JI, 2.400-2.485 GHz ISM Band Embedded
Antenna (2002, PDF)
The JI from Ethertronics represents a new category of small form factor,
embedded antenna for ISM band applications. The unique design represents a
breakthrough in delivering high efficiency, isolation and selectivity.
The JI allows product designers to easily create highly integrated
antenna systems. The superior isolation enables components to be placed in
close proximity to the antenna without affecting performance thereby
minimizing the product integration effort. A self-contained ground plane
enables the antenna be mounted next to or on top of existing components or
shields. This feature makes it an attractive choice for modifying existing
product designs with minimal impact. The unique design shapes the
near-field pattern in the nearby surrounding, maximizing antenna
performance.
The high selectivity of J Series antennas enables system designers to
reduce costs by removing filters. High selectivity gives better rejection
of out-band signals. This extends network range, enhances mobility and
improves voice and data quality indoors, in noisy environments and in
fringe network coverage areas.
The JI antenna is ideally suited for wireless handheld and mobile devices,
where performance, size and system costs are critical. The design and
compact size are very manufacturable and are suited for high volume
applications. Several semi-standard package profiles (mechanical
dimensions) are available or can be modified to suit individual OEM
requirements.
JI applications: Bluetooth, DECT, HomeRF, WiFi, WLAN, etc.
