US6677909B2 - Dual band slot antenna with single feed line - Google Patents
A dual band slot antenna ( 1 ) for an electronic device includes an antenna body ( 10 ) with elongated first and second slots ( 11, 12 ) defined therein and a coaxial feeder cable ( 20 ) having a conductive inner core wire ( 21 ) and a conductive outer shield ( 22 ). The inner core wire is electrically connected to the antenna body at an outer side of the first slot 11 and the outer shield is electrically connected to the antenna body at an opposite, outer side of the second slot. The coaxial cable acts as a common feed line of the first and second slots.

The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see).

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.
