Purpose: The study and design of flexible patch antenna with different inset gap width fabricated on RT duriod 5880 substrate for fifth generation wireless application is presented in this article. The patch is composed of slits along the length and width separated by copper ground plane on backside and is directly fed by inset feed. The antennas resonated at multiband characteristics with better return loss (RL) suitable for fifth generation wireless and other indoor communication based applications. Radiation patters are nearly broadsided with a heart like shape for resonant band of frequency. Design/Methodology/Approach: The antenna is designed using a theoretical framework based on known equations as in literature. To construct and model the various antennas, the Computer Simulation Technology (CST) free student edition is employed. Findings/Result: By the proposed simulated models, the slit based patch antenna design 1 has achieved dual band characteristics with bands namely: at fr1 = 4.5 GHz (with return loss up to -30 dB) having bandwidth 1.5% and fr2 = 10.5 GHz (with return loss up to -26 dB) having bandwidth of 2.2%. Whereas, the design 2 has again dual resonances at lower and higher frequency bands with the reduced return loss up to -23 dB at fr1 = 4.5 GHz having bandwidth 1.5% and fr2 = 12.5 GHz with return loss up to -17 dB having bandwidth of 14%. Hence, the antenna design 2 has achieved the maximum bandwidth of 14% suitable for wireless applications, RADAR, Fixed-satellite services. Originality/Value: The design of slits cut on patch by varying inset feed width gap on flexible substrate for 5G frequency band is investigated. Paper Type: Original Research Contribution.

Abstract-This paper demonstrates simple, low cost and high gain microstrip array antennas with suitable feeding techniques and dielectric substrate for applications in GHz frequency range. The optimum design parameters of the antenna are selected to achieve the compact dimensions as well as the best possible characteristics such as high radiation efficiency, high gain, etc. In this paper different microstrip array antennas such as series feed, corporate feed and corporate-series feed are designed, simulated, analyzed and compared regarding to the antenna performances. The designed antennas are 4x1, 4x1, and 4x2 arrays. The optimum feeding system is decided based on the various antenna parameters that are simulated. The simulation has been performed by using SO ET version V12.56 simulator which is a commercially available antenna simulator. The designed antennas provide return losses in the range of -4.21dB to -25.456dB at frequencies around 10GHz by using Taconic TLY-5 dielectric substrate with permittivity, εr= 2.2 and height, h =1.588 mm. The gain of these simulated antennas is found about 15dB and side lobe label is maintained lower than main lobe. Since, the resonance frequency of these antennas is around 10GHz, these antennas are suitable for X-band applications such as satellite communication, radar, medical applications, and other wireless systems.
