摘要

This paper discuses the design of wideband microstrip antenna which is for mobile communication especially for 4G/LTE application. The 4G/LTE applications use frequency bands 850 MHz, 900 MHz, 1800 MHz, and 2300 MHz. Therefore, an alternative to support all these bands in one antenna is to design a wideband antenna. To achieve the antenna specification that has the characteristics of wideband, one of the methods that can be used is to add parasitic elements in a rectangular microstrip patch antenna. The antenna design uses FR4 substrate with a dielectric constant of 4.6 and substrate thickness 1.6mm. Ground plane, feed line, patch and parasitic elements using copper material with a thickness of 0.035mm. By using this technique, frequency band is obtained at 793.66 MHz up to 2501.34 MHz and have a bandwidth of 1707.64MHz. Approaching omnidirectional radiation pattern is obtained at the frequency of 850-900 MHz and significant changes in the 1800-2300 MHz frequency. Gain increases with increasing operating frequency. The highest gain in the range of 1800-2000 MHz is 4.47 dB. With the characteristics of this antenna, the result of the antenna design can be used for 4G/LTE application.
