REQUIREMENTS

1. Summarize a recent IEEE paper regarding the use of non-Foster circuits (such as negative capacitors) 
   
• Where non-Foster circuits enable small antennas that are suitable for mobile communication at low frequency (under 1 GHz)
  
• Where non-Foster circuits enable small antennas having wide bandwidth to support broadband communication
  
• Papers are assigned by instructor as follows:  (some papers have negative inductors and capacitors, but only simulate the negative capacitance as noted below)
• Papers
  
1. Use -9.6 pF from article and use Fig. 7 ideal NIC bandwidth compared to passive bandwidth and use Fig. 1 picture of antenna in "UHF Electrically Small Box Cage Loop Antenna With an Embedded Non-Foster Load," by   Justin Church ;  Jia-Chi Samuel Chieh  ;  Lu Xu ;  John D. Rockway ;  Diana Arceo
   
2. Use -2.2 pF from article and use  Fig. 3(c) bandwidth of NFC 6.8V compared to NFC 0.0 V and use Fig. 2(a) picture of antenna in "Non-Foster Matched Antennas for High-Power Applications," by Minu M. Jacob  ;  Daniel F. Sievenpiper.
3. Use -1.0 pF from article and use Fig. 2(b) bandwidth non-Foster compared to conventional matched and use Fig. 1(a) picture of antenna in "Non-foster broadband matching networks for electrically-small antennas," by Nikolay Ivanov, Bair Buyantuev, Viacheslav Turgaliev, Dmitry Kholodnyak
4. Use -0.5 pF from article and use Fig. 1(a) conventional match bandwidth compared to Fig. 1(c) non-Foster bandwidth and use the picture of the loop anntenna inset to Fig. 1(a) in "Non-foster circuits for small broadband antennas," by Stavros Koulouridis and  John L. Volakis
• Paper Assignments:
• Paper 1: assigned to project groups 1, 5,   9,  13,  17
  
• Paper 2: assigned to project groups 2, 6,  10,  14, 18
  
• Paper 3: assigned to project groups 3, 7,  11,  15, 19
  
• Paper 4: assigned to project groups 4, 8,  12.  16,  20
  
2. Simulate the non-Foster circuit (some papers have negative inductors and capacitors, but only simulate the negative capacitance as noted for your paper)
• Your negative capacitor design MUST be a digital non-Foster negative capacitor as discussed in class
  
• Read the report template before doing anything
  
• Simulate the negative capacitor using MaathCad project as was done previously
  
• Do the simulation using MaathCad
• In Maathcad the negative capacitor sample rate must be 10 times the highest frequency of your antenna
  
• In your report, compare the Maathcad computed impedance simulation result to the impedance of an ideal negative capacitor (or negative inductor) at the both ends of the frequency band.  Ideal impedance of a capacitor would be 1/(jwC).
  
3. Write a 2-page IEEE-format report using the template e4124finalProjTemplate_cryp.zip  (paswword is instructor last name)
   
• Use the report template
  
• Provide all required data as exemplified in the report template
• Table I with Bandwidth (passive compensated and non-Foster compensated),  physical size of antenna,  half-wave dipole size for purposes of comparison to a "normal antenna" (calculate this as equal to half of a wavelength in free space, where wavelength=speed-of-light/frequency-in-Hz), and non-Foster capacitance (and non-Foster inductance, if applicable)
  
• Table II with impedance at lower and upper ends of non-Foster bandwidth for the simulated negative capacitor and ideal negative capacitor,  In each row of the table compare the Maathcad computed impedance (real and imaginary parts) simulation result to the purely imaginary ideal impedance 1/(jwC) of an ideal negative capacitor
• Fig. 1 is a picture of the antenna from your assigned paper
  
• Fig. 2 is a picture (or pair of pictures, depending on the paper you were assigned) of the passively-compensated and non-Foster compensated bandwidths from your assigned paper
• Fig. 3 is a simple block diagram to go with the equation describing your theory, your negative capacitor design MUST be a digital non-Foster negative capacitor as discussed in class
• Fig. 4 is a snapshot of your MaathCad formula for H(z) and  circuit clearly showing your component values
• Fig. 5 is your simulation result for the assigned negative capacitance (see each paper above, it differs for each paper), making sure that you plot ths over the same frequency range as the non-Foster antenna plot of your antenna, and rescale it (usually from -500 to +1000 ohms) so that the real and imaginary parts of the plot are both visible.
  
• YOU MUST ADD CAPTIONS AND FIGURE NUMBERS TO ALL FIGURES!!
• DO NOT FORGET TO EMAIL a pdf copy of the report to the instructor during the class period when the report is turned in
  
• IN NO CASE may code or files or data or pictures be exchanged between student groups, there is to be NO COPYING of reports
  
4. Prepare powerpoint slides
• Maximum: 10 slides
  
• REQUIRED slides as a minimum
• Slide with presentation title and optional group member names (groups may remove names from video if you prefer to remain anonymous)
  
• Slide containing Table I along with the Fig. 1 picture of the antenna from your assigned paper
• Slide containing the Fig. 2  picture (or pair of pictures, depending on the paper assigned) of the passively-compensated and non-Foster compensated bandwidths from your assigned paper
• Slide containing the Fig. 3 simple block diagram to go with the equation describing your theory PLUS the theory equations
  
• Slide containing the Fig. 4 MaathCad frmulas  of your circuit clearly showing your component values
• Slide containing Table II along with the Fig. 5 is your simulation result for the assigned negative capacitance 
  
• DO NOT FORGET TO EMAIL a pdf copy of the powerpoint to instructor (as a backup in case of video problems)
• IN NO CASE may code or files or data or pictures be exchanged between student groups, there is to be NO COPYING of powerpoint slides
  
5. Prepare presentation video
• Record video  5 minute maximum video,
• Upload to canvas
• IN NO CASE may code or files or data or pictures be exchanged between student groups, there is to be NO COPYING of videos
6. Participate in peer review of final presentation videos during the final exam session
