A compact T-shaped network for decreasing the port-to-port coupling between two strongly coupled antennas is investigated. The proposed circuit comprises of a pair of transmission lines followed by the T-shaped lumped element network connected between the two feeds of the antenna. Finally, a simple L-section matching circuit is added to each port to retune the input impedance matching. The proposed...
In-band full-duplex relays transmit and receive simultaneously at the same center frequency, hence offering enhanced spectral efficiency for relay deployment. In order to deploy such full-duplex relays, it is necessary to efficiently mitigate the inherent self-interference stemming from the strong transmit signal coupling to the sensitive receive chain. In this article, we present novel state-of-the-art...
In an in-band full-duplex system, radios transmit and receive simultaneously in the same frequency band at the same time, providing a radical improvement in spectral efficiency over a half-duplex system. However, in order to design such a system, it is necessary to mitigate the self-interference due to simultaneous transmission and reception, which seriously limits the maximum transmit power of the...
