“…There are different methods to design a Filtenna [60]. First, we have the traditional one, in which the antenna and filter are designed separately and then a matching network is designed to connect them, like the work in [61].…”

multi-standard RF front-end is a critical part for current and future mobile generations, where the size, efficiency and the integration of the elements in the RF front-end affect the expectations of the standard performance, This chapter discusses the design of power amplifier in both handset and base station of 5G and beyond. Also, this chapter deals with the filters, antennas, and the integration between these elements. A filter-antenna integration has been studied here. A synthesis-based approach has been followed for the filter-antenna codesign, moreover, design of a differentially driven reconfigurable planar filter-antenna integration with high-gain and high-common mode suppression is proposed for 5G RF front end systems. Finally, an insensitive phased array antenna with air-filled slot-loop resonators is introduced for 5G mobile communications

“…I N order to reduce losses, complexity, size, and cost in a radio system, filtering antennas or filtennas [1] have been considered as an effective solution as the filtering function can be realized within the antenna structure. There are numerous techniques to design filtering antennas, which have been continuously developed in the last decades.…”

“…There are numerous techniques to design filtering antennas, which have been continuously developed in the last decades. As surveyed in [1], those techniques, for instance, include the implementation of feeding structures incorporated with bandpass filters, the utilization of defected ground planes, coupling resonators, substrate integrated waveguides, and multilayered structures.…”

In this paper, a dual-polarized filtering Fabry-Perot antenna (FPA) with high-isolation is proposed. It consists of a feed element of differential-fed dual-polarized square patch and a partially reflecting surface (PRS). The patch is capacitively coupled with T-shaped resonators and shorting-vias to obtain broadband characteristic and radiation nulls. The PRS structure is composed of two complementary metasurface layers are selected for achieving a positive reflection phase gradient within the broad frequency range. More interestingly, thanks to the frequency selectivity feature, the PRS significantly enhances the filtering characteristic of the FPA. For verification, a prototype of the proposed antenna operating at the 5.5-GHz center frequency has been fabricated and measured. The prototype with an overall size of ∼2.0λ min × 2.0λ min × 0.49λ min (λ min is the free-space wavelength referring to the lowest operational frequency) result in an impedance bandwidth of 17.1% (5.02 − 5.96 GHz) for 10-dB return loss and a high isolation of ≥ 45 dB. Moreover, the far-field measurements result in a good dual-polarized radiation with the peak gain of 13.0 dBi, cross-polarization level of ≤ -25 dB within the passband, and out-of-band suppression level of ≥ 20 dB.

“…Filtering antennas have attracted the attention of many researchers due to their multi-functional integration and compact structure [1,2]. Compared with the microstrip antenna, dielectric resonator antenna (DRA) has the advantages of high degrees of design freedom, high gain, and low loss [3][4][5] which is suitable for a variety of application scenarios.…”

A filtering dielectric resonator antenna (FDRA) using an inductive CPW (coplanar waveguide) feed structure is proposed. Simultaneously, a pair of slotline stubs are respectively loaded on the signal line and ground of the CPW feed structure, which is used to generate radiation nulls near the edges of the passband. Furthermore, the two radiation nulls can be controlled independently by adjusting the length of the loaded two pairs of slotline stubs. In addition, it is interesting that TE 111 mode is split due to the different loading effects of slotline stubs in feed network, thereby three resonances in the passband are formed. Finally, an FDRA with quasi-elliptic function response is realized without additional filtering circuit. The prototype of the FDRA operating at 3.53 GHz was fabricated and measured to verify the design validity. The measured results show that the impedance bandwidth is 13.6% (3.29-3.77 GHz); the gain is basically stable at 5.7 dBi within the passband; and the two radiation nulls are located at 3.05 GHz and 3.88 GHz, respectively.
