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 were
shown in Fig.15 and Fig.16.This was the best result
that has been obtained compared to both single patches
antennas previously.All measurement data for 1x2
patch array antennas are tabulated in Table 4.
