Abstract

Wireless Fidelity (Wi-Fi) is the modern telecommunication technology nowadays being so widely used and developed at operating frequency of 2.4 GHz, that needs microstrip antenna as best suited supporting means for transmitting and receiving data signals as well at its wave transceiver subsystem.  The proposed antenna design were consists of four elements rectangular patch antenna with peripheral slits technique arranged in a linear array of 2x2 operating at the frequency of 2.4 GHz until 2.5 GHz. In addition to that, the feeding technique used in this research is microstrip fed line. The simulation from this research resulted in reducing the size of related antenna dimension up to 17% compared to that of four elements array without peripheral slits. It is also apparent that the bandwidth of the proposed antenna is 320 MHz (2.253 GHz–2.573 GHz) which is equivalent to bandwidth increase percentage of 13.07%, The simulation results in the center of frequency 2.448 GHz obtained return loss of -26.14 dB with a VSWR of 1.104. The measurement results obtained bandwidth of the proposed antenna is 150 MHz (2.424 GHz–2.574 GHz) which is equivalent to 12% increase of bandwidth percentage. The results of measurements process at the center of frequency 2.448 GHz obtained value of return loss of -16.88 dB with  VSWR of 1.304.

Abstract

This research proposes a dual-feed microstrip antenna using a peripheral slit for mobile communication systems. Miniaturization and reduction of the dual feed microstrip antenna’s size have been investigated and explained in this paper. The proposed antenna dimensions are reduced using three pairs of slits while the resonant frequency is 1800 MHz. Based on simulation and optimization results, the proposed antenna dimensions can be reduced by 94.81% compared to conventional multiple feed channel microstrip antennas. These results indicate that the peripheral slits technique has succeeded in reducing the proposed antenna dimensions without changing its frequency. We get a reflection coefficient of -31.65 dB, VSWR of 1,053 at a frequency of 1.95 GHz, and bandwidth of 206 MHz with a frequency range from the measurement process of 1.85 GHz–2.06 GHz with a bandwidth of 210 MHz. Impedance obtained from the proposed antenna is 47.72 ± j0.67 Ω at frequency 1.95 GHz.

Abstract

This paper proposed a new design of circular polarization E shaped patch microstrip antenna fed by proximity coupling for Wireless Fidelity applications at operating frequency of 2.4 GHz. To generate circular polarization in the proposed antenna, the next steps is making three slits on the patch antenna and with this embedded three slits produces antenna E shaped. Besides that, the proximity coupling fed line is used to increase the bandwidth of the proposed antenna. In this research the patch E shaped was put on the first substrate layer while the proximity coupling feeder was put on the second substrate layer. The substrate material used in this research is one of the two layers FR 4 Epoxy with relative dielectric constant ( r) of  4.4  and thickness (h) of 1.6 mm. The circular polarization can be achieved by adjusting the width and length of the E shaped antenna. The simulation of this research gave some important antenna parameters such as axial ratio value of 2.58 dB, return loss of -19.98 dB, VSWR of 1.223 and bandwidth of 151.3 MHz. Finally, its measurement results gave also some related comparative data such as return loss of -22.12 dB, VSWR of 1.16, bandwidth of 153.2 MHz, and Half Power Beamwidth of 580.
