There is a considerable year by year increase in the number of women suffering from breast cancer. Early diagnosis is important to ensure the survival of patients. This study presents the development of a novel, wearable and flexible multiple input multiple output (MIMO) 2×4 antenna design, which operates at a frequency of 5.5-7 GHz for time-domain breast tumor detection.The antennas are all located in the cup of a bra, which is divided into four quadrants; each quadrant has two antennas for tumor detection. The parameters S11 and S21 for each antenna were measured in the frequency domain. The measured results of S11 and S21 indicate that the antennas worked well both with and without a breast phantom model at the assigned frequency. For antenna five, located in the third quadrant (the quadrant with the tumors), the signal response of the antenna on the breast phantom model had a higher amplitude than that without the breast phantom model. The results demonstrate that the antennas worked well for the detection of the tumors.

This article examines the various investments made by Tiongkok in a number of countries, one of which is Indonesia in an effort to expand its economic hegemony in the international world. The Beijing consensus is the foundation of the People's Republic of Tiongkok in strengthening its economic position by providing foreign investment to developing countries, both in Asia and Africa. Although adopting communism as the principle of domestic politics, the pattern of expansion of investment carried out by Tiongkok under Xi Jinping actually leads to capitalism and neoliberalism as stated in the points contained in the Beijing Consensus. Purpose: This article seeks to explore the process of Tiongkok investment abroad. Design/Methodology/Approach: This article uses a literature review as the research method. Findings: This article finds that despite using the ideology of communism for its domestic hegemony, Tiongkok applies a capitalist economic style in its foreign investment and foreign trade. Originality/Value: The novelty of this article is the author's attempt to explain the differences between Tiongkok's trading style and the logic of its domestic power.
