A system includes a radio frequency (RF) connector terminal that is configured to connect to an antenna, and a RF transmitter that transmits RF power to the RF connector terminal. The system further includes a power measurement unit that measures, as a first power measurement, first RF power...
returnLoss(array,frequency,z0,elementnumber)calculates and plots the scan return loss of a specified antenna element in an array. rl= returnLoss(array,frequency,z0,elementnumber)returns the scan return loss of a specified antenna element in an array. ...
Using this configuration, we obtained 83.88% as patch antenna return loss bandwidth at operating frequency range of 3 to 7 GHz. The EBG structure is designed on FR4 substrate which has a dielectric constant of 4.4 and thickness of 1.6mm. The proposed design has reduced the return loss from ...
Return Loss in dB What It Means VSWR Number 0 dB 100% reflection, no power into the antenna, all reflected back Infinite 1 dB 80% reflection, 20% power into the antenna 17 2 dB 63% reflection, 37% power into the antenna 9 3 dB ...
As [W.sub.p2] = 1.0 mm, the bandwidth of return loss remains less than 10 dB for the entire band from 4.6 to 13.8 GHz, but the impedance matching of the radiating patch with input impedance deteriorates at higher frequencies. Design of CPW-Fed Antenna with Defected Substrate for Wideband...
The patch is made concave in both horizontal and vertical sides. Applying the proposed structure to a microstrip array antenna having two elements, the effects of patch concavity on the mutual coupling and return loss are simulated and studied. To obtain a concave rectangular patch array antenna ...
In this paper a modified inset-feed microstrip antenna is proposed to increase band width and return loss. The operating frequency of the antenna is 2.4 GHz ISM band. To enhance the performance of the antenna one DGS has been introduced under the patch area that is on the other side of su...
A network analyzer is capable of measuring the antenna return loss in a live cellular network. The network analyzer receives and analyzes the base station transmitted signal to determine which transmit frequencies are active. Based on information relating to the correlation between the transmit frequency...
