RF Designs and Simulations

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...

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. More Detail: Microstrip and Printed Antenna Design

The helix antenna is a travelling wave antenna, which means the current travels along the antenna and the phase varies continuously. Helix antennas (also commonly called helical antennas) invented by John Kraus give a circular polarized wave.  Helix antennas are referred to as axial-mode helical antennas. The benefits of this helix antenna are it has a wide bandwidth, is easily constructed, has real input impedance, and can produce circularly polarized fields. There are two mode of circular polarization in helix antenna. Left handed helix antenna:  In left handed helix antenna if you curl left hand fingers around the helix, thumb would point up. The waves emitted from this helix antenna are Left Hand Circularly Polarized. Right handed helix antenna:  In right handed helix antenna if you curl right hand fingers around the helix, thumb would point up. The waves emitted from this helix antenna are Right Hand Circularly Polarized The minimum number of t...
