Design of Linear Array Triangular Patch Antenna for Mobile Communication

Mobile communication is growing rapidly, hence it requires devices including an antenna which is small, light, and compact. Researches on microstrip antennas which emphasize on its performance and miniaturization have been carried out extensively. The selection of dielectric material could sometimes achieve the desired antenna performance for some application. Therefore, the dielectric material usage is still one of important factors in the design and implementation of microstrip antennas. This paper proposes a 1×2 linear array triangular patch antenna design for mobile communication application. The array antenna which is designed on FR4 epoxy dielectric substrate with the thickness of 1.6 mm and relative permittivity 4.3 is configured with several feeding line systems. Some antenna parameters such as operating frequency, reflection coefficient, bandwidth, and gain are used to evaluate the performance of array antenna. From the characterization, the proposed array antenna has operating frequency of 2.364 GHz, reflection coefficient of −35.753 dB, working bandwidth of 83 MHz, and gain of 3.375 dB.
