Question

(12 pts) Assume you have copper tube of diameter 2 cm. Design an antenna that operates at 300 MHz with maximum radiation at 0 = 0° (as near as you

can). a) Does your loop have constant or non-uniform current? b) What is the radius of your loop? c) What is the radiation resistance of your loop? d) What is the directivity at theta= 0°? e) Is your loop self-resonant? If not, what capacitance (in parallel) or inductance (inseries) must be added to resonate the loop? f) Explain can you use a copper tube instead of a solid copper wire.
