Learn how to measure and compare the performance of antennas using gain, a parameter that combines directivity and efficiency. Find out the difference between dBi and dBd, and see how to calculate and plot antenna patterns.
Learn what antenna gain means and how it is measured in dBi and dB units. See examples of how antenna gain affects the energy distribution and compare different antennas.
dBi Values Explained: dBi = dB(isotropic): The forward gain of an antenna, measured in decibels (dBi), The dBi value reflects the antenna's directional / beamwidth characteristics, i.e., directional as opposed to omnidirectional: Generally, the higher the gain (dBi), the narrower the beamwidth - the more directional the antenna. The dBi value also reflects the antenna's electrical efficiency ...
Learn how to measure and compare the power gain of signal boosters and antennas using dB and dBi. Find out how dBi relates to isotropic antenna pattern and how it affects your cell phone signal strength.
Learn how to measure and compare antenna performance using dB, dBm, dBi, and dBd units. These units express the power, gain, and loss of RF signals and antennas in wireless communications and RF engineering.
Learn how to measure antenna gain using dBi and dB units, and how to choose the right antenna for your radio communication needs. Find out the pros and cons of high, low and mid-gain antennas for long-range, short-range, indoor and mobile applications.
dBi is the unit of antenna gain compared to an isotropic antenna. Learn the difference between dBi and dB, and how to calculate antenna gain in decibels.
dB dBm dBi; dB stands for Decibels. dBm stands for Decibel Milliwatts. dBi stands for Decibel Relative to Isotropic Gain.: It is the measure of loudness.: It is a unit used to express decibels in milliwatts and is often used to measure the strength of the signal in wires and cables.
In this article a compact frequency reconfigurable antenna is presented for wireless communication applications of industrial, scientific and medical band (ISM).
In this paper, the design and development of dual-band and triple-band fractal microstrip patch antennas with enhanced gain are presented. The structure is based on the Sierpinski carpet fractal, where the multiband functionality is achieved by applying the fractal iteration technique.
