A low-frequency annular-slot antenna - NIST Page A Low-Frequency Annular-Slot Antenna James R. W ait The radiation characteristics of an annular slot cut in an ideally conducting ground plane are discussed. The voltage impressed between the concentric edges is assumed to be constant around the slot. The annular slot is backed by a hemispherical cavity which has A STUDY OF A COMPACT MICROSTRIP-FED UWB ANTENNA WITH AN ... A STUDY OF A COMPACT MICROSTRIP-FED UWB ANTENNA WITH AN OPEN T-SLOT X.-F. Zhu and D.-L. Su School of Electronic and Information Engineering Beihang University Beijing, China Abstract|In this paper, a compact and simple microstrip-fed slot antenna is proposed for ultra-wideband (UWB) applications, which BROADBAND CIRCULARLY POLARIZED DIELECTRIC RESONATOR ... the work in [18], a broadband CP cylindrical DRA with annular slot excitation is investigated here. Figure 1 shows the geometry of the proposed antenna. The cylindrical DR has a radius of a = 5mm, a height of d = 12mm and a relative permittivity "d = 10:2. The DR is positioned on top of the substrate. An annular slot and an L-shaped microstrip ...
