rl= returnLoss(antenna,frequency,z0)returns the return loss of an antenna. returnLoss(array,frequency)calculates the return loss of the individual array elements over the specified frequency at a reference impedance of 50 ohm and opens an interactive return loss plot. You can switch between the ...
of the RF transceiver; 3) an RF coupler coupled to an output of the RF mixer for transmitting the second test signal into the antenna and for receiving a reflection of the second test signal; and 4) a first signal monitor coupled to the RF coupler for measuring the reflection of the ...

Adams results found that without a ground plane the antenna has a return loss of less than -10dB at around 625 MHz and about 1.40 GHz. With a ground plane (placed on a metal surface) the antenna has good performance at around 535 MHz, 1.4 GHz and 2.4 GHz. This is not surprising as...
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 performance of the antenna is depends on the physical dimension of the antenna as well as location and shape of the DGS. Zealand IE3D is used for simulation and analysis of the proposed antenna. 展开 关键词: VSWR Microstrip Patch antenna Defected Ground Structure (DGS return loss band ...
