“…The Web of Science includes more than 10,000 studies on the design of compact devices for wireless communications, so compact is of great importance to integrated circuits. In [12] and [13], the authors designed the embedded filters, the broadband transmitter is designed in [14], and the multi-band antennas are devised in [15], [16]. They are located in the RF front-end module of wireless communication, which can include integration with other circuit devices expediently.…”

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.

“…The FCC has designated a sub-6 GHz (3.2 to 6 GHz) frequency band for 5G wireless communication since it can provide improved spectral efficiency in the available spectrum and facilitate network development in urban areas [3]. As portable devices are becoming lighter and thinner by the day, a typical MIMO antenna for 5G devices should meet specified criteria like compact structure with high gain, steady radiation pattern, and low envelop correlation [4]. The most effective way to make MIMO compact is to replace multiple fixed-performance antennas of MIMO with frequency-reconfigurable antennas, which provide coverage for several wireless applications on the same platform based on switching conditions [5].…”

This paper demonstrates a low-profile, wide-band, two-element, frequency-reconfigurable MIMO antenna that is suitable for diverse wireless applications of 4G and 5G such as WLAN/Bluetooth (2.4-2.5 GHz), WLAN (2.4-2.484 GHz, 5.15-5.35 GHz, and 5.725-5.825 GHz), WiMAX (3.3-3.69 GHz and 5.25-5.85 GHz), Sub6GHz band proposed for 5G (3.4-3.6 GHz, 3.6-3.8GHz and 4.4-4.99 GHz), INSAT and satellite X-band(6 to 9.6 GHz). Proposed MIMO favour effortless switching between multiple bands ranging from 2.2 to 9.4 GHz without causing any interference. Both antenna elements in a MIMO array are made up of a single module comprised of a slot-loaded patch and a defective structured ground. Two PIN diodes are placed in the preset position of the ground defect to achieve frequencyreconfigurable qualities. The suggested MIMO antenna has a size of 62 ×25 ×1.5 mm 3 . Previous reconfigurable MIMO designs improved isolation using a meander line resonator, faulty ground structures, or self-isolation approaches. To attain the isolation requirements of modern devices, stub approach is introduced in proposed design. Without use of stub, simulated isolation is 15dB. The addition of a stub improved isolation even more. At six resonances, measured isolation is greater than 18 dB, the computed correlation coefficient is below 0.0065, and diversity gain is over 9.8 dB.
