This paper proposes a solution to control the polarisation of the ASA independently from the feeding point position. It also allows an easier impedance matching of the antenna, and thus compact size and broadband behaviour. The concept of a polarization diversity antenna, based on this antenna solution, is then proposed TANGENTIALLY FED BROADBAND ANNULAR SLOT ANTENNA FOR WLAN ...

Four Ports Wideband Pattern Diversity MIMO Antenna . Ramling P. Manurkar α & Veeresh G. Kasabegoudar σ. Abstract- In this paper a broadband four ports MIMO antenna with pattern diversity is presented. To obtain pattern diversity, four microstrip feeding lines are printed on one side of the substrate where as the modified ground plane is

A compact asymmetric coplanar strip (ACS)-fed ultra-wideband (UWB) antenna for diversity applications is presented. The proposed antenna is composed of two circular radiating elements and orthogonal ACS-fed mechanisms to achieve diversity performance across the UWB from 2.66 to 11.08 GHz, and occupies a very compact size of 28.5 × 28.5 mm2. By introducing a rectangular stub diagonally between ...
