My thought exactly!

I've designed a standard pyramidal horn using the design procedure outlined in Balanis Antenna Theory - Analysis and Design, 3rd Ed. and used the dimensions from this design to ...

At a very low-level intuitive idea, consider that a very short pulse in time would have a very large frequency span. Similarly, a very large antenna (many wavelengths long) is typically very directiv ...

thanks for the reply.....too much to ask but can u tel me what i should sub in place of Ea(x,y).......Emaxhorn*cos(pi*x/A)*exp((-1i)*(k/2)*((x^2/le)+(y(l)^2/lh)))....wil this do?.......im gettin an an ...
