This paper explains about a 3×3 Rectangular microstrip patch antenna Arrays using HFSS 140. The motivation for using radar technology is that it is unaffected by poor weather conditions or low visibility unlike visual based surveillance systems.
Finally we analyzed the 1×4 corporate feed linear microstrip patch array antenna that has been designed with dielectric constants of 𝛆𝐫 22 with fixed substrate height of h15748mm substrate RT Duroid 5880. This example project illustrates the simulation of an array of microstrip patch antennas. Patch Antenna Array in use for Wi-Fi communications Refer to Appendix A for the single patch antenna design procedure.

Also the performance results are In 2015 International Conference on Computer presented. From monitoring space down to ocean surveillance with many more applications in between. Conclusions Antenna array concept is used to improve the better gain of different antennas by nullify the side lobes.
Quality factor Q of microstrip antennas is a very high. Ishra esign and Analysis of ic Fig 2. Products Include Antennas Radar Reflectors Luneberg lens and Testing.
An example of this type of array is. Geometry of proposed 3 element array antenna. Quality factor can be reduced by increasing the dielectric substrate.
FR-4 substrate material is selected for designing array antenna whose dielectric constant is 44 The substrates dielectric constant is an essential design parameter. The EM structure 16_Element_Array is for calculation of the port properties and antenna pattern of the 4 by 4 patch array again using AXIEM. – Microstrip patch antenna 19 GHz single patch antenna 1×2 linear array antenna 1×4 linear.
In this paper the proposed antenna presents the design of novel circular patch microstrip antenna array operating at 24GHzOne way of attaining antenna gain is. The performances of the rectangular 41 and 22 patch antenna arrays. But due to increasing thickness unwanted power loss occurs by the surface wave.
Three different configurations of 24 GHz Frequency-Modulated Continuous Wave FMCW patch antenna arrays were designed manufactured and tested with an existing radar. Design of 8×1 patch array antenna using ROGERS-3006 outputs better result as far as gain of the antenna is concerned in comparison with FR-4 in X-band application at precise frequency of 10 GHz. Return loss The above figure shows the return loss of 1×4 antenna arrayThe return loss of -225dB is obtained at 35 GHzThe.
Patch Antenna Array In order to increase main beam gain reduce side lobe radiation and increase directivity the patch antenna design was expanded to a four element array. This article proposes a design and implementation of array Microstrip Patch antenna of configuration 2 2 at an operating frequency of 35 GHz. The technology existed before but was mainly developed in.
Modern computer-aided design even allows the arrays to follow curves con-tours of aircraft or vehicle bodies. Experimental results for a 28 array antenna with a superstrate and a 48 array antenna without a superstrate. Designing of patch array antenna is initiated by determining the.
