| Abstract: | In this paper,the dependence of circular aperture antenna near-field gain on measurement distance is derived using near-zone power equation.Numerical value results of near-field gain error correction are calculated for circular aperture general Taylor displacement distribution and exp distribution. A method of removing ground reflection error is discussed,in slant test fields ,a simply method reducing ground reflection is raised. At last,the test examples are reported to verify correctness of theory analysis and calculation. |
