The paper presents a design of rectangular textile microstrip patch antenna suitable to be employed for radiolocation and exploration satellite applications. The textile material denim has been employed as dielectric substrate with relative permittivity (ε_r) of 1.6 having thickness of 0.7mm. The material employed for ground, feedline and patch is a perfect electric conductor (PEC). The microstrip feedline of appropriate width has been applied to feed the power and matching properly the antenna impedance of at 50 ohms with impedance of SMA port impedance for extreme power transfers from port to antenna with minimal reflection losses. The ground surface has been defected in order to advance the performance of the antenna in terms of bandwidth and reflection losses. The simulated results depict that the prototype textile antenna resonates at frequency of 11.192GHz corresponding reflection loss of –67.928dB with operational frequency range of 10.5GHz to 11.46GHz (960MHz impedance bandwidth). The antenna has gain and directivity of 7.587dB and 9.567dBi, respectively. The performance of antenna has been examined in terms of directivity (dBi), gain (dB), return loss (dB), half-power beam width (HPBW), Smith chart and VSWR. The manuscript clearly addressed the major problem of trade-off between gain and return loss in antenna systems, mainly textile antennas. The novelty and significance of the proposed research is enhancement in gain and return loss that is major issue of low dielectric textile materials in antenna designing. The proposed antenna system can be suitable for X-band applications in radio determination applications (10.5GHz-10.55GHz), fixed exploration satellite earth stations (10.6GHz-10.7GHz) applications and programme making and special events (PMSE) applications (10.5GHz-10.7GHz).
