How to choose an Antenna for your application ?
Choosing an antenna can be a difficult task, there are several parameters that need to be taken into consideration. Although It is important to examine several physical, electrical, and economical […]
Smart Antennas and Beam-forming, Understanding with GNU : Part 3
Recap from part-2 of this article Smart antenna systems or sometimes known as adaptive antenna array systems are composed of two major blocks; An adaptive antenna array block and a […]
Smart Antennas and Beamforming, Understanding with GNU : Part 1
Introduction and Definitions: LTE transmission mode 7,8 and 9 defines fixed precoder based beamforming and adaptive precoder based beamforming. Main advantage of beamforming and smart antenna system is that by […]
Antenna Tilt : Mechanical vs Electrical
For RF optimization and Design purposes, engineers/SON algorithms generally recommend tilt changes (not getting into optimization details in this blog), antenna tilt can be changed by two types of mechanisms: […]
What is VSWR and Return Loss
What is VSWR and Return Loss? Wireless communication systems require the proper integration of several components. For example, antennas are connected to the transmitter/receiver, as well as switching and signal […]
VSWR of BTS Antenna port, Why it gets degraded, Good VSWR and Bad VSWR
VSWR is a way to measure transmission line imperfections which is generally caused by the impedance mismatch, in this case between BTS output port and antenna connected to it. Physical […]
