Introduction To Broadband Antennas

- Dec 14 2017 - An antenna is a device that radiates a high frequency electromagnetic energy (information) through a variety of metal conductors in a variety of shapes. It can also receive the electromagnetic energy (information) of the space. That is to say, there is no fundamental difference between the transmitting antenna and the receiving antenna.
The antenna has a magnetic field antenna and an electric field antenna. The measuring frequency of the magnetic field antenna is 25HZ-30MHZ, while the frequency range of the electric field antenna is in the range of 10KHZ-40GHZ.  According to the different uses, the antenna is divided into two types of active and passive. Wide-band antennas are used in EMC measurement.
Wideband Antennas refer to antennas with wide bandwidth, such as conical antennas, V cone antennas, TEM horn antennas, log periodic antennas, helical antennas, corrugated horn antennas, microstrip antennas, new antennas, and electrically small antennas.
