Complementary structure of quadruple P-spiral split ring resonator (QPS-SRR) on modified Minkowski patch antenna design

In this work, a modified Minkowski patch antenna had been designed for 2.4 GHz of resonant frequency, f_r for wireless local area network (WLAN) application. The proposed complimentary structure of quadruple P-spiral split ring resonator (QPS-SRR) into the patch antenna had been increasing the gain performance. Other parameters that had been considered in this work are return loss, bandwidth, radiation pattern and directivity. This paper also discussed on the effect of single, double and triple sets of quadruple P-shape of the Minkowski patch antenna. This Minkowski patch antenna potentially can be operating the frequency range between 2.362 GHz to 2.427 GHz with a resonant frequency at 2.394 GHz and bandwidth of 65 MHz. The return loss of this Minkowski patch antenna is - 26.072 dB at frequency of 2.4 GHz while the gain is 2.555 dB at frequency of 2.4 GHz.
