Presently, a single compact antenna is expected to operate in multiple frequency bands, so that it may be used for multiple applications. In this regard, a compact asymmetric coplanar strip (ACS) fed monopole antenna was designed to operate in LTE band-40 and 5G mid band frequencies. To achieve the desired dual band frequency, meander line radiating structure was used. The uniplanar design with the ACS feed considerably reduced the antenna size to 19.25 × 10.5 × 1.6 mm3. This miniaturized dual band antenna can be easily integrated into circuit boards. The measured and simulated results provided a reflection coefficient (S₁₁) < –15 dB, which made the antenna suitable for LTE band-40 and 5G mid-band communication applications.

Smart grid is an intelligent power distribution system that employs dual communication between the energy devices and the substation. Dual communication helps to overseer the internet access points, energy meters, and power demand of the entire grid. Deployment of advanced communication and control technologies makes smart grid system efficient for energy availability and low-cost maintenance. Appropriate algorithms are analyzed first for the convenient grid to have proper routing and security with a high-level of power transmission and distribution. Information and Communication Technology plays a significant role in monitoring, demand response, and control of the energy distribution. This paper presents a broad review of communication and network technologies with regard to Internet of Things, Machine to Machine Communication, and Cognitive radio terminologies which comprises 5G technology. Networks suitable for future smart-grid are compared with respect to standard protocols, data rate, throughput, delay, security, and routing. Approaches adopted for the smart-grid system has been commended based on the performance and the parameters observed. ©2019. CBIORE-IJRED. All rights reserved

Summary This work aims to provide an electrically small reconfigurable antenna with modification in the radiating strip length to switch between 5G mid‐band and 4G band‐40 application. Initially, the length of the radiating strip is designed to operate at 3.5 GHz for 5G mid‐band applications. Using switch configuration, the length of the radiating strip is modified so that the antenna's resonant frequency shifts from 3.5 GHz to 2.32 GHz, which can be operated at 4G band‐40. The effective radiation remains the same at two resonant modes. In terms of size, the proposed antenna geometry is (16.5 × 10.5 × 1.6) mm3. The designed antenna with an electrical length of 0.7014 mm is electrically small in size in comparison with the works of literature. Antenna structure provides a gain of 0.69 dBi and 1.35 dBi at resonant frequencies 2.32 GHz and 3.5 GHz, respectively. The geometry of the antenna is straightforward, and the prototype is fabricated on a low‐profile FR4 substrate. The simulated results are validated experimentally.
