Abstract

Tightly coupled array (TCA) antenna has become a hot topic of research recently, due to its

potential of enabling one single antenna array to operate over an extremely wide frequency range. Such an

array antenna is promising for applications in numerous wideband/multi-band and multi-function wireless

systems such as wideband high-resolution radars, 5G mobile communications, satellite communications,

global navigation satellite systems, sensors, wireless power transmission, internet of things and so on. Many

papers on this topic have been published by researchers internationally. This paper provides a detailed

review of the recent development on TCA that utilizes the capacitive coupling. The basic principles and the

historical evolution of the TCAs are introduced firstly. Then, recent development in the analysis and design

of TCAs, such as equivalent circuit analysis, bandwidth limitation analysis, array elements, feed structures,

substrates/superstrates loading, etc., are explained and discussed. The performances of the state-of-the-art

TCAs are presented and a comparison amongst some TCAs reported recently is summarized and discussed.

To illustrate the practical designs of TCA, one case study is provided, and the detailed design procedures of

the TCA are explained so as to demonstrate the TCA design methodology. Simulated results including the

VSWR at different angles of scanning, patterns and antenna gain are shown and discussed. A conclusion

and future work are given in the end.
