US4547779A - Annular slot antenna - Google Patents A microstrip annular antenna structure is formed by four quarter-wavelength microstrip radiator patches arranged in a quadrant formation and having outwardly directed adjacent radiating apertures which together provide a composite annular radiating slot extending about 360° of azimuth. Polarization Reconfigurable Eccentric Annular Ring Slot ... Abstract: A microstrip-fed reconfigurable eccentric annular ring slot (EARS) antenna with switchable polarization is proposed. To generate orthogonal circular polarization (CP) radiations, two identical perturbation slots (PSs) are loaded below the eccentric ring-shaped slot. Miniaturization and Bandwidth Enhancement of a CPW-Fed ... 2. CPW-FED ANNULAR SLOT ANTENNA DESIGN In this work, a conventional annular slotted structure is employed as the reference antenna. Geometry of the annular slot antenna with a CPW-feed line is shown in Figure 1(a). In general, a microstrip slot antenna is very popular due to its compact, low-profile and easy to integrate with monolithic microwave A Compact Annular Ring Microstrip Antenna for WSN Applications

Circular ... Microstrip-Fed Dual-Frequency Annular-Slot Antenna Loaded ... Microstrip-fed dual-frequency annular-slot antenna loaded by split-ring-slot X.L. Bao M.J. Ammann Centre for Telecommunications Value-chain Research, School of Electronic and Communications Engineering, Dublin Institute of Technology, Kevin Street, Dublin 8, Ireland E-mail: max.ammann@dit.ie What is the difference between slot antenna and patch ... Slot antennas are easier to make and modify, though patch antennas can be nearly as cheaply made using printed circuit board production lines. Slot antennas can send much more powerful signals. You can build a slot antenna into a structure and put it somewhere others may not know it is. The Pros and Cons of Slot Antennas


How is Annular Slot Antenna abbreviated? - TheFreeDictionary This study presents an annular slot antenna design and implication with the functional microstrip circuit module by using a single probe feed to reconfigure the circular polarized states. Jiang, "Design of CPW-FED dual-band circularly-polarized annular slot antenna with two perturbation strips," Progress In Electromagnetics Research C, Vol. Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.
