Abstract
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 is a major challenge for the researchers. In this proposed work compact slot based triangular patch antenna to work at the multiple resonance frequencies from 5 GHz to 10 GHz using FR4 substrate is presented. Proposed antenna is simulated using High Frequency Structural Simulator (HFSS 2020R1). Simulated and fabricated antenna test results shows that proposed antenna can be suitably employed for the portable wireless transceivers in C and X band. Proposed slot based triangular patch antenna achieves the peak gain of 8 dBi and has the good impedance matching properties such that return loss S11is less than -10 dB and VSWR value is very closer to 1 at all the resonance frequencies.
