Hii mam, can you please suggest a good reference paper for designing a patch antenna of frequency ranging 3 to 3.5 GHz using FR-4 Substrate of 1.6 thickness. It will be so thankful if you can do this, I am facing alot of problem in finding those papers.

[@EasyElectronics975]

I dont know exactly what to share, but i suggest checking IEEE

What is radiation? How is a transverse wave produced? What is refraction? Light and radio waves are electromagnetic waves comprising electric and magnetic field pulsations or variations in strength at each point in the space. It is a form of radiated waves of pulsating electric and magnetic fields. They are produced by accelerated electric charge which produce a transverse electric field which propagates outward from the accelerated charge. The radiated fields constitute a wave travelling through space. The fields don't travel, the wave does. The fields pulsate in strength. This is best visualised by a rope, one end of which is fixed to a wall and the loose end held some distance away. The loose end when moved up and down creates a wave travelling. Notice how the molecules of the rope near the wall have not travelled to the loose end. The snake-like shape in the form of a sinewave and travelling movement you see is the overall effect of the up and down movement of the molecules of the rope. The same happens with the strength of electric and magnetic fields of radio waves and light. There are no sinewaves in space! It is the strength of the electric field say, which we plot of a radio wave which has a pattern of a sinewave. When a radio wave or rather the fields of the wave encounter matter, they set into motion the atoms in the material. The acceleration they produce of the charges that make up the atoms and molecules in matter, produce electromagnetic waves and these are reradiated fields. The incident and reradiated fields combine to produce a resultant wave. These resultant waves constitute the fields in reflection and refraction. Before learning about sinusoidal currents, voltages and electromagnetic fields it would be instructive to learn about current and the conduction process at the fundamental level as in these two videos i. kzbin.info/www/bejne/ioXXpWVul5aXj9E and ii. kzbin.info/www/bejne/bnO0fpKurJeFnNE Engineers are so used to thinking and visualising currents as differential-mode in circuit analysis that they find it hard to switch their thinking to common-mode currents and its uses in designing high impedance antennas. They can be generated internally in circuits and in antennas such as the folded dipole antennas like the Yagi antenna. The last frame of video 1 contains in the References textbooks 3 and 4 which discuss antennas (dipoles) and wave propagation and includes topics on reflection, reradiation and scattering using the unified approach with the help of sequential diagrams. Also discussed in textbook 4 is the generstion of common-mode currents in two-wire cables which is useful in understanding the operation of the folded-dipole. Watch the following videos to get an idea of radiation by an accelerated charge and an oscillating charge.
