Abstract (en)
When a multi-port slot antenna exhibits disjoint ground planes for the different ports due to the arrangements of the slots, a salient idea is to use high impedance lines loaded by discrete RF inductors for connecting the different grounds related to the different ports of the multi-port slot antenna. The inductor exhibits a very low impedance from a Direct Current (DC) point of view and very high impedance (several hundreds to few kilos of Ohms) at the operating Radio Frequency (RF). Hence, this will achieve a continuous DC ground without affecting the RF performance of the antenna.
