Low gain antenna
WebA gain-enhanced antenna consisting of a bandpass frequency selective surface (FSS) and a patch antenna is initially proposed in this communication. By utilizing the reflection … WebVSWR is determined from the voltage measured along a transmission line leading to an antenna. VSWR is the ratio of the peak amplitude of a standing wave to the minimum amplitude of a standing wave, as seen in the following Figure: Figure 1. Voltage Measured Along a Transmission Line. In industry, VSWR is sometimes pronounced "viz-wer".

We inserted two high-impedance surface (HIS) structures between the radiating elements and added two electromagnetic band gap (EBG) layers above the antenna. The antenna gain increases from 7.56 dB to 14.8 dB.

They had a maximum bandwidth of 1,200 bits per second compared to the 134,000 bit/s expected from the HGA. As the spacecraft moved further from Earth, it also necessitated the use of the DSN's 70 meters (230 ft) dishes, to the detriment of other users, who had …
