Isn't the impedance to be 73 ohm for 1/2 wave dipole??if not this impedance that is to be used then can someone guide me through the procedure to calculate the input impedance??

thanks you have convinced me that the balanced antenna requires a balanced cable. So, what is the easiest way to make the balun using a coax of 75 ohm for a center fed half wave dipole??
Actually i have made three antennas and the boom element is wood!! I am waiting a lab appointment date to test the antennas!!Most probably i will test the antenna by this week.
I have not implemented the impedance matching. I have just connected the driven element to the coax cable of 75 ohm. Do...
Thank you for replying!!from what i can gather, you are saying these for a practical antenna!!here it is a simulated antenna pattern from a matlab code by balanis. I would like to understand the field pattern plot shown for interpretation!! I understand that the field plot uses the poynting...
The attached photo is that of a field pattern for a yagi antenna.Result of a graph when running the code from balanis on Yagi_Uda.m. My problem is that I cannot understand the graph that I am having.I understand that it is a plot of E-field agains theta and H-field against phi. But I cannot...
thx for trying to help!!my problem is that i dnt have equation for azimuth and elevation for yagi. I have seen equation for others but they are for linear and yagi is not linear.
The calculator does not recommend to use a 6 element yagi for such a frequency. I have google for 2 months already...
Hi, i am doing a project on yagi antenna and would like to know the formula for calculating azimuth,elevation and array factor as these are needed from what ive read to draw the radiation pattern.
i hav chosen a freq of about 900MHz and i am starting with a 6 element yagi.
I would also like to...
