Design of Rectangular Microstrip Patch Antenna 2-Elements Array for Dual Broadband Applications

The Long Term Evolution (LTE) and Wireless Local Area Network (WLAN) are different broadband communication systems. However, a microstrip antenna can use simultaneously for both. This paper discussed a rectangular patch microstrip antenna to support dual-band communication systems for mobile communication based on 4th generation LTE (1800 MHz) and WLAN (2400 MHz). The optimal configuration is obtained from the 2-elements array antenna. The 2-elements are connected by the T-junction multiple section corporate feed. The design is done with theoretical calculations, software simulation, and measurement of antenna fabrication. The results of the antenna measurements show that the bandwidth for VSWR below 2 is 1656–1909 MHz for the lower band and 2379–2597 MHz for the upper band. The half-power beamwidth for the lower and upper bands are 140° and 90°, respectively. While the gain for each band is 4.87 dB and 6.16 dB. The antenna is directional in the direction of vertical linear polarization. Thus, the antenna works well on devices that work on dual-system LTE 1800 MHz and WLAN 2400 MHz.
