Omnidirectional internal antenna for GPS
Omnidirectional internal antenna for GPS. The antenna operates in band 1545.72 MHz. The antenna reaches up to 30 dBi gain when combined with an amplifier. It is suitable for use in cars and other means of transport. Here it is used for navigation and tracking systems, electronic books and other devices. A cable RG 174/U with a length of 3 m is attached to the antenna, which is terminated with SMA (m) connector.
Connector specifications SMA: These are high-frequency connectors with screw connection mechanism. The characteristic impedance of the connector is 50 Ohm and the operating frequency range up to 18 GHz. There are two types of SMA connectors, namely SMA and RP-SMA. Most of the current cellular routers are equipped with SMA connectors for connecting Wi-Fi / 2G / 3G / LTE / GPS antennas terminated by proticates. It is also used as a standard connector in RF measuring technology. They are characterized by high reliability, durability, high mechanical stability and optimal electrical properties. Cable specifications RG174 / U: The cable labeled RG174 / U is a basic variant of a coaxial cable that is compatible with connectors applicable to a cable diameter of 2.8 mm. The characteristic impedance of the cable is 50 Ω. The reduction factor is fixed at 0.66. The operating temperature range is -20 to 80 °C. Technical parameters can be found in the attached datasheet.
It is most often used for creating cable adaptors with connectors such as BNC / FAKRA / FME / MCX / MMCX / N / SMA / SMB / SMP / TNC and others. It is ideal for short and bending stressed connections in measuring and telecommunications technology, for GPS / GSM / WLAN antennas, antenna leads etc.
