Design of rectangle patch slot-u microstrip antenna electromagnetically coupled filing for broadband wireless access technology

Microstrip antenna design with millimeter-wave frequency has become a necessity for broadband devices, where wireless access networks are becoming increasingly important and the economic factor supports the use of the network so it is necessary to design an antenna that can be applied to Broadband Wireless Access (BWA) technology. Broadband technology requires the transfer of large data packets and fast data rate, to meet these needs, the antenna is designed Microstrip with U-slot rectangle patch with electromagnetically coupled feeding, the method used in this study is the research method, where for the design of the antenna microstrip through several stages. The design that has been done has resulted in the design of a u-slot rectangle patch microstrip antenna with electromagnetically coupled feeding and can be applied to broadband wireless access technology. Furthermore, the design results have a Substrate Antenna size of 27 mm × 21 mm. The results obtained that the antenna can work at a frequency of 2.368 GHz has a return loss value=-12.66 dB and 3.38 GHz has a return loss value of 15.22 dB, a VSWR value of 1.34, and has an antenna gain of 3.7 dB and has a frequency center at 2.3 GHz and 3.38 GHz and input impedance of 50 and vertical radiation polarization so that the antenna can be applied to Wireless Access networks.
