Fig.12 shows the simulation results for 45º and -45º
dual-polarized array antennas with VSWR and return
loss of 1.299 and -17.72 dB respectively at the
resonant frequency.Again,this proves that the
combination of more patches in the array antenna can
improve the VSWR and RL.Fig.13 shows the
radiation pattern for 45º and -45º polarized dual-
polarization array antenna.
4.Measurement Results
The same parameters involve in the
simulation were measured using Advantest R3767 CG
Network Analyzer.The measurement result has been
summarized in Table 3 for the 45 º and -45º polarized
single antenna,respectively.The return loss is below -
10 dB within the frequency range between 2.51-2.61
GHz,corresponding to a bandwidth of 4.22%.
Fig.14 shows the measured with -49.125 dB
of return loss for dual-polarized patch array antenna.
The measurement results of 1x2 patches arrays wer
