Anybody here has gone through "Design of non planar microstrip antennas and transmission lines" by KL Wong? especially chapter 2 and 4?? or implemented it or trying it?
:!: :idea: :?:
Assume a Tx-Rx system at frequency f where two antennas (with gain G1 and G2) are there with zero reflection, 100% efficiency and no sidelobes. The distance between the two is say d. Tx antenna generats a very sharp pencil beam and Rx antenna apertue is large enough to receive all...
I am going to make a microwave camera. just like optical one. no tracing or tracking. Microwave pinhole camera. Who can help me to select:
1. A box
2. Pin Hole
3. Photographic plate
4. Focusing lense
First of all I want to know what will be my output picture??
Suppose we are designing a Circularly Polarized (CP) array wich is consists of four sub arrays. Now which array should give best CP performance in terms of CP bandwidth, Axial ratio at center frequency and CP HPBW?
1. Sequential rotation of 4 sequentially rotated sub array
2. Array of 4...
Is it available??

Which type of notch filter (15 MHz BW) is best suitable for GSM band. Which simulator shoul I prefer. I am thinking to start with Parfil and check with Sonnet. Is it ok?
I need to reduce the insertion loss. I want to choose stripline with air subtrate and thick lines and shorted...
A very nice collection.
Must see the pictures:
But I could not run that 3D. :( Try and check

vswr 50r 75r
Earlier 75 Ohm systems were used. Most probably it was a Russian standerd. Not sure though. But now 50 Ohm has become standard almost in all applications. My question is which system is better?
I feel 75 Ohm is better because easily connected with dipole or yagi antennas. Suitable...
chamfered microstrip bend
How to get best chamfering in microstrip lines (in terms of chamfering factor or angle) for:
1. 45, 90 and 135 degree bends
2. single step and double step
What are the merits and de-merits of these methods?
How to calculate the exact path length in...
