Transmission lines question

Please I need an answer to that question :

If you want your matching to be broadband,i.e. work satisfactory over wide freq. range, would you place the matching impedance close to or far from the unmatched load?

Thanks in advance

Dear Darshkamal.

Your Question wasnt quite clear but,ways of achieving broadband matching is
1.Instead of using one single quarter wave transformer to match the load to the characteristic impedance. we use a cascade of quarter wave line sections of gradually varying characteristic impedances.Though zero reflection coeffficient is not possible with this method.the desing can be implemented for a specified maximum reflection coefficient acceptable under the frequency band of operation
2.tapered transmission line transformer with carying characterisitic impedance along its length. Various tapers can be applied such as linear, exponential etc.

Hope that helps
