W3915

W3915 is an advanced, high-gain RF antenna designed for use in mobile satellite communications systems. It can be used for applications requiring a high degree of power efficiency, compact size and excellent pulse fidelity. This type of antenna has been used for more than 10 years in commercial and military applications.The W3915 was developed based on the same principles used in satellite dish antennas. Its antenna elements contain two copper rods arranged in a spiral and embedded in an epoxy dielectric material. The copper elements are then encapsulated in a double circuit board. The double circuit board provides increased efficiency and improved isolation of the antenna from external EM interference.The main components of the W3915 are the dipole-rod, a dielectric material, a backplane, and the antenna board. The dipole-rod is an insulated rod that is placed in the center of the antenna. The dielectric material acts as an insulator between the antenna and the dipole-rod. The backplane serves as a support structure for the antenna elements and also serves as a connection to the antenna board. The antenna board is the interface between the antenna and the signal processing circuitry. The antenna board is a printed wire board mounted on the antenna and has the necessary electrical components to send and receive RF signals.The W3915 antenna provides a gain of 9 dBi in the L-band (150 MHz to 1 GHz) and 8.5 dBi in the S-band (2 GHz to 8 GHz). Its pulse fidelity is also excellent, providing a high noise rejection and low inter-modulation distortion. In addition, the antenna can be operated in a wide range of temperature and humidity conditions from -40 oC to +65 oC and up to 95% relative humidity.The W3915 is mainly used in applications such as mobile TV broadcasting, digital cellular communication, radio/television broadcasting, and satellite communication systems. It is also used in specialty applications such as airport navigation, forest fire detection, and thunderstorm tracking. With its compact size and excellent radiation parameters, the W3915 is also widely used in electronic warfare systems.In conclusion, the W3915 is an advanced, highly efficient, RF antenna designed for use in a variety of applications. It is capable of providing a high degree of power efficiency, compact size and excellent pulse fidelity. Because of its high gain and wide frequency range, it is suitable for many communication systems.
