Abstract
The advancements in wireless communication systems need a low cost, minimal weight, and low-profile antenna arrays that are capable of providing high performance over a wide frequency band. In this regard, the patch antenna is considered as a candidate antenna type for 5G communication systems. However, the bandwidth of microstrip patch antenna (MSPA) is narrow; its directivity, gain, and radiation efficiency are low. Moreover, attempting to improve the performance of the MSPA by integrating a large number of patch antenna in the array leads to increased mutual coupling and reduced radiation efficiency, and directivity of the antenna. Therefore, to address these challenges, this paper presents the performance enhancement of MSPA array for 5G mobile applications. To achieve this, inset-feed impedance matching techniques, quarter-wavelength impedance transformer, and optimization of the parameters of different MSPA array structures have been simultaneously used. All the studied antenna structures are designed using FR-4 substrate with a dielectric constant of 4.4 to operate at 28 GHz and the performances have been analyzed using a CST antenna simulator. The simulation results show that directivity of the proposed single element, 2(\times )1, 4(\times )1, 4(\times )4, and 8(\times )8 rectangular MSPA arrays are 7.41 dBi, 9.451 dBi, 11.2 dBi, 15.8 dBi, 19.31 dBi; the bandwidths are 572 MHz, 575 MHz, 1394 MHz, 332 MHz, 368 MHz; the radiation efficiency is more than 95% for one-dimensional MSPA arrays and more than 80% for the two-dimensional MSPA arrays. As compared to designs reported in the literature, the proposed antennas show significantly improved performance.
