Conference Proceeding: Analysis and design of a satellite-borne wide-beam conical quadrifilar helical antenna
[show abstract] [hide abstract]
ABSTRACT: In this paper, a novel conical quadrifilar helical antenna for GPS application is presented. The antenna behaves wide beamwidth and circular polarization. Numerical simulations show that the pitch angle and the length of radiating arms are main factors which influence the beamwidth of this kind of antenna. The model antenna designed working at center frequency of 1.5968GHz characterizes: (1) about 180 degrees of 3dB beamwidth which satisfies the requirement of the hemisphere radiation, (2) about 0. 35 GHz of 3dB axial ratio bandwidth, and (3) VSWR under 1.5 : 1 covering 1.5859~1.6075 GHz. Details of the antenna design along with simulated results are presented and discussed.Signals Systems and Electronics (ISSSE), 2010 International Symposium on; 10/2010 -
Conference Proceeding: Design of L-circularly polarized microstrip antenna array at Ka band
[show abstract] [hide abstract]
ABSTRACT: In this paper, a L-circularly polarized aperture-coupled feeding microstrip patch antenna array with a high gain and a good axial ratio is presented. It's suitable for operation in portable satellite communications stations. The microstrip line feeding of circular microstrip patch antenna is applied and the coupling aperture is the cross-shaped aperture. The proposed antenna array covers 29.4-31.0 GHz at the Ka band. Details of the antenna array design along with simulated results are presented and discussed.Microwave and Millimeter Wave Technology (ICMMT), 2010 International Conference on; 06/2010
