dc.description.abstract Nowadays with the limited spectrum bands the mobile operators have been challenged to deliver multimedia applications with higher data rates, low latency and better quality of service of mobile communications to a growing number of users. This has led to a big number of inventions and technology advancement in past decades which is the prime goals of the upcoming 5th generation (5G) mobile networks. The millimeter wave (mmWave) is a suitable candidate for 5G with its high frequency range from 30 GHz up to 300 GHz. This thesis aims to design, analyze, simulate and compare the single and array elements of printed dipole, microstrip patch and planar inverted-F (PIFA) antennas regarding to their performances at the same operating frequency of 28 GHz using computer simulated technology (CST) microwave studio electromagnetic simulator. The comparison is based on simulated results of radiation pattern, gain, directivity, VSWR, return loss and e ciency. Based on the results obtained 4 1 array antennas have maximum gain and directivity of 9.87 dBi and 10.12 dBi for printed dipole antenna, 12.09 dBi and 12.37 dBi for microstrip patch antenna, and 9.79 dBi and 9.812 dBi for PIFA, respectively. The VSWR and return loss value, respectively, is found to be 2.4 and -7.57 dB for printed dipole array antenna, 1.09 and -27.37 dB for microstrip patch array antenna, and 2.6 and -6.5 dB for array of PIFA. The radiation e ciency for printed dipole array antenna is -0.248, for microstrip patch array antenna is -0.275, and for array of PIFA is -0.18. In this regard, the analysis shows that the microstrip patch antenna is quite capable of achieving the highest performances and represent an obvious choice for mobile applications. Moreover, to achieve an optimum design parameter the microstrip patch array antenna is also simulated with varying values of the substrate height, substrate thickness, patch length and patch width. The e ect of these parameters on antenna performance is analyzed. en_US
