The data model for direction of arrival (DOA) estimation is revisited and studied with more attention to the practical implementation of the antenna arrays and verified through measurement results. A complete data model for a single-channel direction finding system that includes, for the first time, the effects of the switching mechanism among antennas is presented. In order to combat coupling among...
A general design of a high-gain wideband single-layer radial line slot array antenna is discussed for V-band applications with a 6GHz gain bandwidth, to be compared with that of planar Fabry-Perot cavity antennas that is in general narrower. The antenna is based on a simple laminated single layer and a planar integrated feeding structure is proposed as a preliminary choice to excite such design.
Circular Polarized (CP) antennas are useful in wireless communication since the CP waves will not be affected as they travel in different media. Moreover, the CP antennas compared to Linear Polarized (LP) antennas are less sensitive to the orientation angle between the transmitter and receiver. Unlicensed 7-GHz bandwidth at center frequency of 60 GHz is amenable for high data rate wireless communications...
