Measurement Engineering to Design a Truncated Ground Plane Compact Circular Ring Monopole Patch Antenna for Ultra Wideband Applications

In this paper, using in-depth simulations and measurements, a simple and compact design is engineered for making a circular ring microstrip patch antenna radiating element which is suitable for different ultra wide band(UWB) applications. This design approach is different because it has not utilized the usual method of using a set of electromagnetic equations and calculations to make the radiating antenna. Measurements and simulations were performed on Microwave CST. Using this measurement engineering approach, novelty of proposed antenna structure is obtained by making the required changes in the ground plane. The measurements showed that truncating the ground plane by a square shape structure of 2.5mm by 2.5mm size at the feed point was practically significant to provide an impedance bandwidth (\({S}_{11}cript>\)) ranging from 2.75 GHz to 32.035 GHz with a VSWR which is less than 2. For this entire bandwidth the directivity has shown a variation from 0.8 dBi to 7.9 dBi. The compact size (33mm x28mm x1.57mm), low design complexity, very high bandwidth, good directivity and satisfying VSWR has made this antenna unique among all previously presented UWB antennas.

Multidisciplinary and international virtual collaboration on the “Shared Garden” between the Universities of Bordeaux and León

This case study describes two iterations of a cross-disciplinary Virtual Exchange (VE) project developed between the Universities of Bordeaux (France) and León (Spain), involving students of Applied Physics and Measurement Engineering (APME), and Electrical Engineering. The students worked together on designing a real garden in Bordeaux within ecological and sustainable parameters. This Project-Based Learning (PBL) activity helped them develop both their content knowledge and their competences in English, teamwork, time management, and self-evaluation.

The Analysis of Cognitive and Psychomotor Domains in Basic Competence in the Subject of Land Measurement Engineering in Curriculum Vocational Schools - Area of Expertise Construction and Property

This study considers the cognitive and psychomotor domains on basic competency, specifically those related to land measurement techniques taught in vocational schools. Qualitative research methods are combined with the content analysis approach. The results showed that there were 20 basic competencies which students had to learn for land measurement. As a cognitive domain, there are 10 competencies with details of 7 basic competencies referring to the C3 level (applying), 1 basic competency at the C4 level (analyzing), and 2 basic competencies at the C5 level (evaluating). In the psychomotor domain, there are 7 basic competencies at level P2 (manipulation), 2 basic competencies at P3 (precision) and 1 basic competency at level P4 (articulation). It can be concluded that there is a balance in the ability of the cognitive and psychomotor domains on the basic competencies of subjects in land measurement techniques in Curriculum vocational school area of expertise Construction and Property.
