Revolutionary claims for novel antenna
design
A novel type of antenna is claimed to liberate wireless developers from the problems and restrictions associated with conventional technology.
Antenova has developed a novel type of antenna that liberates wireless developers from the problems and restrictions associated with conventional technology The new freedom made possible by the introduction amounts to a revolutionary force for wireless terminal and infrastructure designers

Antennas coexist in slimline smartphone
The T818 is a triband Edge Newplus Linux core smartphone that combines all the functionality of a mobile phone, a PDA and a multimedia device.
The technology results from over three years of pioneering R and D that has transformed the effect of high dielectric antennas (HDAs) from scientific curiosity into completely characterised technology - backed by a design methodology and computer-aided tools.
HDAs not only improve the size and performance of antennas - they enable completely new product design possibilities.
These include the first practical approach to incorporating 'antenna diversity' into products - greatly enhancing signal strengths and with it data communications performance.

Directionality is another possibility, which may be used to foster coexistence of multiple protocols on equipment, to add spatial multiplexing of bandwidth to increase the capacity of wireless networks (with easy mechanisms to support solid-state beam steering).
For handset and terminal developers, HDA technology offers much smaller size, much higher efficiency, immunity to detuning, and directionality.
These parameters can be employed to deliver many new degrees of performance.
Multiple antennas to be integrated inside the product to support diversity processing for example; this would be extremely difficult to achieve with conventional antennas because they would need to be at least a half-wavelength apart to avoid coupling (around 7cm at 3G frequencies).
Antennas can be made to transmit in certain directions only - reducing power consumption.
And they have almost no 'near field', further reducing local radiation and avoiding the detuning effects which can deteriorate performance in the field, and/or necessitate design changes during development.
For developers creating basestations and other wireless infrastructure such as wireless LAN nodes, HDA technology offers much smaller size, directionality, and immunity to detuning for easy coexistence of multiple antennas and protocols.
Among the possibilities opened up by these features are easy construction of multi-operator, multiband basestations with substantial reductions in visual blight.
And, an enabling technology for the creation of new-generation products such as 'pico' basestations suitable for deployment within street furniture, or compact multi-protocol units for LAN applications.
The control of directionality is so great that basestation coverage can be very precisely targeted, supporting the introduction of spatial multiplexing as a means of multiplying network capacity.
Spectrum can easily be divided in six arc segments of 60s for example, or even more if required.
Alongside the practical knowhow on HDA technology, Antenova has constructed a toolsuite including its own simulator, which allows high performance antennas to be created rapidly to suit the specific needs of product developers.
The company's own anechoic chambers and other test facilities then allow working samples to be provided rapidly to end users for product prototyping and test.
The design can be provided for clients to manufacture themselves, or produced by Antenova in conjunction with its volume-manufacturing partners.
Antenova is currently working with developer partners engaged in almost every segment of the wireless industry.
