The axial ratio as a function of the frequency is shown in
Fig.9. It is evident that the minimum axial ratio is occurred at
919 MHz. However, along the frequency range of 911-927
MHz, the acceptable axial ratio of less than 3 dB is
accomplished. At the frequency of 923 MHz, the axial ratio is
1.73 dB.
