The antenna is a device that helps to send and receive signals to represent data. Germans invented the first antenna in 1888. This antenna was used for wireless communication. As time passed, different kinds of antennas were invented based on aperture, reflector, aperture, log periodic, and wire.
The antenna comes in various shapes, materials, and elements. A Dipole antenna is one of the most popular kinds of antennas used in different devices and tools. It is also called a doublet. In this blog, we will discuss a dipole antenna, its design, types, benefits and disadvantages, and many other things related to a dipole antenna.
Marine antennas are manufactured in various forms and shapes these days. They are widely used in merchant ships, naval ships, and leisure crafts all over the globe. A Shipboard Antenna is a type of marine antenna that is installed on naval platforms and large vessels.
