“…In general, the Vivaldi antenna has an end-fire radiation pattern. However recently, we have demonstrated that by placing a ground plane and a parasitic antenna layer below and above the driven antenna layer respectively, the direction of main beam can be scanned in the elevation plane [2]. This arrangement is attractive for local multipoint distribution service (LMDS) in residential areas were it is necessary for the antenna to conform to the roof surface for aesthetics while the beam is required to point towards the sky for good line-of-sight propagation.…”

The paper presents first, an efficient measurement technique to characterize the input impedance of a Vivaldi antenna, second, a simple technique to impedance match a Vivaldi antenna to a 50 f2 feed line and lastly, a desktop arrangement to determine the directional gain of a Vivaldi antenna. The characterization is done using a microwave wafer probe station, a ground-signal microwave probe, impedance standard substrate and an automatic network analyzer. The Vivaldi antenna with a matching transformer has a VSWR close to unity and a gain of about 10 dB over the frequency band of 27.5 to 28.35 GHz which is allocated for local multipoint distribution service (LMDS).
