The invention solves current problems with MIMO antennas by placing radio frequency (RF) absorber between the antenna and ground.
About
Technology Multiple-Input Multiple-Output (MIMO) antenna configurations with the antenna radiation elements disposed on a duriod substrate and separated at less than half the wavelength. A radio frequency (RF) absorber is incorporated with the antenna to limit the interference. The addition of the RF absorber improves isolation to -15 dB compared to the conventional MIMO antenna with an isolation of -7.3 dB. A benefit of the antenna’s improved performance is the smaller footprint required, which allows for miniaturization. Advantages Invention solves current problems with MIMO antennas by placing radio frequency (RF) absorber between the antenna and ground. Additionally, allows the antenna to be miniaturized for further applications. Allows the signal to be isolated only to the intended antenna, thereby reducing interference. RF absorber is composed of novel ferrite material. Sources https://youtu.be/kSLX6DKpHiM
