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.

Bandwidth Enhancement of Slotted Rectangular Wideband Microstrip Antenna for the Application of WLAN/WiMAX | Wireless Personal Communications
In this research paper, compact and slotted patch antenna geometry of size (30.8 × 37.2 mm) has been designed and investigated at frequency 3.30 GHz. The proposed antenna covers 2.08–3.99 GHz frequency band suitable for S-band (2–4 GHz) wireless communication. The proposed geometry of antenna design consist two notches and one vertical slot. The bandwidth of antenna is enhanced gradually by cutting notches and slot in antenna patch. The variation made in antenna structure enhanced the antenna bandwidth and antenna resonating at frequency 3.29 GHz near design frequency. The proposed antenna exhibits impedance bandwidth of 62.9% (1910 MHz) resonating at 3.29 GHz with peak gain of 4.7 dB at frequency 3.89 GHz. Resonating frequency band of antenna is applicable for WLAN/WiMAX. Microstrip line fed antenna geometry is fabricated and simulated through IE3D simulation tool.
(PDF) 38 GHz Antennas on Micromachined Silicon Substrates
A new configuration of a double folded double slot CPW feed micromachined antenna array was realized on a 1.5 µm thin three-layer dielectric membrane fabricated on a silicon substrate. The antenna was designed for an operating frequency of 38 GHz,
A Brief Guide to Slotted Array Antennas - Rantec Microwave Systems
The fundamental principle behind a slot antenna is that it functions as the dual of a dipole antenna. In a dipole antenna, current flows through two rods or wires, creating an electric field that radiates electromagnetic waves.
