The results of the proposed antenna with advantages of low profile, broad bandwidth, high radiation gain and efficiency, simple design and easy of manufacture, and cost effective make it a latent candidate for 5G millimeter-waves applications.

This work elaborates a dual-band antenna which finds its applications in mobile and satellite communication systems within the context of 5th generation (5G) technologies. The proposed antenna is designed by using semi-flexible substrate material Roger/RT duroid 5880 with an overall dimension of $15\ \text{mm} \times 15\ \text{mm} \times 0.79\ \text{mm}$ . The antenna structure is composed of dual circular patches along with elliptical patch, which is further loaded with two elliptical slots. The proposed antenna has the capability to operate from 25.8 – 29.9 GHz and 41.8 – 52GHz with central frequencies at 28 GHz and 44 GHz used for mobile and satellite communications, respectively. The proposed propagation device includes various advantages including its compact size with low geometric complexity, high gain and wide operational bandwidths which makes it good potential candidate for mm-wave applications and 5G communication systems.

An Ultra-wideband antenna for 5G V-band applications was proposed in this work. A conventional circular patch antenna was modified by using two set of fractal patches to increase the operational bandwidth of the antenna. While a circular slot was utilized to adjust the radiation pattern of the proposed work. The antenna offers an ultrawideband of < 30% with reference to the central frequency of 65 GHz. Moreover, the broadside radiation pattern, high gain and efficiency will make the proposed work a strong candidate for wideband applications using V-band spectrum.

In this paper, an umbrella-shaped patch antenna for future millimeter-wave applications is presented. The proposed antenna resonates at multiple frequency bands at 28 GHz, 38 GHz, and 55 GHz (V-band) that have been globally allocated for 5G communications systems. The proposed antenna is designed using Rogers RT/duroid 5870, with a thickness of 0.79 mm. The antenna has an overall size of 8 mm × 8 mm with simple geometrical structure, compact size, multiband operation, high gain, and efficiency.

In this work, a wideband microstrip patch antenna was designed for V-band applications. The antenna was designed by using substrate material of Rogger/RT duriod 5880 having overall dimension of 12mm × 13mm × 0.508mm. The proposed design shows the impedance bandwidth of 63GHz to 74GHz, along with that the proposed antenna offers a very high of > 9.5dB in the bandpass region. The proposed work offers a good combination of compact size, wide operational band, simple geometrical configuration, and high gain which make it potential candidate for 5G communications in V-band.

Over the years search engines have become more efficient in delivering relevant pin pointed results. For digital marketers that means more hard work because the actual metrics used to measure the content relevancy and quality are not yet disclosed by the search engines. The paper discusses a new technique named All in Title Query Result Analysis for identifying keywords with low competition. The posts written for such keywords would rank without any off-page search engine optimization. The research spans to almost 36 months of data taken from Google Analytics. The results show the supremacy of the new technique that can help new digital marketers or startups to launch digital platforms with reduction in the off-Site search engine optimization cost.

Narrowband Internet of Things (Nb-IoT) has emerged as one of the most promising wireless technology for the Internet of things. IoT devices have resource constraints that require novel techniques to optimize the devices' connectivity with the base station. Device to device connectivity is one of the promising solutions to form the IoT devices network with robust connectivity. The paper presents a technique that finds the potential relay device for an IoT device based on the least distance, the least bit error rate (BER), and the least power loss. Based on this combination the transmitting power can be reduced and the battery life of the IoT device can be improved. Simulation results demonstrates the supremacy of our proposed technique.

A CPW (Co-Planer waveguide) feed dual band slot antenna with frequency reconfiguration technique is presented in this paper. Frequency reconfiguration mechanism is performed between WiMax (worldwide interoperability for microwave access) and WLAN (wireless area network) systems. The propose designed antenna, consists of stubs of T-shaped and inverted T-shaped. Reconfiguration is achieved by placing respective stubs on different layers of the antenna i-e T-shaped is placed at the top layer which generates WiMax frequency band at 3.3-3.45 GHz (IEEE 802.16) and inverted T-shaped stub is placed at the bottom layer gives the WLAN frequency band at 2.2-2.45 GHz (IEEE 802.11).
