Special Issue Information

Dear Colleagues,

Antennas and antenna arrays play an essential role in the implementation of modern wireless communication systems such as 5G, 6G, and IoT (Internet of Things) networks. In addition to transmitting and receiving electromagnetic signals, antennas can also be used for RF energy harvesting, which is also expected to be an important part of IoT systems. Several physical layer advance communication techniques have been developed based on intelligently utilizing antennas such as multiple-input multiple-output (MIMO), massive MIMO, integrated sensing and communication, reflective intelligent surfaces, metamaterials and rectennas (energy harvesting). Thanks to these advanced antenna techniques, future wireless communication and sensing networks are expected to achieve much higher data rates, high energy efficiency, low power operations, and smaller sizes.

As 5G, 6G, and IoT systems continue to evolve to support more functions and higher data rates with higher energy efficiency, further innovations and advancements in antennas and antenna arrays are required to meet the growing demands of these systems.  Moreover, algorithms and machine learning techniques for antenna design, optimization, signal processing and RF circuit design are also important to support these advancements and innovations.

This Special Issue aims to publish a collection of novel, innovative and cutting-edge recent research articles on antenna design and optimization, related signal processing techniques, applications of machine learning methods in antennas design, RF energy harvesting and RF front-end design studies for 5G, 6G and future IoT systems. Novel research articles and comprehensive review manuscripts on the state-of-the-art antenna techniques are welcomed. The research topics of this Special Issue include, but are not limited to, the following:

  • Antenna design for IoT devices;

The limitations of conventional sensors have made array antennas increasingly crucial for gathering information and communication applications in intelligent transportation and communication systems. Compact cylindrical arrays are particularly favored for their ability to achieve azimuth angle scanning. However, the substantial mutual coupling effect between the elements on curved surfaces and its implication for these arrays remain unclear, which is a key factor to consider when such arrays are used for multibeam applications. This study investigates the effect of mutual coupling in a dual-slant-polarized cylindrical array. The results showed that mutual coupling is predominantly observed among the closely located elements, and it is essential for achieving an ultra-wide bandwidth. The study also analyzes the impact of mutual coupling on the scan impedance and radiation characteristics for multibeam applications and reveals that these arrays exhibit robust multibeam capability, hence having great potential for use in sensing and communication applications.
