We also looked at the fundamentals of antennas for example, radiation pattern, half power beam width, first null beam width, side lobe levels and so on and then we also looked at simple expressions for directivity, gain as well as how to calculate reflection coefficient from the input impedance of the antenna and then how to Today, we will look at a very important parameter what is a link budget, how do we really decide, what should be the gain of the antenna or what should be the power transmitted, what should be the receiver sensitivity and so on and then we will start looking all these antennas one by one.
हमने एंटेना (Antenna) के मूल सिद्धांतों को भी देखा, उदाहरण के लिए, विकिरण पैटर्न, हाफ पाअर बीम विड्थ (half power beam width), फर्स्ट नल बीम विड्थ (first null beam width), साइड लोब (side lobe) स्तर और फिर हमने डिरेक्टिविटी, गैन (gain) के साथ-साथ रिफ्लेक्शन कॉएफिशिएंट (Reflection coefficient) की गणना करने के लिए सरल इक्स्प्रेशन (expression) को भी देखा।
