Antenna frequency
An antenna capable of transmitting or receiving electromagnetic (EM) waves. Examples of these electromagnetic waves include light from the sun, and the waves received by your cell phone. Your eyes are receiving antennas that detect electromagnetic waves at a specific fre...Read more -
The importance of antennas in the military field
In the military field, antennas are a very important technology. The purpose of an antenna is to receive and transmit radio frequency signals to enable wireless communication with other devices. In defense and military aspects, antennas play a vital role as they are used...Read more -
Antenna bandwidth
Bandwidth is another fundamental antenna parameter. Bandwidth describes the range of frequencies that the antenna can correctly radiate or receive energy. Typically, the required bandwidth is one of the parameters used to select the antenna type. For example, there are m...Read more -
Antenna efficiency and antenna gain
The efficiency of an antenna is related to the power supplied to the antenna and the power radiated by the antenna. A highly efficient antenna will radiate most of the energy delivered to the antenna. An inefficient antenna absorbs most of the power lost within the anten...Read more -
What Is a Planar Antenna? Structure, Types and Applications
A planar antenna is a low-profile antenna whose radiating structure is arranged on or parallel to a flat surface. Depending on the design, the radiating elements may be printed metal patches, slots, spiral conductors, waveguide apertures, or multiple elements combined as...Read more -
Antenna Directivity: Formula, Gain and Measurement
What Is Antenna Directivity? Quick answer: Antenna directivity describes how strongly an antenna concentrates radiated power in a particular direction compared with an ideal isotropic radiator. An isotropic radiator has a directivity of 1, or 0 dBi. Higher directivity pr...Read more -
Standard Gain Horn Antenna: Understand Its Working Principle and Application Areas
The standard gain horn antenna is a commonly used directional antenna, consisting of a transmitting element and a receiving element. Its design goal is to increase the gain of the antenna, that is, to concentrate radio frequency energy in a specific direction. Generally ...Read more -
Biconical Antenna: Working Principle, Design and Applications
A biconical antenna is a broadband antenna formed by two conductive cones positioned tip to tip and fed at their apexes. Its gradually changing geometry provides a wider operating bandwidth than a conventional thin-wire dipole, making it useful for wideband measurement, ...Read more -
Introduction to log-periodic antennas and their application fields
The log-periodic antenna is the preferred antenna form for low-frequency ultra-wideband directional antennas. It has the characteristics of medium gain, operating frequency bandwidth, and good performance consistency within the operating frequency band. Suitable for carr...Read more
