Summary
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.
