摘要：In this paper, reduced ground rectangular microstrip patch antenna has been proposed. The antenna has been designed using substrate of FR4 material having dielectric constant of 4.4 with radiating patch and a ground plane. The ground plane has been partially reduced to improve the antenna performance. The antenna has a feed line which is connected to patch of width 9.22 mm. The feed line has to be of suitable width so as to match the antenna impedance with the port impedance (50 ohm).The feed line thickness is same as that of the patch thickness. The antenna performance has been analyzed in terms of various antenna parameters such as return loss (dB), impedance bandwidth (GHz), gain (dB), directivity (dBi), HPBW and VSWR. The proposed antenna has return loss (S 11 ) of -36.16 dB at resonant frequency of 4.39 GHz .The antenna has gain of 6.718 dB, directivity of 6.530 dBi and percentage bandwidth of 24.214 percent at resonant frequency of 4.39 GHz. The antenna has been designed and simulated using CST Microwave Studio (2010).The designed MPA is suitable to be used for Mobile Fixed Satellite (4.4 GHz – 4.99 GHz), Fixed Satellite (4.5 GHz – 4.8 GHz), Radio Astronomy(4.99 GHz – 5 GHz) and Aeronautical Radio Navigation(5 GHz – 5.15 GHz) applications. The antenna has a bandwidth of 1.063 GHz and VSWR is less than 2.
