| Summary: | The growing demand for wireless communication services stimulates demands of high speed of wireless system in future. To accomplish these demands, the use of millimeter wave bands appears inevitable due to the very large amount of spectrum that could be made available. Hence, designing antennas capable of working at a high frequency range is becoming a trend of current research. Future technology is also moving towards 5G antennas. Many researchers are working on V-band antenna for wireless applications and the narrower bandwidth and lower gain are reported as main challenges in design. A novel V-band antenna configuration is modeled for multiband/wideband application. Multiband and wideband stack series array antenna are designed for the future 60 GHz in 5G application. Dual-layer substrate Technology is utilized in order to achieve a higher bandwidth which is needed to cover the V-band electromagnetic spectrum of 50 -70 GHz. Total of 25 antenna array configurations are simulated and analyzed to develop the model. Proposed antenna can resonate at single band of (60 GHz), dual band (57 GHz and 67.5) and triple band (54.82, 60.8 and 67.647 GHz).The bandwidth of 14.836 GHz (53.33-68.186 GHz) and the gain of 13.05 dB are achieved by proposed antenna configurations. Simulated return loss, and gain over the number of elements in upper/lower patches have been analyzed and presented. The proposed array antenna provides better gain, wide band width and higher efficiencies. All the proposed antenna configurations have shown good candidates for 5G millimeter wave (mm-wave) application. However, to fabricate and test at 60GHz antennas, facilities with good resolution are not available. Hence, same modeling of single, dual, and triple bands as V-band are also designed, simulated and tested at Ka-band (28GHz). The simulation results and the test results of Ka-band antenna were found a good agreement, in terms of single band, dual band and triple band. However, in the fabrication results, resonance frequencies shifted towards in the right direction. |
