Environmental Sensitivity of Large Stealth Longwave Antenna Systems

This article presents an analysis of measurements collected during a six-month-long experimental deployment of a surface-placed horizontal magnetic loop antenna. The changes in the measured parameters of the loop are investigated in relation to the surrounding environment’s composition, temperature and water content. Basic functions describing these changes are formulated. The results are confronted with outcomes from similar experiments from previous years and different locations, showing good compliance. The developed functions and antenna system can be used for environmental monitoring of soil composition and humidity over large areas and volumes, helpful in, for example, flood awareness.

Average Fade Duration

Exact and closed form expressions for the average level crossing rate (LCR) and average fade duration (AFD) of the output signal envelope of selection diversity system are derived, assuming each branch is subject to independent but nonidentical composite fading in distributed antenna systems (DAS). Numerical results validate the derived expressions. It shows that DAS promise significant diversity gains over collocated multiple antenna system.

Small Loop

Pada pengujian kompatibilitas elektromagnetik khususnya pada pengukuran near field, pengukuran medan magnet sangat diperlukan. Salah satu alat pengukuran yang digunakan adalah magnetic loop probe. Penelitian ini dilakukan untuk membandingkan loop probe pada jumlah sisi geometrinya, dan belum ada referensi yang membahas tentang topik ini. Magnetic loop probe didesain dalam tujuh bentuk geometri yaitu bentuk segi 3 (ada dua model), segi 4, segi 6, segi 8, segi 10, dan segi tak hingga (lingkaran) dimana parameter keliling geometrinya sama. Magnetic loop probe didesain dengan menggunakan perhitungan sebagai small loop antenna Karateristik kelima desain probe dianalisis dengan mengukur S21 sebagai sensitivitas menggunakan Vector Network Analyzer. Karateristik bentuk probe maupun gain dan sensitivitasnya dibahas dalam makalah ini.
