AI Thread Summary
Key equations for a phased antenna array involve calculating the individual element gain based on the number of elements and the array's aperture. The user is seeking specific equations to aid in building a phased array radio telescope for the UHF band. While resources like Microwaves 101 and Wikipedia provide some information, they lack the detailed equations needed. Recommendations include consulting the book "Antenna Theory: Analysis and Design" by Stutzman and Thiele for further insights. Access to comprehensive antenna literature is essential for accurate design and implementation.

What are the equations for a phased antenna array due to:

1. Individual element gain and the number of elements
2. Aperture of the array

I have been googling these for god knows how long and can't find the slightest hint, except the site Microwaves 101 (http://www.microwaves101.com/), which left out the f-ing equation I described in number one. I am building a phased array radio telescope for the UHF band (out of TV antennas) and am in dire need of these equations. Thanks, ls.

There's some math and other links at the wikipedia.org entry:

I haven't worked with arrays much, but my Antenna book by Stutzman and Thiele has a pretty good section in it. Do you have access to this book, or any other antenna books?
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
