A design of radial line slot array antennas using the specification of panel antennas | PDF
This paper presents the design, simulation, and testing of radial line slot array (RLSA) antennas using the specifications of market-available 16 dBi panel antennas for Wi-Fi applications. The developed RLSA antennas demonstrate superior performance with a 0.25 dBi higher gain and a bandwidth that is 570 MHz wider than the panel antennas. Testing confirms that the RLSA antennas are effective for Wi-Fi communication, validating their potential as an alternative to conventional antennas. - Download as a PDF or view online for free

A Survey on Emerging WiMAX Antenna Technologies and Slotted Microstrip Patch Antenna’s for WiMAX Applications | PDF | Internet | Computing
This document discusses various antenna technologies for WiMAX applications, including SISO, SIMO, MISO, MIMO and AAS modes. It also reviews slotted microstrip patch antennas, specifically double C-slot and C-slot designs. Key findings include: 1) Slotted microstrip patch antennas can improve gain, return loss and VSWR over conventional patch antennas for WiMAX. 2) A double C-slot design achieved a return loss of -31.6 dB and gain of 6.4 dBi, outperforming a C-slot antenna. 3) Slotted designs provide a 37% reduction in antenna size compared to conventional square patches. - Download as a PDF or view online for free

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.
