Design of multi band triangular microstrip patch antenna with triangular split ring resonator for S band, C band and X band applications

With the rapid advancement in multi-functional communication devices, devices capable of operating for more than one frequency bands emerged. Such applications demand for multiband antennas. Wide band antennas are capable of resonating over larger frequency bands, but it limits the impedance bandwidth and gain. So, the solution of this could be compact multi band antennas. A quad band Triangular Microstrip antenna designed for IEEE 802.16e Wi-MAX, IEEE 802.11a WLAN, C band downlink communication and x band radar applications is suggested in this work. The proposed antenna has triangular patch with triangular split ring resonator. The conservativeness and data transfer capacity are the preferred possessions of the suggested antenna. The proposed antenna yields better return and gain by resonating in 3.5 GHz, 4.1 GHz, 5.6 GHz and 9.7 GHz.

Automated summary

This paper presents a quad band Triangular Microstrip antenna for multi-functional communication devices, with a compact design and high performance, achieving good return and gain in multiple frequency bands.
