Diversity gain antenna
WebFeb 14, 2024 · Using diversity gain, the effect of the diversity scheme on the radiated power can be described. Figure 13 shows the diversity gain of the proposed MIMO antenna which is a flat line in the ideal value for 10 dB for all four elements except the notched band. The DG is computed as a function frequency using relation (3). WebCooperative diversity: Achieves antenna diversity gain by using the cooperation of distributed antennas belonging to each node. Combiner techniques [ edit ] An important element in communication systems applying diversity schemes is the "Combiner", which processes the redundantly received signals.

WebThe conditions for antenna diversity action are investigated. In terms of the fields, a condition is shown to be that the incident field and the far field of the diversity antenna should obey (or nearly obey) an orthogonality relationship. The role of mutual coupling is central, and it is different from that in a conventional array antenna. In terms of antenna … Web7.2.1 Beam-Forming, Precoding, and Diversity.
