Thank you for amazing lecture! I have a question in regards solution 1 and solution 2: we can use any of them equally, right? Should we always calculate them both?
@RFDesignbasics6 жыл бұрын
Both the solutions are correct but when We implement it using microstrip line we should prefer larger value of characteristics impedance over smaller value for the quarter wave transformer, so that line will be compact.

A very Good lecture Sir.... I have a doubt, 1.) when designing the d1 and Lambda/4, what should be the width of these two? Is both are of same width or different.... 2.) what should be the length and width of the section of the feedline which comes before lambda/4 which is 50 ohm feed (source side). Kindly help me, Sir.

If I am not wrong, you are talking about microstrip line design. Source side length can be anything. Width can be calculated using Microstrip line calculator and it will depend upon the characteristics impedance of the respective line.

Sir, Can you tell me, how can i find the complex impedance of antenna (Load Impedance), If source Imp. is 50 ohm and input impedance at the edge of antenna is 144 ohm. Kindly, please help me.

Connect a 50 ohm port and measure reflection coefficient and do the reverse calculation.

Thanks as always, Sir. Your video is great. May I ask a question please? About the pure real load impedance, did you mean that there's only a solution which is d=0.25? but what should I do with the rest of equation? Let say Zo is 75 and ZL is 40. So the r will be 0.304

If the load is purely resistive the question become easy and you may skip the calculation of d or you may take d as 0.5 lambda or it's multiple.
