US3810183A - Dual slot antenna device - Google Patents A dual slot antenna assembly is disclosed herein and generally includes a pair of concentrically positioned and radially spaced cylindrical conductors defining a pair of circumferential slots which are longitudinally spaced one-half wavelength apart at the anticipated operating frequency of the antenna device. An electrical signal feed assembly ... WIDE BEAM TAPERED SLOT ANTENNA FOR WIDE ANGLE SCANNING ... exponential taper results in a so-called linearly tapered slot antenna (LTSA) for which the taper slope is constant and given by s 0 = ( y 2 ¡ y 1 ) = ( x 2 ¡ x 1 ).
A vertically stacked array antenna structure is described. The structure comprises a radiating layer, a passive layer disposed under said radiating layer, an active layer disposed under said passive layer, and an interface assembly.
60GHz Slot-Array Antenna Design Based on Gap Waveguide Cavity ... Index Terms— Double-layer structure, cavity-backed slot antenna, waveguide slot-array, corporate feed network. I. INTRODUCTION Waveguide slot array antennas are expected to provide high aperture efficiency and also high gain at mm-wave frequencies due to the lower losses in the distribution networks [1-2]. A COMPACT DUAL-CIRCULARLY POLARIZED CAVITY-BACKED RING- SLOT ... on top of the center conductor of a ring-slot antenna. Two cavity-backed ring-slot antennas are presented with unidirectional radiation properties. The first is a linearly polarized CPW-fed ring-slot antenna. A T-shaped CPW feed was used to capacitively excite the ring-slot structure. The bottom of the cavity is formed by an AMC Design Of A Wideband Dual-polarized Cavity Backed Slot Antenna
