Study of Substrate-Materials Impact on Compact Antenna Performance
(Institute of Electrical and Electronics Engineers Inc., 2022) Mahmood, S.N.; Saeidi, T.; Ismael, A.R.; Alani, S.
Improving bandwidth and reducing size are significant design aspects for practical compact antenna applications. To reach wideband and decrease the scale of microstrip antennas, numerous strategies were brought into practical action. This article demonstrates a survey of various miniaturization strategies. It analyzes the effectiveness of the compact and miniaturized multi-use antennas in terms of their size, forms of substrate material, conductivity, loss tangent, and thickness that can influence the bandwidth, gain, radiation efficiency, Specific absorption rate (SAR) value antenna type, feeding techniques, and further significant parameters. Noteworthy, the most popular technique is to use a high dielectric constant for its substratum content to reduce the size of a printed antenna. Thus, the directed wavelength under the patch and the resonant patch size can be decreased correspondingly. © 2022 IEEE.
