In this article, a miniaturized square slot-loaded patch antenna with a rectangular bulged slot and a complementary π-shaped slot carved on the ground plane is proposed. The tri-band of resonant frequencies was obtained by exciting a rectangular bulged slot and a complementary π-shaped slot with a microstrip-fed slot-loaded patch antenna. FR-4 dielectric substrate of 50 mm x 50 mm x 1.56 mm has been used to fabricate the antenna. The resonant frequencies of 8.4, 9.4, and 11.9 GHz were acquired for X-band applications, including wireless networks, radar systems, and satellite communications. Impedance matching and wide bandwidth are achieved with the implementation of the defected ground structure (DGS) technique. The experimental validation of antenna characteristics, including reflection coefficient, gain, bandwidth, and radiation efficiency, demonstrates strong concordance with simulated results.
