For the upcoming Sixth Generation (6G) and beyond wireless communication technology, the specification features substantial propagation rates, doubled connection density capability, massive information capacity, seamless sensing, and localization precision, which is a critical leap and mainstream tendency in comparison to the full-coverage Fifth Generation (5G) counterpart. Therefore, improving the spectrum efficiency by means of convergence, aggregation, and sharing technology to accommodate the challenging requirements of a prospective 6G network will be the primary consideration. In this circumstance, the research on concurrent dual-band transmission bears the brunt.First and foremost, this work suggests and demonstrates a novel method for concurrent dual-band transmission with merely one radio frequency (RF) front-end and local oscillator. Essentially, the suggested concurrent dual-band front end has its foundation in the standard multiport interferometric layout for single-band execution. Compared to the traditional methods based on the super-heterodyne or homodyne structure to achieve multiband transmission, the multiport architecture provides remarkable superiority in relation to frequency reconfigurability, fabrication straightforwardness, and budget-friendly manufacturing expense, coupled with energy conservation. Meanwhile, diode networks with intermediate frequency (IF) input signals are employed instead of variable impedance loads in a traditional multiport modulator to generate RF signals at the desired center frequencies. Additionally, signals with distinct data information will be intermingled into both RF channels owing to the linear property of a multiport network. To this end, prior to the modulation of IF input signals, the initial data sequences are reversely converted using an inverse matrix arithmetic. Therefore, this architecture allows for the effective modulation of these two groups of primary data streams into particular RF channels for communication with less inter-channel interference. In addition to theoretical analysis, simulations and experiments have been used to study and validate this novel concurrent dual-band transmitting front-end using M-quadrature amplitude modulation (QAM) signals. All results show outstanding dual-band concurrent transmission performance with significant dimension and biasing power reductions.On the other hand, based on a similar topology, an efficient and environmentally friendly multiport interferometric topology is also provided in this work for the purpose of enforcing concurrent dual-band transmission with digital predistortion (DPD). The proposed transmitter front-end is concise and comprises two uniform back-to-back multiport networks motivated by a unique local oscillator (LO) throughout a multilayer power divider (PD). Our proposed design dramatically decreases expenditure, overall biasing power, and the number of components compared to conventional architectures that rely on RF mixers. Moreover, to assure performance, the mere LO source can also successfully restrain the increase of intermodulations between the transmitting route and the DPD feedback pathway. More specifically, the proposed layout functions in harmony with existing DPD algorithms to mitigate interference from neighboring channels and in-band and cross-band distortion. Excellent predistortion performance is demonstrated by the experimental results in simultaneous dual-band and single-band transmissions. For instance, in all examined circumstances, the average error vector magnitude (EVM) with DPD enhances just 0.17% more than the original undistorted signals.In addition, the technology responsible for multiband simultaneous transmission and reception on the equivalent frequency bands has also been investigated and discussed. We report an in-band full-duplex dual-band front-end based upon single-core multiport interferometer collocation with hybrid coupler networks. As far as we are aware, this is the first proposal for simultaneously performing transmission and reception in the same frequency bands as of yet in response to the drawbacks of the above approaches. The proposed architecture can function flawlessly in the circumstances of low LO power consumption with 0 dBm. Meanwhile, the superior anti-interference capability enabled the transceiver system to be seamlessly operationalized at a 0.82 gigabit-per-second (Gbps) data rate. Its outstanding communication performance has been proven in different experimental scenarios; the measured bit error rate (BER) can be less than 0.01 and 0.02 for 16-QAM and 64- QAM orthogonal frequency division multiplexing (OFDM) signals in dual-band operation. Therefore, we can conclude that this architecture is cost-effective with ultralow energy consumption, enabling efficient communication performance with an extremely compact size and straightforward construction.
