Novel wideband high gain Right Hand Circular Polarized (RHCP) 2×4 Array Antenna at L-Band for data link applications
In this paper, a novel design for wideband high gain Right Hand Circular Polarized (RHCP) 2×4 array antenna at L-Band is presented for data link application. The proposed antenna used for long range highly maneuvering vehicles like missiles which needs high gain and RHCP to provide sufficient link margins. Orthogonal feeding is used for first patch and second patch is electromagnetically coupled to enhance impedance bandwidth. Sequential rotation technique is implemented to improve the Axial Ratio (AR) bandwidth. The antenna is simulated using commercially available software (CST microwave studio). The realized antenna reported 20.2% VSWR bandwidth, 14.64% AR bandwidth. The obtained gain is more than 14.5dBi, El & Az beamwidth of 44° and 20° over frequency band respectively.
