Hi,
1. The problem statement, all variables and given/known data How can I calculate the magnetic H field for a rectangular loop antenna (L x W) at a distance of x, which is made from copper tape with 30 um thickness and width of the tape from 1 to 5 cm. For the same antenna made of wire I applied next formula: H=(I*L*W)/(4π√((L/2)^2+(W/2)^2 +x^2 ))*(1/((L/2)^2+x^2 )+1/((W/2)^2+x^2 )) (RFID Handbook Second Edition 4.1.1.1 Path of field strength H(x) in conductor loops pp 65) 2. Relevant equations I need an formula for magnetic H field for a rectangular loop antenna (L x W made from copper tape) or formula for calculating the magnetic H field for a rectangular conductor? 3. The attempt at a solution I tried this solution but I do not know if it is the best approach http://www.ntmdt.com/spmbasics/view...ctangularwire PS: I sorry for my bad English
