“…Substantial efforts [130]- [135] have been invested in the antenna design for the sake of enhancing the achievable antenna gain. Specifically, Mao et al [130] have designed a directional antenna equipped with a coupled resonator. Their design is capable of achieving 9 dBi antenna gain at a frequency of 5 GHz and it may also achieve as much as 10 dBi antenna gain at a frequency of 6 GHz.…”

In order to satisfy the power thirsty of communication devices in the imminent 5G era, wireless charging techniques have attracted much attention both from the academic and industrial communities. Although the inductive coupling and magnetic resonance based charging techniques are indeed capable of supplying energy in a wireless manner, they tend to restrict the freedom of movement. By contrast, RF signals are capable of supplying energy over distances, which are gradually inclining closer to our ultimate goal -charging anytime and anywhere. Furthermore, transmitters capable of emitting RF signals have been widely deployed, such as TV towers, cellular base stations and Wi-Fi access points. This communication infrastructure may indeed be employed also for wireless energy transfer (WET). Therefore, no extra investment in dedicated WET infrastructure is required. However, allowing RF signal based WET may impair the wireless information transfer (WIT) operating in the same spectrum. Hence, it is crucial to coordinate and balance WET and WIT for simultaneous wireless information and power transfer (SWIPT), which evolves to Integrated Data and Energy communication Networks (IDENs). To this end, a ubiquitous IDEN architecture is introduced by summarising its natural heterogeneity and by synthesising a diverse range of integrated WET and WIT scenarios. Then the inherent relationship between WET and WIT is revealed from an information theoretical perspective, which is followed by the critical appraisal of the hardware enabling techniques extracting energy from RF signals. Furthermore, the transceiver design, resource allocation and user scheduling as well as networking aspects are elaborated on. In a nutshell, this treatise can be used as a handbook for researchers and engineers, who are interested in enriching their knowledge base of IDENs and in putting this vision into practice.Index Terms-RF signals, wireless energy transfer (WET), wireless information transfer (WIT), simultaneous wireless information and power transfer (SWIPT), wireless powered communication networks (WPCNs), integrated data and energy communication networks (IDENs).an increasing research interest from both the electronic and communication engineering communities. C. Near-field Wireless Energy TransferAt the time of writing, resonant inductive coupling [35] and magnetic resonance coupling [36] emerge as flexible wireless charging options for electronic devices in the nearfield. Resonant inductive coupling based wireless charging relies on the magnetic coupling that delivers electrical energy between two coils tuned to resonate at the same frequency. This technique has already been commercialised for small electronic appliances [37], such as mobile phones, electric toothbrushes and smart watches etc. However, the coupling coils only support near-field wireless power transfer over a distance spanning from a few millimetres to a few centimetres [38], while achieving a power transfer efficiency as high as 56.7%, when operating at a frequency of 508 kHz [...

A differentially fed, dual‐band microstrip patch antenna with filtering response is proposed in this letter. By etching an H‐shaped slot at a rectangle radiating patch, two resonant modes of the patch antenna, as well as an additional radiation null between the two operation bands are generated. Besides, two symmetric open‐stub coupling feedlines (OSCFs) are introduced to differentially excite the antenna, which offer two extra radiation nulls outside the two bands. Thus, a dual‐band bandpass filtering response for the proposed antenna is obtained. Measurement results of the prototype show good agreement with the simulated ones. Stable radiation patterns with low cross‐polarization levels of better than 28 dB are observed. Besides, a deep roll‐off of better than 22 dBi for the realized gain is also obtained.

“…Thus, interference between antennas working at different bands still exists, which greatly influences the performances of communication systems. In recent years, antennas with filtering responses have become promising candidates to solve the problem, and most of them introduce filters into antenna feedlines [1][2][3][4][5], which makes it easier for integration with the whole system. Besides, the introduction of filters always contributes to good filtering responses.…”

“…In most designs of filtering antennas, very few of them can be applied in dual-polarized antenna systems with multi-band applications. At the same time, in most multiband antenna designs, filtering responses are not taken into consideration [2,14,15]. In view of this, a multi-band filtering antenna with dual-polarized performance is proposed in this paper.…”

In this paper, a multi-band patch antenna with bandpass filtering response is proposed. The antenna consists of two pairs of crossed dipoles, four Γ-shaped feedlines, and four steeped-impedance microstrip lines. With the introduction of Γ-shaped feedlines and U-shaped slots on the radiating patch, extra radiation nulls are induced, and four operation bands with band-pass filtering response are obtained. More importantly, the filtering response of the antenna is generated without any filtering circuits, which is easy to design for antenna engineers. Measured results of the prototype show that the proposed antenna has stable radiation patterns with low cross-polarization level of better than −26 dBi over the four operation bands. Good filtering response with deep roll-off can also be observed between different operation bands. Excellent radiating performances make it a promising candidate for 5G wireless communication systems.
