Multi-Device Antennas

Student thesis: Master thesis (including HD thesis)

Nowadays it exists an ever-increasing pressure to reduce the form factor of the antenna while increasing or keeping acceptable efficiency, bandwidth and antenna isolation. Every time the size of the ground plane is modified, antenna engineers implement a new design.
However this fact provokes additional costs to the antenna design. Thus, portability of a fix antenna for different ground plane sizes might be worth. Moreover, isolation between antenna in MIMO systems is a big issue, specially for small devices operating at low frequencies. Then, the industry seek for innovative designs that can improve the performance of the classic top-bottom MIMO configuration.
Lateral designs are presented as a promising candidate. For these reasons, a comparison of two antenna designs over different ground plane formats is analyzed, leading to the conclusion that the portability of a lateral design provides very good performance if proper decoupling techniques are implemented.
