CONCLUSION
A new low-cost dual-polarized array of corner-fed patches is presented. Its advantages are small size, low cost, higher isolation, lower cross polarization, etc. The radiation patterns for both co-and cross polarizations are formulated and calculated. Its S-parameters are found by using the CADoriented EMN method for thin microstrip antennas, which combines the cavity model, the multiport network model, and segmentation and desegmentation techniques. The theoretical results are validated by comparison with experimental results. The measured isolation of the 4 = 4 array is 26.5 dB at 12.0 GHz, which is obviously better than that of the classical ones.
The dual-polarized array presented in this paper can be improved further by means of corrections in the feeder width and length, corporate feed design, etc. They are promising for practical applications.
