Design and fabrication of compact triangular multiband microstrip patch antenna for C- and X-band applications

摘要

Modern portable communication devices require a compact antenna with superior performance and lower weight and size. The design and development of such a compact size antenna are a significant challenge for researchers. This proposed work compact slot-based triangular patch antenna to work at the multiple resonance frequencies from 5 to 10 GHz using FR4 substrate is presented. The proposed antenna is simulated using High-Frequency Structural Simulator (HFSS 2020R1). Simulated and fabricated antenna test results show that the proposed antenna can be suitably employed for the portable wireless transceivers in C and X bands. It has been inferred from the fabricated and measured results that the proposed slot-based triangular patch antenna achieves the peak gain of 8 dBi and has excellent impedance matching properties such that return loss S11 is less than -10 dB and VSWR value is significantly closer to 1 at all the resonance frequencies.
