Dual-band Frequency Reconfigurable Antennas

21 March 2013


Cristina Borda

Reconfigurable antennas are becoming more widely used due to the increasing number of wireless communications and new functionalities of these systems. Moreover, multiple antennas supporting different wireless bands are not a suitable solution, because of the higher demand of compact size, efficiency, low power consumption and low cost. The aim of this project is to explore new and different reconfigurable techniques for multiple wireless applications at different frequency bands and having stable radiation patterns in all working frequencies. The novel reconfigurable antenna has to be able to operate from multiple tens of MHz to a few GHz, offering stable radiation patterns in all operating frequencies, good gain and the ability to maintain higher signal to noise ratio over the whole of the operating range frequencies. In the beginning, the aim of this MRes project is to design, build and evaluate a dual-band reconfigurable antenna, and assess if it can be adapted to a smoother frequency adjustment, to achieve one-band moving in a big range of frequencies. This project is partly funded by L3-TRL Technology
