antenna pair

antenna pair

[an′ten·ə ‚per]
(electromagnetism)
Two antennas located on a base line of accurately surveyed length, sometimes arranged so that the array may be rotated around an axis at the center of the base line; used to produce directional patterns and in direction finding.

In [7, 13], a transmit-receive antenna pair selection at the relay is proposed, which dynamically chooses FD or HD transmission mode according to the channel conditions, and the performance outperforms the traditional FD.
This corresponds to the signal from the same transmit/receive antenna pair (x, y) in Set #2: [S.
The signal transmitted through the antenna pair by Tx-Rx antennas separation of 3 m is used as a reference signal.
We investigate the electrical field strength in the vicinity of a single antenna and transmission through a near-field-coupled antenna pair (typical for fire-wire and on-body communication scenarios).
They determine how many different spatial streams of traffic can be sent at one time to improve signal reception (a separate radio and antenna pair is required for each data stream sent and received).
The effectiveness of these algorithms relies on channel reciprocity or symmetry between the uplink and downlink channels for each transmit/receive antenna pair, the phase difference between antenna elements, and signal amplitude.
This provides frequency diversity in addition to the polarization-sense antenna diversity realized by the opposing polarization senses of the CP antenna pair.

To have a quantitative measure of the pulse distortion for face to face orientation between antenna pair, signal fidelity is used as a figure of merit [18-20].
The oppositely polarized antenna pair, when fed by equal-length transmission lines, will create a null that effectively decouples the pair from other antennas that are electrically and physically centered on the decoy axis.
Equipped with its own ground plane and standard connector cables, the antenna pair can be easily mounted inside a notebook or portable device with minimal interaction with the host system.
12, it is seen that the triple band-notch antenna pair exhibits approximately flat magnitude of transfer gain in UWB frequency band, except in the notched bands centered on 3.
