The design of a microstrip antenna array for a UHF space telemetry link

An analytical and numerical analysis of the radiation from a slotted conducting cylinder with axial columns

“…The resulting predicted effect of the fence was much less than that suggested by the earlier pattern measurements on the cylindrical PDF model with columns (21).…”

“…Â computer program was developed to obtain the radiation pattern of a slotted cylinder antenna without columns (10,25,26). To simulate the entire pattern with columns present, an analytical expression and a program were developed to find the near-fields at the cylinder surface, so that their interaction with columns could be determined (6,10,21).…”

“…The original experimental design and study of the PDP (21) showed that the radiation pattern of the PDP, with support columns (as is Figure 1-1) and with either one or eight microstrip antenna panels, was quite sensitive to the position of the panels relative to the columns. A major question which the present work was designed to answer was whether this effect was due to scattering from the columns in the presence of a standing wave set up around the cylinder by the antenna panel apertures, or whether it was caused by some other effect, e.g., near-field perturbation by the antenna panels themselves on the outside of the cylinder.…”

Effect of electroacoustic waves on radiation properties of microstrip matched coaxial termination

“…For the past few years, printed circuit antennas have proven to be effective radiators because they are low-profile, extremely rugged and normally quite inexpensive to fabricate (Derneryd 1976;Carver & Mink 1981). They have found applications for communication in space (Post & Stephenson 1981).…”
