Description

Welcome to the most comprehensive and clear-cut Udemy course on RF and Antenna Fundamentals, designed specifically for Telecom Professionals, IT Network Engineers, and Wi-Fi Enthusiasts. In a world that runs on wireless connectivity, not understanding RF is like an electrician not understanding electricity. Whether you're deploying a corporate WLAN, deploying & troubleshooting cellular signals, designing IoT networks, or simply trying to fix your home Wi-Fi, the principles are the same. This course strips away the complexity and gives you the practical, foundational knowledge you need to confidently work with any wireless technology.We cover everything from wave behavior and propagation modes to the critical math and antenna theory you need to design, deploy, and troubleshoot real-world wireless systems like Wi-Fi, cellular networks, Microwave Links and more. Whether you're preparing for a RF certification (like CWNA, CCNA Wireless), advancing your career, or fueling a personal passion, this course provides the solid foundation you need.Here is the outline of the course: Section 1: IntroductionGeneral Overview of RF Signal Transmission & ReceptionWhat is Frequency, Wavelength & Phase Difference?Frequency Range of RF SignalsSection 2: The Behavior of an Electromagnetic WaveWhat is an Electromagnetic Wave?Reflection and RefractionScattering, Diffraction & AbsorptionMultipath PropagationSection 3: Radio Wave Propagation — Modes, Frequencies, and Practical ApplicationsGround Wave Propagation (Up to 3 MHz)Sky Wave Propagation (3–30 MHz)Line of Sight (LOS) Propagation (Above 30 MHz)Non-LOS Propagation in VHF & UHFTropospheric Communication in VHF & UHFSHF (3–30 GHz) & EHF (30–300 GHz) Wave PropagationSection 4: Modulation/Demodulation in RF CommunicationModulation/Demodulation — Fundamental Requirement for RF CommunicationWhy We Use Modulation?
