: part_number: "ANT-2.4-WRT-MON-RPS" manufacturer: "Linx Technologies / TE Connectivity" category: "RF Antenna" interface: "RP-SMA Male" impedance: 50_ohm mounting_hole_diameter: "0.25 in (6.35 mm)" ```
