A wireless antenna, often referred to as an “antenna,” is a specialized device designed to receive or transmit radio waves. These radio waves, a type of electromagnetic radiation, enable the transfer of data over the air, eliminating the need for wired connections. Think of an antenna as t...
Antennaplays a crucial role in this communication system, which is used to transmit and receive the data. The classification of the antenna is based on the specifications like frequency, polarization, radiation, etc. The antenna that is operated at microwave frequency is knows as microwave antenna....
MIMOMultiple-Input Multiple-Output (MIMO) is becoming very common and essential technology in mobile communications due to its great advantage of the downlink speed improvement; however the coupling effect between antenna elements in mobile phones deteriorates gain and correlation of MIMO. To solve ...
This page describes about MIMO basics,MIMO types and MIMO test and measurement solution providers. Multiple Input Multiple Output is the full form of MIMO. Let us understand what input and output refers with. Following figure mentions antennas, for this case there are two antennas in Transmit i...
There are many different types of television antenna & knowing which one to choose can be difficult as they all have their own advantages & disadvantages.
Antenna Design (for Wireless Cards) For Wi-Fi network cards, check the number of antennas and overall design. Cards with at least 2×2 MIMO (two transmit and two receive antennas) are recommended for good coverage and speed. Additional antennas, placement at the edges of the card, and exte...

Vertical antennas form a widely used form of radio antenna. Used in a number of specific areas, their properties enable them to provide performance that horizontal or other antennas are unable to provide.There are several different flavours or types of vertical antenna that can be used from LF ...
Cellphones of the past came equipped with rechargeable nickel-based batteries with (Ni-Cd and NiMH). In the past few years, however, most rechargeable batteries used in phones are Lithium-based. They are either Lithium-ion (Li-Ion) and Lithium Polymer (Li-Po). The fundamental difference ...
