“…It can also enhance the availability, reliability and survivability of the network, which are the key requirements for disaster rescue scenarios. HetNets take full advantage of the complementary characteristics of different network tiers, and thus become an inevitable trend for future development of information networks [37].…”

In 5G mobile communication systems, massive multiple-input multiple-output (MIMO) and heterogeneous networks (HetNets) play crucial roles to achieve expected coverage and capacity across venues. This paper correspondingly addresses software-defined network (SDN) as the central controller of radio resource management in massive MIMO HetNets. In particular, we identify the huge spatial domain information management and complicated MIMO coordination as the grand challenges in 5G systems. Our work accordingly distinguishes itself by considering more network MIMO aspects, including flexibility and complexity of spatial coordination. In our proposed scheme, SDN controller first collects the user channelstate information in an effective way, and then calculates the null-space of victim users and applies linear precoding to that null-space. Simulation results show that our design is highly beneficial and easy to be deployed, due to its high quality of service performance but low computation complexity.

“…The feed source is located in another focus of the hyperblolid. Rectangular aperture pyramidal horn antenna is as a Cassegrain antenna feed source [8] that can achieve long-range detection of insulator and reduce the radiated interference of the sky and other insulators in the vicinity. When the combined antenna measures insulators, the microwave radiated from insulators can be seen as parallel.…”

Insulator contamination threatens grid safety. And insulator pollution detection can prevent accident occurrence. An invented insulator pollution detector based on microwave radiation is introduced in the paper. The result of testing on-site high-voltage insulator pollution with the detector compared with ESDD and NSDD. And the comparison results indicate the insulator pollution detector can test high-voltage insulator pollution.

“…It has some obvious advantages such as the simple structure, easy feed, relatively wider bandwidth and higher antenna gain. Manufacturing of the planar rectangular waveguide is now possible thanks to the developing of substrate integrated waveguide (SIW) technique, which has been widely used in the design of microwave circuits [1][2][3][4][5] and antennas [6][7][8][9][10] because of its lower profile and easier integration so as to gradually replace the traditional cumbersome metal waveguide. Recently, the researches on the design of antennas adopting SIW have mainly focused on three aspects: (i) dipole element antennas and their arrays fed by SIW [11][12][13][14][15]; (ii) slot array antennas using SIW techniques [16][17][18][19][20]; and (iii) H-plane horn antennas based on SIW discussed in [21] in detail and the corresponding arrays are also presented to improve the antenna gain.…”

A printed H‐plane horn antenna with loaded composite E‐plane dielectric‐metal lens is proposed and analysed in this study. The loaded lens of this horn antenna, which is parallel fed through an Sub‐Miniature‐A coaxial connecter, is integrated on one printed substrate circuit board by utilising the substrate integrated waveguide (SIW) technique. To well illustrate the superiority of the proposed antenna, three types of antennas, namely an SIW H‐plane horn antenna without any load, an SIW H‐plane horn antenna only loaded with the dielectric slab, and the proposed SIW H‐plane horn antenna loaded with both dielectric slab and E‐plane metal lens (dielectric‐metal composite lens), are manufactured, measured and analysed. Compared with the horn antenna only with a loaded dielectric slab, the proposed antenna with dielectric‐metal composite lens achieves a higher gain of more than 2dB in the operating bandwidth. Besides, the antenna has a relatively lower profile and smaller size, which makes the proposed antenna more easily to be fed, integrated and form arrays.
