RFAntennas Applications and Working Principles

RFAntennas are important components for the working mechanism of communication devices. Alpha 8 / 1M / FMEF / S / S / 11 antennas are the ones which are used for transmitting and receiving radio signals. It is comprised of receiving horn antenna, helical antenna, directional yagi antenna, omni directional dipole antenna, circularly polarized horn antenna, patch antenna and fractal antenna. These antennas radiate energy in horizontal pattern and supports applications such as satellite communication, radio navigation, cellular networks, television broadcasting, radar systems and avionic wireless systems.

Application Field:

Alpha 8 / 1M / FMEF / S / S / 11 antennas are used in many applications depending upon the operational frequency and requirements of network. It is ideal for satellite communication, radio navigation, cellular networks, television broadcasting, radar systems and avionic wireless systems. These antennas provide excellent interference rejection and transmit high frequencies signals efficiently. Furthermore, these antennas are widely used in satellite communications, GPS systems, cellular base stations, avionic applications and radio broadcasting.

Operating Principles:

Alpha 8 / 1M / FMEF / S / S / 11 antennas primarily works on the principle of electromagnetic wave radiation. This antenna will generate a pattern radiation with an omnidirectional horizontal linear polarization. The primary working element of this antenna is the EMCoilwhose working is based on EM fields. The EM Coil creates an electromagnetic field which radiates the outward in all directions. This radiated energy is collected by the receivers according to their orientation and transmit a signal accordingly.

The dipoles also create a sinusoidal EM field depending upon the frequency range and the signal is received by the receivers. The gain of the antenna is directly proportional to the operating frequency and the number of elements used in the antenna. Generally, higher frequency requires more number of elements for transmission and reception of the signal.
