A total of 150 students from a physical education college were selected to participate in this experimental teaching, and they were divided into the experimental group (EG) and the control group (CG). Based on the above purposes, the differences in the teaching methods and teaching objectives of the EG and the CG is that the former uses games as a key method in tennis teaching. All participants were asked to complete questionnaires, with the purpose of evaluating the learning motivation of tennis before and after sports game intervention. Additionally, the differentiated learning motivation and learning performance between EG and CG before and after experimental teaching was tested and evaluated. Results demonstrate that students in the EG have significantly increased their intrinsic motivation and introjected regulation, thereby showing better results than CG in key test items. In addition, the above result reveals the positive role of sports gamification in promoting the learning motivation and performance of college students.The aircraft avionics modernization process often requires optimization of the aircraft itself. Scale models of aircraft and their antennas are frequently used to solve this problem. Here we present interesting properties of the resonant antennas, which were discovered serendipitously during the measurement process of some microwave antennas' models as part of an aircraft modernization project. Aircraft microwave antennas are often designed as non-symmetric flat microwave antennas. Due to their thin, low and longitudinally elongated outer profile, they are also called tail antennas. An analysis of the resonant properties of non-symmetric antennas was performed in the band from 1 GHz to 4 GHz. The leng
