The design of an antenna based on Substrate Integrated Waveguide (SIW) has been The antenna shows high gain of 11.8dBi and is suitable for application in satellite and radar communication system. The array has been simulated and optimized using full-wave EM CAD Tool CST Microwave Studio. The array configuration has been extensively analyzed with parametric studies of important parameters within the design and possible effects have been presented for proper selection of design dimensions. In order to generate in-phase electric field distributions on every radiating slot, alternating offsets in the slots is used to generate in-phase electric field distributions on every radiating slot. Basic design includes Y-junction power divider and symmetrical linearly polarized slot array antenna elements.
The article describes the proposed antenna with all its necessary parameters. more Design and analysis of a Single layer high gain Substrate Integrated Waveguide (SIW) Antenna Array has been presented in this article. Measurements show an improvement of more than 25dB in the port isolation when DGS integrated microstrip antenna.ĭesign and analysis of a Single layer high gain Substrate Integrated Waveguide (SIW) Antenna Arra. An experiment of investigating isolation between the ports has been performed by employing with and without DGS. DGS-integrated microstrip line offers image impedance of 150Ω and it is controlled by DGS geometry.
#CST MICROWAVE STUDIO TUTORIAL REALIZED GAIN PATCH#
The patch is excited through microstrip feed line of 75Ω line impedance. The microstrip line at two different ports integrated with DGS restricts the high order harmonics signals coming from transmitter or receiver. Port isolation of the antenna, while feeding the 3.0 GHz port, port-2 and filtering out the 2.45 GHz signal from port-1. A spiral-shaped DGS-integrated microstrip line enhances the port isolation of the antenna, while feeding the 2.45 GHz port, port-1 to the antenna and filtering out 3.0 GHz receiving signal from port-2.Similarly a rectangular shaped DGS-integrated microstrip line enhances the Integrated with defected ground structure (DGS). more This paper presents a high port isolation dualįrequency orthogonally polarized rectangular patch antenna This paper presents a high port isolation dualįrequency orthogonally polarized rectangular patch.
