A simple antenna structure able to simultaneously generate two different polarisation and radiation modes is proposed. In addition to a good impedance matching all over multiple bands, antennas based on the proposed geometry can exhibit a linearly …

In this letter, a planar ultra wideband (UWB) antenna suitable for the integration in wireless universal serial bus (USB) dongles is described. The antenna has a bandwidth equal to 2 GHz from 3 GHz up to 5 GHz with return loss values below -10 dB in …
