Quectel has expanded its external antenna portfolio with four combo antennas designed to simplify deployment of connected devices across smart cities, fleet management, industrial automation, utilities, public safety and transport applications.

The YEMA206J1AM, YEMA301J1AM, YEMN308L1BM and YENA00L5AH antennas combine cellular, wifi and GNSS technologies in rugged, compact form factors that help engineers accelerate product development while ensuring reliable connectivity in demanding outdoor and industrial environments.

Using IP67-rated enclosures, high inter-antenna isolation, flexible mounting options and support for multiple wireless standards, the antennas provide a versatile option for IoT deployments.

“Customers increasingly need antennas that combine ruggedness, installation flexibility and support for multiple wireless technologies,” said David Wei, product head at Quectel Wireless. “These new antennas simplify design and deployment while delivering reliable connectivity for applications ranging from vehicle telematics and smart utilities to industrial automation and logistics.”

Designed for compact and discreet IoT deployments, the YEMA206J1AM combines 4G and GNSS connectivity in a rugged two-in-one adhesive mount antenna. Suitable for asset tracking, smart city infrastructure, connected utilities and remote monitoring applications, the antenna delivers reliable cellular and positioning performance in a low-profile form factor suitable for space-constrained installations.

The antenna supports 4G operation across the 698-960MHz and 1710-2690MHz bands and GNSS operation from 1559 to 1606MHz. With efficiency up to 69.4% for 4G-FS and up to 45.3% for GNSS-FS, alongside GNSS LNA gain of approximately 16dB, the antenna helps ensure dependable connectivity and positioning accuracy. Its IP67-rated enclosure enables reliable operation in harsh outdoor environments, while support for 3G, 2G, LTE Cat-M and NB-IoT networks provides flexibility for a wide range of IoT deployments. The antenna is RoHS compliant and compatible with Quectel’s RM520x series modules.

For applications requiring enhanced cellular performance, the YEMA301J1AM integrates dual 4G antennas and a GNSS antenna in a compact three-in-one design. Optimised for field operations and fleet management, automotive telematics, smart city infrastructure, utilities, and HD video streaming applications, the antenna offers robust connectivity while maintaining a discreet installation profile.

Supporting 4G operation in the 698-960MHz and 1710-2690MHz bands and GNSS coverage from 1559 to 1606MHz, the YEMA301J1AM features high inter-antenna isolation to reduce self-interference and increase performance in demanding environments. The antenna delivers efficiency up to 73.2% for 4G DIV-FS and up to 45.3% for GNSS-FS, together with GNSS LNA gain of approximately 16dB. Its rugged IP67-rated enclosure enables deployment in difficult outdoor conditions, while RoHS compliance supports environmental and regulatory requirements.

For connected systems that require high-speed cellular, wifi and positioning capabilities in a single compact package, the YEMN308L1BM combines 5G, wifi and GNSS technologies in a rugged three-in-one external antenna. The antenna is suited to demanding outdoor applications including field operations and mobile connectivity, warehouse and logistics operations, vehicle tracking and telematics, mining vehicles and machinery, HD video streaming, and IoT deployments.

Supporting 5G across the 698-960MHz, 1420-2690MHz and 3300-6000MHz frequency bands, wifi in the 2.4GHz, 5GHz and 6GHz bands, and GNSS operation from 1565 to 1606MHz, the antenna enables reliable, high-performance connectivity across multiple wireless technologies. Its compact form factor allows for discreet installation, while the IP67-rated enclosure ensures dependable operation in harsh outdoor environments. The YEMN308L1BM delivers efficiency of up to 57.2% for 5G-FS and up to 54.09% for GNSS, together with GNSS LNA gain of approximately 18dB. The antenna is also RoHS and Reach compliant.

For multi-network industrial and vehicle connectivity, connected vehicles and industrial deployments, the YENA00L5AH delivers a range of wireless technologies within a single rugged antenna platform. Combining 5G, wifii, AM, FM, Tetra, LTE B88 and GNSS connectivity in a ten-in-one design, the antenna is for smart utilities, smart buildings, industrial automation, digital signage, warehouse and logistics operations, and transport and mining vehicles that require multiple communications services from a single installation.

The ultra-wide-band antenna provides coverage from 1 to 7000MHz, supporting current and legacy network technologies including 5G, 4G, 3G, 2G, LTE Cat-M and NB-IoT. Its integrated architecture incorporates dual 5G, dual N77, dual wifi, dual Tetra, single AM and FM, and active GNSS (L1 and L5) antenna elements, while high inter-antenna isolation helps reduce self-interference and maintain performance across multiple simultaneous connections. Built for demanding operating environments, the YENA00L5AH gas an IP67-rated enclosure that is flame retardant and UV resistant and is both RoHS and Reach compliant.

In addition to its antenna portfolio, Quectel (www.quectel.com) provides antenna design support such as simulation, testing and manufacturing for custom antennas to meet application needs. The company has regional R&D centres across the globe so it can provide a rapid response to requirements. The antennas can be supplied with a range of cable lengths and connector options.
