Product Description

Highlighted Core Features
1. Ultra-Thin Low-Profile Microstrip Patch Structure
This underwater patch antenna adopts advanced microstrip flat patch molding process, featuring ultra-thin low-profile and zero-protrusion structural advantages. Compared with traditional rod, spherical and thick underwater antennas, it greatly reduces installation height and space occupation. The streamlined flat outline avoids underwater flow resistance, collision damage and hanging risks, and will not affect the hydrodynamic performance of underwater mobile equipment. The compact integrated structure is specially designed for miniaturized marine devices, perfectly solving the industry pain point of difficult miniaturization and integration of traditional subsea communication antennas.
2. Dual-Band GPS + Wi-Fi Integrated Compatibility
Integrating high-precision GPS positioning and 2.4G/5G dual-band Wi-Fi communication functions in one single microstrip module, this subsea antenna supports synchronous positioning and wireless data transmission. It breaks the limitation of single-function antennas, realizing one-device dual-purpose to replace two sets of independent antenna modules. Built-in dual-channel signal isolation and filtering technology effectively eliminates mutual interference between positioning and network signals, ensuring fast satellite locking for GPS and low-latency stable transmission for Wi-Fi. It fully meets the dual demands of real-time positioning and wireless networking for modern underwater intelligent equipment.
3. Professional PCB Embedded Integration Design
Specially optimized for industrial PCB board assembly and embedded system integration, this microstrip antenna supports direct soldering and board-mounted installation. It matches standard industrial PCB layout specifications, realizing highly integrated internal assembly of equipment without external wiring and redundant accessories. The standardized modular design simplifies equipment structural development, shortens product research and development cycle, and improves overall equipment integration and aesthetics. It is perfectly compatible with compact underwater sealed cabins, miniature detection sensors and embedded marine monitoring terminals.
4. Underwater Low-Attenuation High-Gain Signal Performance
Calibrated for underwater medium transmission characteristics, this microstrip patch antenna adopts high-precision signal amplification and loss compensation circuits. It effectively resists signal attenuation caused by seawater absorption, suspended sediment shielding and shallow water pressure, maintaining high receiving sensitivity and uniform signal coverage underwater. The professional anti-interference algorithm shields marine electromagnetic clutter and environmental signal noise, avoiding positioning drift and network disconnection. It ensures continuous and stable GPS positioning and Wi-Fi data linkage in long-term underwater working scenarios.
5. IP68 Waterproof & Long-Term Stable Operation
Rated with industry-standard IP68 full submersible waterproof grade, this low-profile patch antenna supports 24/7 uninterrupted shallow and medium-depth underwater submersion and all-weather offshore operation. The high-strength microstrip shell undergoes strict anti-UV, anti-salt spray and acid-base anti-corrosion treatment, resisting long-term seawater erosion, tidal scouring and outdoor aging. The fully enclosed integrated sealing structure completely isolates water vapor, sediment and biological fouling. With industrial low-power design, it supports ultra-long standby and unattended continuous operation, reducing maintenance costs of embedded marine systems.

Professional Application Scenarios
This PCB-integrable GPS/Wi-Fi microstrip patch antenna is widely used in miniaturized and embedded underwater marine projects:
Miniature underwater sensors and detection equipment embedded GPS positioning & Wi-Fi networking
Compact ROV/AUV underwater unmanned vehicle miniaturized communication integration
