A Novel Coaxial Continuous Transverse Stub Antenna Array for High Frequency Satellite Applications
Authors: ,
Abstract: The need for antenna with multiband capability is miniaturization of design and improvement of bandwidth. Planar antennas suffer narrow bandwidth problem. This paper focuses on the implementation of multiband high gain antenna array for wireless satellite and aircraft applications with improved bandwidth. The proposed antenna structure consists of three pair of radial coaxial stubs in a zigzag manner. The stub pair consists of one large stub and another small one to radiate for multiple frequency bands. This cascaded structure offers high directivity and gain with minimum return loss. This proposed antenna structure covers the frequency range of 10 GHz to 26 GHz. The fabricated antenna of the proposed structure radiated for four frequency bands with minimum return loss. These frequencies are well suited to satellite, space craft and military applications.
