“…To further simplify the design and improve the return loss in the working band, Yu et al proposed a planar FA based on SIW in 2011. The yagi antenna is used in this design, and fifth-order FA is obtained by combining the antenna with the SIW filter [66]. To further reduce the size, Yu et al in 2012 put forward an inductive window bandpass filter and coaxial collinear (COCO) antenna in Ku-band [67].…”

In recent years, with the rapid development of integrated circuits, the filtering antenna (FA) circuit of the substrate integrated waveguide (SIW) has attracted widespread attention in wireless communications. Numerous structures have been proposed to improve the performance of SIW FA. Hence, this paper presents the development and miniaturization trend of the SIW FA, and briefly introduces the structure and historical development of the SIW FA. In terms of the mode, multi-mode cavities and incomplete mode cavities are constructed. Multi-layer structures, special structures and the slow-wave technology are constructed in physical structure. Several methods and design examples of the SIW FA miniaturization are introduced from these two aspects. Based on the combination of the filter and antenna, the FA remains the advantages of the SIW structure, mainly including small size, low insertion loss, high quality-factors, and easy integration in planar radio frequency components. Therefore, it can further reduce the circuit, allowing SIW FAs to be applied in many aspects such as the 5G (5th generation mobile communication technology) and wireless local area network communications.INDEX TERMS Substrate integrated waveguide (SIW), filtering antenna (FA), multi-mode, incomplete mode, multi-layer, slow-wave technology.

“…However, an extra matching circuit is required between the antenna and filter to address the mismatching problems such as a degraded filter performance, especially at band edges, and an increased insertion loss of the overall systems [1]. Recently, in an effort to reduce the weight and size of the RF front-end system and in the pursuit of improved performance, there is an increasing interest in integrating the antenna and filter in a single compact module which has both the filtering and radiating functions, such as the work presented in [1]- [7]. These reported antenna filter integration work generally follow two approaches: (i) introducing external matching network between the antenna and filter; (ii) integration of the matching in the antenna element itself by discovering suitable connection geometry [6].…”

This paper presents a novel antenna that includes filtering functionality. The design approach is based on directcoupled resonator filter theory. In this approach, the filter can be integrated into the antenna itself using the antenna resonant elements as the resonators of the filter. The design principle can be applied to any desired frequency and physically realised using different types of antenna structures. In this example, a rectangular patch antenna integrated with four conventional square open-loop resonators is designed using a single layer microstrip to verify this antenna-filter design approach. In order to preserve the filter's characteristic, the radiation quality factor of the patch antenna is chosen the same as the external quality factor of the filter, and the coupling between the patch antenna and the last open-loop resonator is calculated using the theory for two conventional coupled resonators. The simulation results demonstrate this filter antenna design approach works well.
