Develop Model for an Antenna with Dual Band Microstrip Patches

The wavelength, low scale, medium-frequency, and high-frequency are typically defined as an antenna. This article implemented a dual-band patch antenna for bands 7 and 3 for suitable LTE. Physically, the scale of the patch antennas may be minimized. The FR4 substrates 4.3, 1.6 mm represent Ɛr and h respectively are used for developing the new model of an antenna with the dual-band microstrip. The antenna of width (108.7 mm), length (77.8 mm), and height (1.6 mm) are built for the ground plane. The other parameters calculate to achieve the frequencies 1.8 GHz and 2.6 GHz purposed of design. The result shows the return loss of S-Parameter achieved -20 at 1.8 GHz and -20.5dB at 2.6 GHz. The bandwidth at 1.8 GHz is 55 MHz while at 2.6 GHz is 89 MHz depending on the S-Parameter. The Fairfield of the maximum directivity is 7.200 dBi with a total efficiency of -2.899 dB at a frequency of 1.8 GHz while 2.6 GHz obtain 6.868 dBi and -3.718 dB for a maximum directivity and total efficiency, respectively. The simulation and design were done by CST microwave studio.
