Novel Square Spiral Antennas for Broadband Applications [PDF]

open access: yesFrequenz, 2009
An investigation of novel square spiral antennas is presented. The antennas are designed by considering the special arrangements of spiral arms. The new designs perform much better in terms of the frequency independency of the fundamental antenna parameters, when compared with the well known and widely used Archimedean spiral antenna, which makes the ...

An assessment of interference cancellation applied to BWA [PDF]

open access: yes, 2007
It is a general principle that a communication system should be designed to avoid interference in the first place, either through network planning or with effective radio resource management and medium access control.
