Vhf Communications Antenna PowerPoint PPT Presentations

Antennas are crucial equipment that helps in wireless communications, and navigation. The two most demanding antennas are the helix antenna and the patch antenna. These are used for similar purposes, but they have many differences that make them suitable for different applications.

This is an introduction to Meteorscatter Amateur Radio: what it is; how it works; what one needs to successfully do meteorscatter VHF communications. The presentation links to actual recorded meteorscatter contacts with video/audio YouTube links. Meteorscatter references and source material is included to give licenced amateur radio operators a good start in this unusual radio medium. The presentation will assist shortwave enthusiasts and those generally interested in meteors and radio. – PowerPoint PPT presentation

A Monopole antenna is half the size of a dipole antenna. It was first discovered by a radio expert Guglielmo Marconi in the year 1895. He patented this antenna after one year in 1896. This radio expert was successful in performing various historical experiments in the field of radio communication.

Antenna transducers are those devices used to convert the radio frequency fields into alternating currents and vice versa. It consists of multiple components such as receiving antenna, transmitting antenna and a transducer. The radio frequency field is generated by the transmitting antenna that is transferred to the receiving antenna which converts these RF into AC with the help of a transducer. The growing trend of automation in flight control and increase in defence expenditure and R&D activities to develop ATR, capable of withstanding harsh conditions and providing long-range capabilities at low power consumption are some of the factors that have supported long-term expansion for Antenna, Transducer and Radome Market.
