MICROSTRIP LINE CST MICROWAVE STUDIO PDF PATCH

For the designing of rectangular microstrip antenna, the following relationships are used to calculate the dimensions of rectangular microstrip patch antenna. Antenna is designed for a resonating frequency of 5.5 GHz and 6.4 GHz and is analyzed using CST Microwave Studio software. In this design we have used a defected ground structure which gives the good resonance. In this work, microstrip line (50 ohm) feed has been used. Microstrip patch antenna can be fed by different methods like microstrip line feed, coaxial probe feed, aperture coupling, electromagnetic coupling and coplanar waveguide (CPW). The main concept behind the designed structure is to implement DGS structure to reduce the antenna size and to enhance the bandwidth of the antenna. Edges along the width are called radiating edges and that along the length are called non radiating edges. The ground has been reduced from all the sides with a pie (  ) at the centre of the ground. The power divider can be used in the input at 9.8 GHz frequency band, over 800 MHz. The proposed power divider has good agreement with the theoretical CST microwave studio simulated data and measured data. The existence of cross polarization components of the field inside the waveguide structures if exists, have also been considered to obtain an accurate result. In the present analysis global basis function has been used. Numerical data have been compared with the data obtained with laboratory measurement, and CST Microwave Studio simulation. Codes have been written for analyzing the frequency response characteristic of the structure, mentioned above. Finally attempt has been made to improve the frequency response characteristic of the above mentioned waveguide circuit using a sorting post to diversify the power equally in all the ports. The antenna is numerically simulated using CST Microwave Studio 2014 and experimentally measured near to a semi-solid head-equivalent phantom, particularly S11 and radiation pattern on xy- and yz-plane at 5.8 GHz.Ībstract-In this paper a method of moment based analysis of an H-plane 1:3power divider has been presented using Multi Cavity Modeling Technique (MCMT) in transmitting mode. The proposed antenna is a printed dipole-like fed by a coplanar waveguide because it provides high frequency response. In this paper, an UWB antenna is proposed as a transceiver of microwave imaging on brain tumors, which it operates in UWB range (i.e. Microwave imaging is considered as a suitably matched modality to those requirements. Hence, it is desirable to develop a new brain tumor imaging system that is affordable, easy to operate (portable), non-ionization (safe radiation) and use a non-invasive technique. However, it costs still relatively high particularly in developing countries with high population like Indonesia.

MRI, PET, or CT is widely used modalities for brain tumor scanning, which it can provide accurate and high resolution image. This paper mentions that Brain tumor is one of degenerative diseases that have been concerned by doctors and researcher to be investigated.

Experimental verification of the model resulted to 1.18% error of the actual versus predicted moisture extracted.Ī UWB Antenna for Microwave Brain Imaging is proposed by Adhitya Satria et. The study successfully used fractional factorial design (FFD) with center points to model the interaction effects on MVD parameters on moisture extracted and color of rice bran. Subsequently, drying experiments were then carried out.

A PLC-based control box with HMI display was developed to constantly monitor the drying kinetics of rice bran. mixing the product during the drying process). To achieve uniform product heating, a rotary drive assembly was incorporated into the system (i.e. Using CST Microwave Studio simulation software, it was seen that the best design for a 30-L MV chamber operating at 2.45 GHz is a cylindrical chamber with a radius of 202 mm, length of 400 mm, and with 2 perpendicular feeders located near the ends of the chamber. The study initially conducted a methodical analysis of the microwave chamber and its auxiliary attachments. Abstract-This study presents an optimized design of a PLC- based microwave vacuum dryer which was used to conduct preliminary investigation of the effects of drying parameters on the drying kinetics of rice bran.
