Hi, Kindly help me. I m designing a balance PIFA antenna in HFSS for GSM and UMTS (1900,2100). Q1 How to feed a balance PIFA antenna ? Q2 No current flows from my Patch,But gives a good Bandwidth and gain. Why no current flows ? Q3 How to match the PIFA antenna impedance without changing the position of (...)

What yo have shown is a basic bridge circuit, however I'm not sure why one of the legs is 50{ whilst the others are 100K. I suspect you also don't quite understand ordinary Op-Amps when used without feed back. Op-Amps are also known as "balance" amps in that they have increadibly high DC gain and thus will drive the output hard into the power
I'm designing a wide band microstrip tapered BALUN using Klopfenstein optimum taper. The usage of BALUN will be feeding an archimedean two-arm spiral so I need to match 50 ohms unbalanced coax feed to ~150 ohms balance antenna. My thought is to split the balance to Unbalance and (...)
Hi, The input offset voltage is amplified by the closed loop gain and appears at the output,the input offset current produces an output voltage equal to offset current multiplied by the feed back resistor. So in applications where the closed loop gain of the amplifier is not high, by choosing a relatively low feed back resistor, you can mini
HI HAVE A NICE DAY AND BE HAPPY NEGATIVE feed BACK Connecting the output of an op-amp to its inverting (-) input is called negative feedback. This term can be broadly applied to any dynamic system where the output signal is "fed back" to the input somehow so as to reach a point of equilibrium (balance). When the output of an op-amp (...)
