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.
LTCC or LCP, A comparison using cavity backed slot antennas with pin curtains at 60 GHz | IEEE Conference Publication | IEEE Xplore
LTCC and LCP technologies are compared for 60 GHz antenna design in terms of antenna polarization purity and efficiency. Cavity backed slot (CBS) antennas with pin curtain walls are chosen as the antenna element and modelled using the FDTD technique. The performances of the antennas are analysed while changing the substrate used. Substrate losses and conductor losses are calculated and total radiated powers in lossy and lossless cases are studied to reach the final efficiency figures. The CBS antenna on LCP is found to be more efficient and have better radiation properties.
