Image Innovation is advancing quicker than ever. As technology advances, it enables even faster change and progress, causing an acceleration of the rate of change, until eventually, it will become exponential.  Engineers and researchers that don’t stay aware of some of the significant-tech patterns take the risk of being abandoned. Understanding the key patterns will enable individuals and researchers to plan and embrace opportunities. There are many such technologies that have already made their prominent mark in 2019 and are only a few more applications away from becoming mainstream like 5G. Artificial Intelligence is one of the fast-growing technology for the future. The technology, with its potential to mimic the human brain, has offered numerous opportunities to different areas. Distributed ledger technology such as artificial intelligence (AI), blockchain, virtual and augmented reality, and Quantu

Practical Microstrip and Printed Antenna Design Book Cover My new book: “ Practical Microstrip and Printed Antenna Design ”, is all set to be released by end of this month (March 2019). The book covers the topic of microstrip antennas from roughly three vantage points: printed antenna fundamentals, antenna design technique, and design of real-world application-based antennas. This comprehensive resource presents antenna fundamentals balanced with the practical design of printed antennas. Microstrip and printed antennas are used in radars, aerospace systems, internet of things (IoT), satellite systems, 5G networks, MIMO, automobiles, and mobile phones. Supported with essential equations and illustrations, this practical book helps evaluate various design aspect of the antenna. Based on several years of my research in antenna design and development for RF and microwave applications, this book offers in-depth coverage of microstrip and printed antenna design methodology for modern a


Over the past few year, machine learning has attracted the attention of antenna engineers. Generally, the process of antenna design requires to find out the EM characteristics of antenna by observing the current distributions through simulations. These EM properties are then used for the parameters optimization. Machine learning (ML) can be combined with simulations to design an antenna. The inclusion of artificial intelligence (AI) can give promising results in the field of antenna designing. In recent years, antenna synthesis or design optimization through evolutionary algorithms (EAs) has been applied widely. At present, differential evolution (DE) and particle swarm optimization (PSO) are top two popular algorithms in the antenna synthesis area. In smart antenna array, the objective of the gracefully degradation of the beamforming and beamsteering performance, can be achieved by reconfiguring the array when an element is found to be defective. This reconfiguration can be obtain

Smartphone Antennas

A smartphone built on a mobile operating system, with more advanced computing capability connectivity than a feature phone. The smartphones combined the functions of a mobile phone, media players, low-end compact digital cameras, pocket video cameras, and GPS navigation, high-resolution touchscreens, and web browsers. With more operators announcing their LTE network coverage and plans, many smartphone manufacturers are switching to LTE based phones. Long Term Evolution (LTE) is a radio platform technology that will allow operators to achieve even higher peak throughputs than HSPA+ in higher spectrum bandwidth. The prime objective of LTE is to provide high data speed. A typical smartphone along with important electronics component is represented in Figure.

RF/Microwave filters find wide application in communication systems, such as satellite links or wireless base stations. Microwave filters are passive devices employed to select a specific band of the frequency spectrum. Depending on the spectral region that is selected or rejected, they are classified in low-pass filters, high-pass filters, band-pass filters or band-stop filters. Passive devices at the output stage of the communication system must be able to deal with very high power signals. Because of that, waveguide technology is the ideal choice to implement these devices. This work presents the design of a different kind of waveguide-based filter. Working Principle of Filter? So, what is magic behind filter? How does it reject signals and pass others? In order to understand this, let us first go through the concept of mismatch. When there is perfect impedance match between the input impedance of system with output load impedance, maximum energy transferred from input to outp


The switching is required in many applications at low as well as at high frequency. RF MEMS switches are the specific micro mechanical switches that are designed to operate at RF to mm-wave frequencies. MEMS switches usages some mechanical movement to achieve a closed or open circuit in the Radio Frequency transmission lines. GaAs FET switches do not have sufficient isolations to minimize cross interference and signal jamming from channels is close proximity.  MEMS switches provide  high isolation  when open,  low insertion loss  when closed, and can be operated at low power consumption. Because of electromechanical isolation, RF circuit doesn’t leak or couple significantly to the actuation circuit. MEMS are small in size hence it occupies less space in circuit designs so that which was the most required device in the communicating world. Radio Frequency Micro Electro Mechanical Switches (RF MEMS) classification depends on the type of actuation, deflection axis, contact type, circuit
