Library Philosophy and Practice (e-journal)
Nowadays most discussed technology is mm-wave and 5G communication. The requirement of 5G technology is high bandwidth, high data rate, and low latency. To fulfil these requirements for the current growth in mobile communication multiple input multiple output antenna is used. This bibliometric paper throws light on the various methods used to improve mutual coupling between multiple antennas. Various mutual coupling reduction techniques that are used in MIMO antennas like Dielectric resonator antenna, Electromagnetic Bandgap Structure, Neutralization lines, Defected Ground Structures, Metamaterial, etc. are explained. Scopus database is used for this bibliometric review on mm-wave MIMO 5G technology from the …

Ultra wideband (UWB) technology remains a viable choice for very high speed data communication in future applications involving large bandwidth. For boosting the data communication efficiency and to mitigate the multipath fading issue faced by UWB system with existing narrowband systems, Multiple Input Multiple Output (MIMO) antenna system is used along with UWB. Mutual coupling which must be smaller in value plays a vital role in deciding the efficiency of MIMO antenna and hence it becomes as important aspect. The mutual coupling reduction techniques of various UWB MIMO antennas are surveyed in this bibliometric paper. The bibliometric survey aims to …

Full duplex radios have become a topic of increased interest in the wireless communications community. As part of this development, many efforts were directed to passively decrease the self-interference level at the antenna outputs. However, in many proposed solutions transmission and reception occur through different propagation channels. This paper demonstrates and quantifies the negative impact of channel differentiation on pivotal applications of full-duplex radio, such as cognitive radio. Antenna designs used for self-interference suppression in full-duplex radio architectures are analyzed. In order to ensure that transmission and reception occur within the same propagation channel, the use of the envelope correlation …

On Pattern Reconfigurable Antennas Steered By Modulation Scheme, Adam Narbudowicz, Max Ammann, Dirk Heberling
Conference papers
The paper demonstrates how a modulation constellation can be used to steer the radiation pattern of a reconfigurable omnidirectional circularly polarized antenna. The proposed approach offers the benefit of digital beamforming while using a single antenna: the steering can be executed by low frequency electronics and independently for each frequency channel. In the proposed study, the antenna is excited by a signal generated by two I/Q modulators. By appropriately changing the I and Q components, a phase shift is generated which effectively steers the radiation pattern. The results were achieved using cosimulation between CST Microwave Studio and CST Design Studio.
