摘要：In this paper, the substrate slotted microstrip patch antenna for X-band fixed satellite, mobile satellite and space research applications has been proposed. This proposed design has been fabricated over FR4 substrate having dielectric constant ε r = 4.4 and thickness of 1.57 mm. The designed antenna is a wideband antenna with percentage bandwidth of 17.11% (7.18GHZ-8.51GHz) and with resonating frequency of 7.77GHz. The antenna has been fed by microstrip feedline via impedance transformer to match the input impedance of the antenna with the 50. impedance of SMA connector. The proposed antenna has been analyzed in terms of return loss(S 11 ), Voltage Standing Wave Ratio (VSWR), gain, directivity, smith chart and Half Power Beam Width(HPBW)The designed antenna has return loss (S 11 ) of -68.05dB, gain of 4.904dB and directivity of 4.6 dBi. The proposed antenna can be suitably employed for X-band applications . fixed earth exploration satellite, space research, defense systems, radio determination and UWB(Ultra-Wide Band), weather satellites and satellite payload telemetry applications. The proposed antenna has been designed and simulated in CST Microwave Studio 2014.
