What is meant by antenna reciprocity?
According to antenna reciprocity, the ratio of transmitted power from the transmitting antenna to the received power of the receiving antenna will not change even when the modes of the antennas are interchanged.
What is reciprocity in wireless communication?
This is understood from the reciprocity theorem: If, in a radio communication link, the role of the receive and transmit antenna are functionally interchanged, the instantaneous transfer characteristics of the radio channel remain unchanged.
What is channel reciprocity?
Channel reciprocity is an inherit feature of time division duplex (TDD) system, which is widely used to get uplink (UL)/downlink (DL) channel knowledge from DL/UL channel measurements without additional feedback.
Why do we use reciprocity theorem?
This theorem is applied to analyze Ultrasound Generated by High-Intensity Surface Heating of Elastic Bodies. This theorem is applied to determine line-load-generated surface waves on an inhomogeneous transversely isotropic half-space .
What is reciprocal orientation in marketing?
Reciprocal marketing describes a situation in which two businesses promote each other in order to gain a mutual benefit. Reciprocal marketing is equally popular among small, entrepreneurial Web sites and large, well-established ones.
How does a transmitting antenna work?
How a transmitter sends radio waves to a receiver. 1) Electricity flowing into the transmitter antenna makes electrons vibrate up and down it, producing radio waves. 2) The radio waves travel through the air at the speed of light. 3) When the waves arrive at the receiver antenna, they make electrons vibrate inside it.
What is antenna explain and classify transmitting and receiving antenna?
Antenna can be used for both Transmission and Reception of electromagnetic radiation i.e. a Transmitting Antenna with collect electrical signals from a transmission line and converts them into radio waves whereas a Receiving Antenna does the exact opposite i.e. it accepts radio waves from the space and converts them to …

What is reciprocity theorem in simple words?
The reciprocity theorem states that the current at one point in a circuit due to a voltage at a second point is the same as the current at the second point due to the same voltage at the first. The reciprocity theorem is valid for almost all passive networks.
