4-2 Diode Matrix and Manufacturing Sequence 70 4-3 Diode Life Test Results Using Test Arrangement Shown in Figure 1-13. 74 5-1 Proposed design of Rectenna motivated by environmental protection and cost considerations. 76 5-2 Physical construction of two-plane rectenna. With the exception of covers (white teflon sleeves in photograge) this is the same five element foreplane that was electrically tested in Figure 5-12. Reflecting plane made from hardware cloth is representative of what could be used in SSPS rectenna. 76 5-3 Basic core structure design illustrating the joining of individual rectenna elements to each other to form a linear, easily-fabricated structure performing the functions of DC power bussing and microwave collection and rectification. 78 5-4 Proposed method of continuous fabrication of the core assembly of rectenna elements. 79 5-5 A mechanical mockup of the proposed design of Figure 5-1 showing how the metal envelope can be assembled to the core rectenna in a continuous-flow type of manufacturing assembly. The metal envelope is an early design and has been superceded 79 5-6 Artists1 concept of a moving rectenna factory. Materials brought in at one end of factory are basic ingredients to high speed automated manufacture and assembly of rectenna panels which flow continuously from other end of factory. Panels are placed on footings also placed in the ground by the moving factory. 81 5-7 Suggested assembly method in which staked-in ceramic pins provide the dual function of assembling the rectenna element and behaving as electrical capacitance in the low pass filter. 83 5-8 Schematic electrical drawing showing how the sections of parallel diodes are connected in series to build up to the desired voltage level at the output. 83 5-9 Fabricated Metal Shield Halves Which Will Support and Shield, both electrically and environmentally, the Rectenna-Element Core. 86
