Microstrip Antenna Design for In-Cabin 4G (LTE) and WiFi Communication Systems

The essence of this study is the broadband microstrip that can be integrated into devices, whether it is 4G (LTE) mobile network or WiFi wireless internet connection, at the same time, since today's mobile phones are not ready for 5G infrastructure, during airplane journeys, which have become an indispensable means of transportation in daily life, includes antenna design details and simulation results with High Frequency Structural Simulator (HFSS) program. It is aimed to design a microstrip patch antenna that can communicate with both 4G (LTE) and 2.4GHz WiFi wireless communication bands at the same time, by integrating it into mobile personal devices such as mobile phone, tablet, laptop, etc. The related microstrip patch antenna design was designed with the microstrip feeding method and the material selection was in favor of the FR-4 dielectric material. In order to increase the bandwidth, measurement differences were made on the ground floor of the design. According to the microstrip patch antenna design and simulation results made with the HFSS program; antenna center frequency is 2.57 GHz and S₁₁ value is measured as -24.18 dB. The bandwidth of the system is at 250 MHz. In addition, the antenna gain value is simulated as 3.08 dBm. Due to the large size of the designed antenna gain and broadband, it has been seen that it can be used efficiently in both 4G (LTE) and 2.4 GHz WiFi (between 9-14 channels) wireless communication systems in today's existing mobile phones.
