Abstract

This project discussed about the performance of designed Microstrip Patch antenna and Microstrip Patch antenna with Split Ring Resonator (SRR) for a Short Range Device (SRD). Both antenna has been designed at 900MHz frequency which satisfied with short range standard in Malaysia. The main things in this project is to determine the maximum distance can be covered by both antennas in transmit and receive data. Besides that, the performance of parameter that has been studied were return loss, gain and radiation pattern. FR4 with thickness 16 mm has been used as the substrate and copper with thickness 0.035 has been used as patch material. The design was developed and simulated by using CST Studio Suite software. From the simulation results, for Microstrip Patch antenna, the return loss is -28.22dB, gain 2.32 dB, radiation pattern Omni-directional pattern and bandwidth 9.08 MHz. For Microstrip Patch antenna with SRR, the return loss is -15.38 dB, gain 0.98, radiation pattern Omni-directional pattern and bandwidth 9.64 MHz. Both antennas have been measured after the fabrication process. For Microstrip Patch antenna, the return loss is -16.168 dB at 920.5 MHz, gain 1.234 dB, radiation pattern Omni-directional pattern and bandwidth 10 MHz. while for Microstrip Patch antenna with SRR, the return loss is -24.5 dB at 909.5 MHz, gain 0.352 dB, radiation pattern Omni-directional pattern and bandwidth 14 MHz. After the measurement process, both antennas have been tested by doing the field test at UTeM Sport Complex. From the field test, the Microstrip Patch antenna has the maximum distance 0.11 km in transmit and receive data, while Microstrip Patch antenna with SRR the maximum distance can be covered in receive and transmit data was 0.16 km.
