Discover the essential role of Ununs in RF antenna systems in our article. Explore their applications, understand the difference between BALUN and UNUN, and get a clear definition of what an Unun is in the context of RF antennas. Whether you're a radio e
MIMO (multiple input, multiple output) is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver). The antennas at each end of the communications circuit are combined to minimize errors, optimize data speed...

Editorial Team - everything RFJan 22, 2021 The Axial Ratio (AR) of an antenna is defined as the ratio between the major and minor axis of a circularly polarized antenna pattern. If an antenna has perfect circular polarization then this ratio would be 1 (0 dB). However, if the antenna ...
Let us first recallwhat actuallyMIMOis? MIMOis an acronym forMultipleInput,MultipleOutputs.It is a radio antenna technology that uses multiple antennas at the transmitter and receiver to improve the radio link'squality,throughput, andcapacity. MIMO employs spatial diversity and spatial multiplexing tec...
Antenna diameter – Maximizing the coil diameter improves efficiency. 25-70mm typical for small devices. Geometry – Square or circular antenna geometries are commonly used. 2. Impedance Matching The antenna impedance is matched to the NFC chip’s tuned input impedance of 13-15pF via an impedance...
The radiofrequency modulated signal is amplified to adequate strength by the RF PA once it is generated by the modulator and then sent by the antenna through the matching network. 2. Principle Take a close look at the green label. First, the RF signal enters from the left, goes through a...
Since massive MIMO uses many more antennas than the number of UEs inthe cell, the beam is muchnarrower, enabling the base station to deliver RF energy to the UE more precisely and efficiently. The antenna's phase and gain are controlledindividually, with the channel information remaining with ...
(MoM) to compute port properties such as impedance, surface properties such as current and charge distribution, and field properties such as the far field radiation pattern. Antenna Toolbox provides impedance analysis that can be used to design matching networks withRF Toolbox™. It also ...
