interference level(intercell/intracell) and to find an accurate approximation of the error probability.In the two kinds of receivers, we assessed the impact of smart antenna systems and we considered thecase of
Array Antennas Yagi-Uda antenna, Micro strip patch array, Aperture array, Slotted wave guide array Used for very high gain applications, mostly when needs to control the radiation patternLet us discuss the above-mentioned types of antennas in detail, in the coming chapters.Print...
Antenna Types In this section, we'll introduce the fundamental antenna types. Almost every antenna in the world can be understood as some combination or derivative of the antennas listed on this page. We'll start with the simplest of all antennas, the short dipole antenna (which is basically...
A dipole antenna includes two conductive elements like wires and rods or wires where the feeder at the center & radiating sections of the antenna are on either side. The metal wires’ length is half of the highest wavelength that is λ/2 within free space at the frequency of operation. The...
Phased Array Antenna Phased array antennais developed using multiple antennas on a common PCB or plane. The antennas used here are patch antennas or dipole antennas in a array. This combination of multiple antennas help improve gain as well as directivity. Individually all the antennas of the arr...
An antenna or aerial in radio engineering is a specializedtransducer, designed by an array of conductors which are connected electrically to the transmitter or receiver. The main function of an antenna is to transmit & receive radio waves equally within all horizontal directions Antennas are available...
It also has many of the features you'd find in a typical laptop computer: a WiFi card, a Bluetooth antenna, a dual-core processor, 1 gigabyte (GB) of RAM and a 64-GB solid-state hard drive. It also has a DVD drive and an integrated Web camera. It comes with the Windows Vista ...
telecommunication: phase shift, Tuning, mobile antenna positioning security: camera movement automotive: fuel metering, steering control Why choose MOONS' stepper motors? These step motors from MOONS' include a number of improvements for even greater performance and value: ...
The BS type 1-H (Hybrid) the radio architecture is represented by three main functional blocks, thetransceiver unit array(TRXUA), theradio distribution network(RDN), and theantenna array(AA). The point where a TXU or RXU connects with the RDN is called “Transceiver Array Boundary connector...
The omni-directional capability is ideal where all around coverage is required, and it is one of the reasons why vertical antennas are used for many point to point mobile radio communications. As the vehicle moves, the vertical antenna at the base station will not need to re-orientate their ...
