Design of 2x2 rectangular patch array antenna on LTCC substrate at 60GHz / Yanti Iswa Ishak

This project is about the design of 2x2 array rectangular patch antenna with inset fed operating at 60GHz based on 4 layers low temperature co-fired ceramic (LTCC) technology. The defected ground structure, electromagnetic band gap, parasitic element structure and different spacing distance were used to evaluate the performance of the proposed antenna in terms of return loss, gain, directivity and bandwidth. The antenna was designed and simulated using CST Microwave Studio. The results showed that the proposed antenna have gain of 9.512dB, directivity of 9.355dBi and return loss of -47.794dB. Meanwhile when the spacing is varied to be more '.., the antenna cannot be tuned at the desired frequency. The proposed antenna with DGS structure has gain of 9.570dB, directivity of 9.411dBi and S11 of - 38.883 1dB. The proposed antenna with EBG structure has gain of 9.375dB, directivity of 9.533dBi and S11 of -49.651dB.
