Optical Antenna Gain 2: Receiving Antennas

Applied Optics, 1974
Expressions are derived for the gain of a centrally obscured, circular optical antenna when used as the collecting and focusing optics in a laser receiver which include losses due to (1) blockage of the incoming light by the central obscuration, (2) the spillover of energy at the detector, and (3) the effect of local oscillator distribution in the case

An overview of terahertz antennas

China Communications, 2020
The terahertz (THz) antennas, which have features of small size, wide frequency bandwidth and high data rate, are important devices for transmitting and receiving THz electromagnetic waves in the emerging THz systems. However, most of THz antennas suffer

Bandwidth and SNR of Small Receiving Antennas: To Match or Not to Match

IEEE Transactions on Antennas and Propagation, 2023
In this article, the merits of impedance matching a small antenna to the receiver’s impedance are investigated. The goal is to demonstrate that a small antenna with low radiation resistance and high input reactance, when directly connected to a high ...

Deep Learning-Based Cooperative CSI Feedback via Multiple Receiving Antennas in Massive MIMO

ICC 2022 - IEEE International Conference on Communications, 2022
Deep learning (DL)-based channel state information (CSI) feedback can provide high downlink CSI reconstruction accuracy for massive multiple-input multiple-output (MIMO) systems.

Conformal Near-Field Focus Radiation From Phased Array of Antennas to Enhance Power Transfer Between Transmitting and Receiving Antennas

IEEE Transactions on Antennas and Propagation, 2020
In this article, the concept of conformal near-field focus (CNFF) radiation from a phased array of antennas is theoretically presented. The motivation intends to enhance the electromagnetic (EM) power reception by receiving antennas (RXAs) of relatively ...

Effect of Receiving Antennas Radiation Pattern on an SFN Network Coverage

International Symposium on Computers and Communications, 2019
This article presents the results of a series of simulations that aim to analyze the impact of using different receiving antennas in the coverage area of a Single Frequency Network (SFN) under the Advanced Television Systems Committee (ATSC) standard ...
