dual polarised high gain lte antenna

　　Dual-polarization high-gain LTE antenna is a high-performance antenna optimized for 4G LTE network, which is widely used in base stations, indoor distribution systems (DAS), public safety communications and various wireless broadband access scenarios. This type of antenna improves spectrum efficiency and anti-interference ability by supporting both horizontal and vertical polarization modes, thereby enhancing communication quality and coverage. The following is the key information and technical features of dual-polarization high-gain LTE antenna:

　　1. Technical principle

　　Dual polarization: Each antenna unit can transmit and receive horizontal polarization and vertical polarization signals at the same time. This not only increases the number of available channels, but also improves the robustness and reliability of the system.

　　High gain: By optimizing the design parameters of the antenna, such as reflector shape, feeding network, etc., the antenna has a higher gain in a specific direction, thereby expanding the signal coverage and enhancing the ability of long-distance communication.

　　2. Performance characteristics

　　Wideband coverage: Usually covers multiple LTE bands between 700 MHz and 2.6 GHz, suitable for different operators and service providers around the world.

　　Low intermodulation distortion: High-quality materials and precision manufacturing processes ensure that the antenna can maintain good linearity and stability even in high-intensity electromagnetic environments.

　　High isolation: High isolation between horizontal and vertical polarization reduces self-interference, ensuring signal purity and transmission efficiency.

　　Compact and lightweight: Despite its high performance, its design is small and lightweight, easy to install and transport, and suitable for a variety of application scenarios.

　　3. Application areas

　　Base station antenna

　　Macro base station: Provides wide-area coverage to ensure stable mobile communication services in urban, suburban and rural areas.

　　Micro base station/pico base station: Used to fill small areas or indoor environments that cannot be covered by macro base stations, such as commercial centers, airports, railway stations, etc.

　　Indoor distribution system (DAS)

　　Large buildings: Such as office buildings, shopping malls, hotels, etc., achieve comprehensive and uniform Wi-Fi and cellular signal coverage through distributed antenna systems.

　　Transportation hubs: For example, crowded places such as subway stations and bus terminals ensure that passengers can enjoy a smooth communication experience.

　　Public safety communications

　　Emergency response: Support police, fire brigade and other emergency service agencies to quickly deploy temporary communication networks at disaster sites.

　　Critical infrastructure protection: Security monitoring and command and dispatch of important locations such as power facilities and water conservancy hubs.

　　4. Selection Guide

　　Determine the requirements

　　Frequency and supported technologies: Identify the specific LTE frequency bands that need to be supported (such as 700 MHz, 800 MHz, 900 MHz, 1800 MHz, 2100 MHz, 2300 MHz, 2600 MHz, etc.).

　　Installation location and space constraints: Consider the location where the antenna will be installed and the space constraints around it, and select an antenna of appropriate size and shape.

　　Technical requirements

　　Performance indicators: Evaluate the key performance parameters of the antenna, such as gain, bandwidth, standing wave ratio (VSWR), isolation, anti-interference ability, etc.

　　Environmental adaptability: Ensure that the selected antenna can operate reliably in the expected working environment, including temperature changes, humidity and other external factors.

　　Cost-effectiveness

　　Budget considerations: Select the most cost-effective antenna product based on the project budget, while ensuring that the necessary performance or quality standards are not sacrificed.

　　Regulatory Compliance

　　Certification and Standards: Confirm that the selected antenna complies with relevant industry standards and regulatory requirements of the country or region, such as CE, FCC, etc.

　　Supplier Support and Services

　　Technical Support: Choose suppliers with good reputation and technical support capabilities to ensure the reliability of after-sales service.

　　Customized Services: Some suppliers may provide customized solutions to help customers develop the most suitable antenna system according to specific needs.
