The modern portable communication devices demand compact antenna with superior performance and reduced size and weight. The design and development of such antennas for broadband applications is a challenge for the researchers. In this paper, a microstrip patch antenna with h BN nanoceramic‐based substrate for S‐band application has been proposed and analyzed its performance experimentally. The proposed antenna has been fabricated using powder metallurgy and etching process. The performance of the fabricated antenna has been analyzed in terms of its characteristics such as return loss, gain, and radiation efficiency. Return loss of the proposed antenna is obtained as −43 dB at resonance frequency. Proposed antenna using h‐BN nanoceramic substrate achieves peak gain of 8 dB and acceptable radiation efficiency in S‐band.
