915MHz 4dBi Internal PCB Antenna with 1.13mm Cable (L-10cm) + UFL Connector

Listing ID #7508567

The description you’ve provided refers to a specific antenna configuration. Here’s a detailed breakdown:

1. 915MHz: This is the operating frequency of the antenna. The 915 MHz frequency is commonly used in the ISM (Industrial, Scientific, and Medical) band for applications such as RFID, IoT devices, and some wireless communication systems.

2. 4dBi: This indicates the gain of the antenna. A gain of 4dBi means the antenna has moderate directivity and efficiency, providing a balanced trade-off between coverage area and signal strength.

3. Internal PCB Antenna: This type of antenna is designed to be mounted directly onto a printed circuit board (PCB). Internal PCB antennas are used when space is limited and an external antenna is not feasible. They offer a compact solution that integrates well within the device.

4. 1.13mm Cable (L-10cm):

   • 1.13mm Cable: Refers to the coaxial cable with a diameter of 1.13 mm. This cable is thin and flexible, suitable for applications where space constraints exist and a compact connection is needed.
   • L-10cm: The length of the cable is 10 centimeters, providing enough length to connect the antenna to the PCB while keeping the overall design compact.

5. UFL Connector: UFL (also known as UMCC) is a very small, micro miniature connector used for connecting antennas to circuit boards. It is ideal for situations where space is tight and a compact, reliable connection is needed.

• 915MHz: Designed for RF communication in the 915 MHz frequency band.
• 4dBi Gain: Provides a moderate level of directivity and signal strength.
• Internal PCB Antenna: Space-saving design mounted directly on the PCB.
• 1.13mm Cable (L-10cm): Thin, flexible coaxial cable with a length of 10 cm for compact internal connections.
• UFL Connector: Compact connector for secure attachment to the PCB.

This setup is suitable for devices that operate at 915 MHz and require an internal antenna solution. It is commonly used in compact electronics, including IoT devices, RFID systems, and other wireless communication systems where internal space is limited and a small, efficient antenna is needed. The 10 cm cable length provides flexibility in positioning the antenna, while the UFL connector ensures a secure and compact connection.
