Integrated Solar Panel Antennas for Small Satellites Prototype One Element Cavity Backed Slot Antenna . To verify the design, we fabricated a single cavity backed slot antenna. A simple ML feed as discussed in the previous section is used. The two substrates used are both Rogers high frequency laminates (RO 4003C) with the relative permittivity, thickness, and loss tangent of 3.5, 0.813 mm, 0.002 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

A Cavity-backed Coplanar Waveguide Slot Antenna Array James McKnight ABSTRACT In this thesis, a cavity-backed slot antenna array is designed for relatively wide instantaneous bandwidth, high gain and low sidelobes. The array consists of four, rectangular, slot elements, arranged side-by-side in a linear array and developed around 5GHz. WIDE BEAM TAPERED SLOT ANTENNA FOR WIDE ANGLE SCANNING PHASED ...
