Preparing toward the new-generation communication by improving the capacity in the channel can be achieved by employing a MIMO system with polarization diversity means. This paper presents a low-profile $4 \times 4$ MIMO bidirectional antenna consisting of two composite antennas mounted on a ground plane. The composite antenna is constructed by stacking a notch antenna and a loop antenna on top...
This paper presents the evaluation of channel capacity for 4 × 4 MIMO system in indoor propagation environment at frequency 3.5 GHz and 2.6 GHz. The effect of an antenna with the beam radiation pattern on the capacity of the channel is shown by comparing the capacity with the dipole antenna as conventional antenna. The channel response in the simulation is modeled using ray tracing method and the...
