You have an antenna with an input impedance of Z (140 -j35)2 at f 120 MHz. You would like to match this load to a 70Ω transmission line using a single stub tuner (vp-2.2x108 m/s). Using the Smith chart, determine the distance d away from the load and the length l of a short-circuited parallel stub to accomplish the matching goal at the design frequency. Estimate the reduction in radiated power if the operating frequency is changed to f 125...
A transmission line with characteristic impedance of 100 ? is connected to a 200+j400 ? load. Use Smith chart to calculate (i) standing wave ratio (ii) reflection coefficient (iii) lengths and locations of a short circuited shunt stub to match the load to the transmission line.

please follow instruction and solve every task in detail, thank you very much! A generator is connected to a transmission line system that is shown below. The system consists of two transmission lines, each with a characteristic impedance of 75 [2], connected to a load impedance of 75 [2]. These two lines are then fed by a single main feed line having a characteristic impedance 75 [2], which is fed by the generator (not shown). It is desired to have...
[50] You have a load with impedance (10+j10)? at the design frequency, f-100 MHz, that you want to match to a 50? transmission line (v,-3.108m/s). Using Smith charts, construct matching networks using the following elements: (a) a short-circuited parallel stub, (b) an open- circuited parallel stub, (c) a short-circuited series stub, (d) an open-circuited series stub, (e) a quarter-wave transformer. Assume ideal components. Specify the length of each transmission line in meters. ·

You are on an interview with Sungsam LTE and the interviewer shows you their new 2300 MHz cell phone transceiver and antenna printed circuit board (PCB) shown below. "Between the RF source and antenna is a matching network of small circuit elements (i.e. inductor, capacitor or resistor) - the antenna feedline has a characteristic impedance Zo of 50 Ohms", she exclaims. She goes on to request you show her using her Smith Chart how you would 'match' the PCB trance...
I need help to solve this questions about Generator Governor Droop and Transmission Line. A complete solutions with answers would be great. Thank you Generation Question 1 to 5 relate to the following grid connected generator.
