Miniaturized MPA with Asymmetric Z-Shaped CSRR Loading

The work in the paper demonstrates a rectangular microstrip patch antenna with a Z-shaped CSRR loading in the ground plane. A Z-shaped CSRR created in the ground plane, shown a 63.3% miniaturization in the radiating patch size compared to conventional rectangular patch antenna, resonating at 6.5GHz frequency in C-band. The simulation results find a significant increase in the fractional bandwidth (5.54%, with the centre frequency of 6.5GHz). Furthermore, the antenna has simulated gain of 2.83dB and return loss of -26.33dB at 6.5GHz. The electrical size of proposed antenna is 0.325λo × 0.260λo × 0.034λo (i.e., 15mm×12mm×1.6mm). The proposed antenna may find application in satellite communication systems in C-band and Wireless local area network (WLAN).
