A review on the recent advancements made on filtennas are presented in this paper. RF fronts ends continue to generate a lot of research attention in communication systems due to the effect it has on the overall bit error rate and SNR. Issues such as compactness, interference and noise are addressed by embedding the bandpass filter into the antenna to form a filtenna. Designing a filtering antenna has its own challenges also. Various techniques (synthesis approach, T shaped resonator or slots.) are being used to design filtennas in order to achieve “weak coupling between the feed and the radiating structure” hence yielding better selectivity. The filter-antenna gain results compared to that of the conventional antennas show better rejection of the out of band gain. This helps reduce interference with adjacent frequency band. This paper presents a review of the techniques, challenges faced and potential research trend in filtering antennas.

AbstractA tunable balanced bandpass filter (BPF) with a good common-mode (CM) suppression based on slotline resonators is proposed in this letter. Two novel stub-loaded slotline resonators (SLSRs) terminated with varactors are designed to obtain tunable differential-mode (DM) responses. It is found that a high and wideband CM suppression can be achieved by employing balanced stepped-impedance microstrip-slotline transition structures. Moreover, the DM passbands are independent from the CM ones, which can significantly simplify the design procedure. To validate the design theory, a compact tunable balanced BPF with an operating frequency band ranging from 3.09 GHz to 3.6 GHz is designed and fabricated. The measured results are found to agree well with the simulated ones.
