We design a small microstrip patch antenna with rectangular patches for use in mobile communication devices for mobiles. As can be seen from the results of the designed antenna, the small microstrip patch antenna was designed to have a center frequency of 1.91 GHz, which was successful. The ground plane dimensions of the patch antenna are designed to be 31mm x 40mm, and the patch dimensions are 22mm x 31mm. The designed antenna is sized enough to fit into a typical mobile communication device. Reduced posterior lobe radiation has been obtained, which is an additional advantage of the antenna when applied to mobile terminals because it minimizes the amount of electromagnetic energy radiated towards the user's handset. A gain of 1.87 dBi and a directivity of 5.56 dBi were obtained. The bandwidth obtained for this antenna is 23.28 MHz, and time division systems and global systems of mobile communications use 30 KHz channels, which is sufficient for personal mobile terminals. When mobile phones are connected through satellite networks to provide services to users, different networks must be able to operate the mobile terminal's antennas at separate frequencies. Work must be done to design a dichroic or trichromatic microstrip patch antenna that can operate at four or three frequencies and be used for many applications. |
