Design and Analysis of Novel Antenna for Millimeter-Wave Communication

At present, the microwave frequency band bandwidth used for mobilecommunication is only 600 MHz. In 2020, the 5G mobile Communicationrequired about 1 GHz of bandwidth, so people need to tap new spectrumresources to meet the development needs of mobile Internet traffic that willincrease by 1,000 times in the next 10 years. Utilize the potentially large band-width (30 similar to 300 GHz) of the millimeter wave frequency band to provide higherdata rates is regarded as the potential development trend of the future wirelesscommunication technology. A microstrip patch implementation approach basedon electromagnetic coupling feeding is presented to increase the bandwidth of adual-polarized millimeter-wave antenna. To extend the antenna unit's impedancebandwidth, coplanar parasitic patches and spatial parallel parasitic patches areused, and a 22 sub-array antenna is developed using paired inverse feed technol-ogy. The standing wave at the centre frequency of 37.5 GHz is less than 2 GHz.The antenna array's relative bandwidth is 6.13 percent, the isolation is >30 dB, thecross-polarization is-23.6 dB, and the gain is 11.5 dBi, according to the norm.The proposed dual-polarized microstrip antenna has the characteristics of widefrequency bandwidth, large port isolation, low cross-polarization, and high gain.The antenna performance meets the general engineering requirements of milli-meter-wave dual-polarized antennas.
