Abstract

Objectives: To design an antenna for WiMax application radiating at a frequency of 2.5GHz. Methods/Statistical Analysis: In the recent years with the rising development in digital systems, the demand for antennas which is of low profile, light weight has improved. This paper details about the design of patch antenna which is square in shape. Findings: The preferred operating frequency for the radiating patch is 2.5 GHz .The suggested patch can be utilized in the WIMAX. In order to achieve the effective radiation the slot is created on the square patch. The above defined radiating element is simulated with the use of ADS software. The Simulated design offers return loss of -13 DB at the designed frequency. Applications/Improvements: The radiating element is intended to use for WiMax.

Abstract

Objectives: An innovative image superpixel segmentation approach run on the test image to acquire the probabilities of every pixel and performs grouping in light of shading similarities and spatial nearness of the pixels in histopathologic images. LRW algorithm using self-circles has the benefits of portioning the weak limits and confounded surface areas extremely fit. Method of analysis: This technique starts with instating the seed locations and tracks the LRW algorithm on the test image to acquire the probabilities of every pixel. At that point, the limits of starting superpixels is acquired by the probabilities what’s more, the drive time. Findings: At the point when the outcomes are assessed, it has been watched that the superpixel strategy has a positive commitment to both the segmentation achievement and the running time. The execution of superpixel is enhanced using moving the focus places of super pixels then separating the huge superpixels into little with the proposed improvement procedure. The exploratory outcomes have shown that our technique accomplishes preferable execution over past superpixel approaches. Application/Improvements: To detect the distance objects as a test image, and through this method, we can analyze and provide an optimal solution where time is constraint.

Abstract

Objectives: To design an antenna for cognitive radio application. Methods/Statistical Analysis: With the advancements in the technology the demand for the radiating elements which are less in weight and size with increased efficiency has increased. T Shaped patch is designed to operate in different frequencies. Findings: The paper explains the outline of T molded fix. The T formed fix receiving wire is contrived for the subjective radio application. The working recurrence is 3.45 GHZ. The receiving wire is outlined and simulation by utilizing ADS software. The Simulated outline offers return loss of - 16 DB at the planned recurrence. Applications/Improvements: As the users increase, the spectrum is now becoming a scarce resource and demands for the efficient utilization. Thus, the cognitive radio came into the field and necessitates the antenna to be flexible for multi operating environment and compact.
