Abstract：A computing method based on plane geometry which is used to calculate the isotropy of E-field probe is purposed. And the generality and reasonability of the method have been proved through theoretical deduction and experiment validation. Based on the experimental results, it shows that the results difference between the new method and the one used in Standard IEEE-1309 is 0.01~0.08 dB. But through comparison of the new method to the one used in IEEE-1309, it shows that the method can not only evaluate the isotropy of E-field probe but also can have positive effects on the improvement of isotropy of E-field probe at the same time.
