Keep reading to learn more about the different types of antenna connectors and their purposes, and find the right one for you!

What Are Antenna Connectors? 

Antenna connectors are devices that allow radio frequency signal connection between an external antenna and radio equipment. They provide good electrical contact between the radio transmitter and the antenna. These connectors come in various shapes and sizes, suited for both active and passive antenna systems.

Types of Antennas Connectors

Each type of connector has a design compatible with a particular type of radio equipment. Some connectors are for low-frequency signals, while others are for high-frequency signals. When selecting the right antenna connector, you should consider the frequency range, power level, and impedance of your radio equipment.

1. SMA connector

The SubMiniature version A (SMA) connector is used in applications that need high performance, such as wireless communication systems and WiFi routers. The connector was developed in the 1960s and has become one of the most popular RF connectors used today.

The SMA connector has a male and female version. The male version consists of a threaded body with a center pin that mates with the female connector, which has a threaded body and a center hole. The mating of the two connectors provides excellent electrical performance and shielding, making it ideal for RF applications. The threaded body ensures a secure connection and prevents unwanted disconnection. 

2. RP-SMA connector 

The Reverse Polarity (RP) SMA connector is another type of antenna connector. It has reverse gender and reverse threading. It's different from the standard SMA connector, which has a reverse gender but no reverse threading. The application of RP-SMA connectors is wide, such as access points, routers, and wireless devices. They provide superior access for antenna connections with reverse polarity cable assembly. 

These connectors are commonly used in WiFi equipment, particularly for antenna access and connection. They are also used in radio equipment, Bluetooth applications, dipole, Yagi, ground plane, and cellular phone antennas. RP-SMA connectors provide reliable signal transmission with a secure connection and are durable, making them ideal for harsh environmental conditions. The reverse-polarity feature is beneficial in applications where the antenna needs to be installed in a reverse orientation. It also ensures the connectors aren't loose or disconnected, making them a reliable choice for many applications.

3. N-Type connector

The N-type connector is a threaded, weatherproof electrical connection. Its physical specifications include a nickel-plated brass body, silver-plated beryllium copper center contact, and plated nickel-copper alloy rear. It has an operating temperature range from -67°F to 167°F and an operating voltage of up to 11 kV. The electrical specifications of the N-type connector include a maximum power of 300 W, VSWR of 1.3 max, and a frequency range from DC to 11 GHz. It has a nominal impedance of 50 Ohms and a dielectric withstanding voltage of 1,500 VRMS. 

The N-type connector is designed to meet the requirements of MIL-STD-348 and RoHS standards, providing high quality and performance. It is suitable for various applications, including military, broadcast, and telecommunications. Furthermore, it is useful in harsh environments due to its weatherproof construction. This makes it ideal for outdoor applications.

4. MMCX connectors

Micro-Miniature Coaxial (MMCX) connectors are antenna connector types used for RF connections. They are small in size with a low-profile design, thus suitable for limited spaces. They provide quick connect/disconnect capability and are resistant to the environment, providing reliable performance in harsh conditions. MMCX connectors handle frequencies of up to 6 GHz. The connectors can withstand temperatures ranging from -55°C to 155°C and have a power handling of 63 W @ 1 GHz. 

They offer a snap-on design for quick and easy assembly. MMCX connectors are reliable and robust, offering secure connections with high durability even after multiple mating cycles. They are useful in antenna applications, medical devices, and test equipment. They are also ideal for antenna deployments in remote locations due to their quick assembly and secure connections.

5. TNC connector

This connector is commonly used in WiFi and other wireless technologies. It's usually made of stainless steel, brass, or copper and features a threaded coupling nut for a secure connection. The TNC connector is typically 50 Ohms but can also be 75 Ohms. It has an impedance-matched design, which reduces signal reflections and maintains a higher signal-to-noise ratio. The TNC connector is also designed for quick connect/disconnect applications, making it ideal for mobile or temporary installations. 

6. FME connector

FME is a powerful connection technology that allows you to integrate your data from different sources into FME. It enables real-time synchronization of multiple data sources, data replication, data migration, and complex mapping of heterogeneous data. It helps streamline your workflows, uncover business insights, and unlock the power of data with advanced analytics. 

This connector is particularly useful for businesses because it provides a secure and reliable way to connect different parts of information systems. It's used in mobile and cellular applications.

7. RP-TNC connectors

This is a coaxial RF connection type common in WiFi applications. It has an outer sleeve with a threaded nut and an inner ferrule that holds the center pin. This type of connector provides low insertion loss and a secure connection, making it ideal for high-frequency applications. It is also more robust than other coaxial connectors and provides excellent strain relief when connected to an antenna. RP-TNC connectors are often used in WiFi routers and access points. They are also sometimes found on WiFi adapters and other network equipment. 

8. U.FL Connector 

The U.FL Connector is commonly used for connecting WiFi, Bluetooth, and other radio frequency (RF) antenna components. It is a type of miniature coaxial connector. The U.FL Connector is mostly used in PCBs for wireless connection. It is typically used in applications where space is limited, and the connector needs to be close to the antenna. This connector is particularly useful in compact devices like phones or laptops.

Key Uses of Antennas Connectors

Antenna connectors provide secure and reliable connections through reduced signal loss, discontinuity, and impedance mismatch. Their uses range from consumer electronics, communication systems, instrumentation, automotive electronics, and medical devices to aerospace.
