is paper presents a circularly polarized microstrip antenna used for 2.4 GHz WLAN applications. The designed antenna consists of a circular patch fabricated on FR-4 substrate with a V-shaped slot carved on its surface and a circular metal plate (reflector). The antenna substrate is stacked above the reflector by a small distance. The antenna size a...

WO2013165809A1 - Antenna structures having slot-based parasitic elements - Google Patents
Electronic devices may include radio-frequency transceiver circuitry and antenna structures. The antenna structures may include antenna resonating elements and antenna ground plane structures. An electronic device may have antennas formed from the antenna resonating elements and an antenna ground plane. The antenna ground plane may have slot structures. The slot structures may be configured to form a slot-based parasitic antenna element to minimize coupling between the antennas in a device. The slot-based parasitic antenna element may be located between the antennas in a device. The slots structures from which a parasitic antenna element is formed may include open slots and closed slots. Slots may have one or more arms and one or more bends. Slots may be formed in internal housing members, traces on dielectric carriers, and other conductive structures.
