What are the fundamentals and basic principles of antenna arrays?

An antenna array is a radiating system, which consists of individual radiators and elements. Each of this radiator, while functioning has its own induction field. The elements are placed so closely that each one lies in the neighbouring one's induction field.

What is the simplest antenna design?

Half-wave Dipole Antennas

The half-wave dipole is based on the dipole antenna, which is the simplest practical antenna made of two conductive rods or wires. The “half-wave” term refers to the physical size of the antenna being half of a wavelength at the frequency of operation.

What is the basic structure of antenna?

The three basic segments of the typical insect antenna are the scape or scapus (base), the pedicel or pedicellus (stem), and finally the flagellum, which often comprises many units known as flagellomeres. The pedicel (the second segment) contains the Johnston's organ which is a collection of sensory cells.

What is the most efficient antenna design?

PCB Antennas

The Printed Circuit Board (PCB) antenna is perhaps the most cost efficient type of antenna. As the name suggests, a PCB antenna is printed on the circuit board itself. The antenna consists of a copper trace on the circuit board.

Why is the size of an antenna important?

Traditional antennas are built to receive and transmit electromagnetic waves, which travel fast—up to the speed of light. But electromagnetic waves have a relatively long wavelength. That means antennas must maintain a certain size in order to work efficiently with electromagnetic radiation.
