A new low cost antenna for high-precision applications in Global Navigation Satellite Systems (GNSS) is described. The antenna has been designed to operate for all existing satellite navigation frequencies in L-band including GPS, GLONASS, Galileo and Compass (1164–1300MHz and 1559–1610MHz).

IEEE Antennas and Propagation Society Symposium, 2004., 2004
Enhancing the operational capability of current sensors and radar systems to detect targets at long ranges and map the terrain in all kinds of weather is a well-accepted measure. Multi-target tracking would require multi-beam, multi-band scanning phased array antennas. Therefore, in order to meet the current challenges, current sensor systems and radar

Sampling of multi-band signals
2000Abstract This paper is about sequences (tn) of real numbers with the property that knowl edge of a signal s at these points, that is, (s(tn) tells us everything about the signal. In order that this problem makes sense it is necessary to assume that the spectrum of the signal is constrained in some way.
