Abstract

This paper proposes a novel and compact conformal fork-shaped microstrip patch antenna operating at 10.2 GHz for X-band wireless communications. It features a fork shaped unique radiating structure optimized for impedance matching, bandwidth enhancement, and compactness. Parametric studies confirmed optimal performance at feed width 3.5 mm and thickness 0.4 mm. An operating band from 9.31 to 11.88 GHz for S₁₁ <= -10 dB with a bandwidth of 2.57 GHz is attained. It exhibits a peak gain of 5.6 dB at 10.2 GHz with radiation efficiency 88.29%. To validate its suitability for flexible and modern wireless applications, conformal models are developed, and their performance is analyzed for metrics like operating band, radiation patterns, peak gain, and radiation efficiency. It is prototyped on a Rogers RT Duroid 5880 substrate, and experimental validation demonstrates strong correlation between simulated and measured characteristics.
