Product Description
This linear patch antenna is a high-gain microstrip array antenna operating in the 2.3–2.5 GHz frequency band, featuring a low-profile array architecture with overall dimensions of 250 mm × 250 mm × 25 mm. It achieves a gain exceeding 15 dBi, placing it in the moderately high-gain category. The voltage standing wave ratio (VSWR) remains below 1.4 across the entire operating band, demonstrating excellent impedance matching and extremely low transmission loss — significantly outperforming conventional microstrip antennas (which typically exhibit a VSWR of 1.5–2.0). The antenna radiates with energy concentrated in the main beam direction, offering a good front-to-back ratio and directivity, making it suitable for wireless links requiring long-range, high-reliability directional communication.
It adopts horizontal linear polarization design with 40° elevation HPBW and 36° azimuth HPBW. The wide beam angle provides convenient alignment during installation, while up to 90% antenna efficiency ensures efficient signal transmission. Rated power handling reaches 30W with standard 50Ω input impedance, fitted with SMA-Female RF connector for easy cable connection. Weighing only 263g, this lightweight 25mm-thick flat panel structure supports simple mounting in limited space.
Designed for robust outdoor and industrial wireless transmission, this directional wireless patch antenna is widely deployed for UAV telemetry & data link, serving as ground station receiving antenna for long-range drone control and video transmission. It also works perfectly for point-to-point wireless broadband access, WISP backhaul, radar and air traffic control systems, reflector antenna feed, antenna measurement ranges, as well as ground receiving stations for Synthetic Aperture Radar (SAR). Ideal for industrial IoT, remote wireless surveillance and private network communication scenarios.
