COMPACT MULTIBAND INSET FEED MICROSTRIP PATCH ANTENNA

摘要

The Micro Strip Patch Antenna has a low profile, small size, light weight easy to integrate with active elements, and low cost. The main contribution of the project is optimization and achieve of high gain, high directivity, very low return loss and easy to adapt in MMICs (Monolithic Microwave Integrated Circuits) technology. The inset feed microstrip patch antenna for future applications using FR-4(Flame Retardant) substrate. The proposed antenna is capable to maintain its high performance over wireless operating system. The proposed antenna is designed at the height of 0.8mm from the ground plane, and a dielectric constant is 4.4. The antenna parameters such as Bandwidth, Return loss, VSWR (Voltage Standing Wave Ratio), Gain and Directivity are investigated in the proposed antenna. As the fabrication process involved in manufacturing the inset feed microstrip antennas is simple to the complete production process and it is easy and very cheap. Due to low cost advantage, mass production of the MSA (Micro Strip Antenna) is easily achievable using modern advanced printing circuit technologies. The simulated S-parameter value is -11.52dB, -15.93dB, - 18.77dB, -8.95dB, -17.92dB, -24.35dB, -28.63dB, -13.74dB, -18.33dB, -14.16dB,and-11.01dB.
