A Four-Element Sequentially Rotated Ceramic-based Antenna Array with Circular Polarization
In this work, a four-element Al<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>O<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> ceramic-based antenna array is designed which is fed by a sequentially rotated (SR) feedline showing circular polarization (CP) behavior, operating in the C-band. The SR feed is implemented to maximize the power delivered to each and every element while reducing its input impedance. The radiators generate HEM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11δ</inf> modes. The overall dimensions of the antenna array are optimized to be 92x92x1.6 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> which obtained -10dB bandwidth of 1.11 GHz (5.33 GHz - 6.44 GHz) and dual CP band (< 3dB Axial ratio (AR)) from 5.57 GHz to 5.62 GHz and 6.30 GHz to 6.32 GHz. The proposed antenna array is suitable for C-band microwave applications.
