Types of Antenna An antenna is nothing more than a device built to produce a dispersing electric ormagnetic field. Two fundamental types of antennae are thedipoleand theloop: Figure below Dipole and loop antennas. While the dipole looks like nothing more than an open circuit, and the loop a...
Correct antenna placement is critical to the performance of an antenna. An antenna mounted on the roof will function better than the same antenna installed on the hood or trunk of a car. Knowledge of the vehicle may also be an important factor in determining what type of antenna to use. Yo...
An antenna must be tuned (matched) to the same frequency band as the radio system to which it is connected otherwise reception and/or transmission will be impaired. Types of antenna There are 3 types of antennas used with mobile wireless, omnidirectional, dish and panel antennas. + ...

They are used in main equipment such as high power broadcast transmitters, RF amplifiers and large antenna tuners.Glass CapacitorsGlass capacitors are very exclusive ones with many advantages and applications. As all of the above types, here glass is the dielectric substance. Along with glass ...
Putting up a Dipole A dipole may be erected between 2 supports or with one support. A dipole antenna using a single support is known as an “inverted-V” The legs of a dipole may also be bent to form an inverted U. The bend should be at least half way to the end of the wire ...
1、Ceramic antenna Divided into block ceramic antenna and multilayer ceramic antenna Block antennais used to sinter the whole ceramic body at high temperature and then the metal part of the antenna is printed on the surface of the ceramic block; ...
High-gain antennas that emit the most narrow signal beam of any antenna type Greatest gain of any of the types Typically concave, disk-shaped devices (similar to satellite TV antenna) Parabolic dishes Some are grids (grid antennas) – provides good resistance to wind loading ...
