Fractal Multiband Antennas Based On Polygons

, 2003
A general procedure for the construction of new fractal multiband antennas is presented along with results for the pentagonal design. An increasing frequency ratio is found with an increase in the number of sides of the polygon used to construct the ...

Reconfigurable Antenna Booster System for Multiband Operation in IoT Devices With an SP4T Switch

IEEE Open Journal of Antennas and Propagation
The increase in the IoT (Internet of Things), such as trackers and sensors, puts pressure on device dimensions and performance. This is translated to the antenna system since it has to be both efficient and provide operation across different frequency ...
