Abstract
In order to meet the requirement of nowadays communication systems, 5th generation (5G) wireless communication requires high data rate. A millimeter-wave microstrip patch antenna designed for 5G high-frequency band is presented in this paper. The performance of antenna is modified mainly by two notches at the junction of the patch and the transmission line. Modifying the length of notch is proved to be the preferred choice for adjusting the antenna performance because of its stability in parameter regulation. In simulation, the antenna achieves the bandwidth of 767MHz, which is centered at 38GHz. The final realized gain is 7.67dBi and both radiation efficiency and total efficiency are higher than 90%. The antenna performance is also good in two-element array. The gain of main lobe increases to 10.8dBi and 3dB angular decreases from 73.2º to 27.0º. The proposed design of antenna can be used in 5G wireless applications at the frequency of 38GHz. The research of this paper can enhance the development of wireless communication technology.
