Reconfigure 5G sub 6 GHz and Wi-Fi bands Micro-strip Antenna using hybrid slotting and mix substrate material techniques

In this paper Dual Band Multilayer Micro-strip antenna using LTCC (Low Temperature Ceramic co-efficient) and FR-4 materials for C-X- Band applications has been designed. The Proposed antenna is designed using two C type Slot inserted in top layer patch and five vertical slots design on middle patch. The properties of two materials LTCC and FR-4 substrates have been mixed to improve the radiation characteristics and return loss of design antenna from 4 to 6GHz. This antenna is used to improve the return loss and operating impedance bandwidth. The impedance bandwidth S11 • - 10dB achieves 34% of C-Band from 4.1 to 5.8 GHz and can be used in Wi-Fi bands and 5G sub 6 GHz. The Axial ratio bandwidth achieved • 1dB, so that design antenna included circular polarization characteristics from 4 to 6GHz. This proposed design provided return losses from - 10dB, to -52 dB. In this work has been simultaneously improved impedance bandwidth and axial ratio bandwidth. The linear and circular directivity has been improved simultaneously.
