NOVEL HIGH GAIN EBS SHAPED MICROSTRIP PATCH ANTENNA DESIGN EMPLOYING FR4 SUBSTRATE FOR RADIO DETERMINATION, PASSIVE SENSORS, MARITIME RADAR, RADIOLOCATION (MILITARY)

This paper demonstrates analysis of Microstrip patch antenna design employing FR4 as substrate material, having thickness of 1.6 mm and dielectric constant ( ) of 4.3. The patch and ground are made up of Copper material with the thickness of 1mm. The design and simulation of antenna has been carried out using Computer Simulation Technology (CST) Microwave studio (2016). The proposed antenna design has been analyzed in terms of resonant frequency, return loss (S11), VSWR, gain (dB), directivity (dBi), Half Power Beamwidth (HPBW) and percentage bandwidth. It has been observed that the designed antenna is resonant at 13.74 GHz with an impedance of 51.06 Ω. The designed antenna has return loss (S11) magnitude of 62.68 dB at resonant frequency of 13.74 GHz. The antenna has gain of 6.8dB, directivity of 6.9 dBi. The proposed antenna can be used for Radio determination, Passive sensors ,Maritime radar ,Radiolocation (military), Active sensors, Altimeters, scatter meters, precipitation radars and Airborne Doppler navigation aids applications Broadcasting satellite (13.4GHz ¬¬- 14GHz).
