| Summary: | Cognitive radio (CR) exploits the spectrum efficiently and minimizes
the interference between different devices. Meanwhile, multiband
frequency-reconfigurable antennas (FRA) are desirable for CR where
it is beneficial to dynamically reconfigure a single antenna to be
transmitted and/or received on multiple frequency bands. As stated
by the literature review, there is a dearth of work into multiband FRA
that is directly applied in CR applications with substrate-integrated
waveguide (SIW) technology. Frequency-reconfigurable SIW (FRSIW)
is seen as promising for the development of microwave and millimeter
waveband antennas. This study’s key objective is for the technical
operational advances of SIW antennas to be summarized and compared.
The design structure of FRSIW elements using different techniques
is discussed in detail. The findings supported the effectiveness
of FRSIW for managing radio spectrum to work in most efficient way. |
