摘要： Methods, systems, and apparatuses for manufacturing light weight microstrip element antennas incorporating a skeleton dielectric spacer instead of a regular solid body dielectric spacer is described. The microstrip element antenna comprises a radiator, a dielectric layer which is in the form of a skeleton rib-caged structure and a ground plane layer. Due to the skeleton rib-caged structure of the dielectric spacer, design flexibility in terms of a non-uniform variation of the effective dielectric constant across various dimensions of the dielectric layer is obtained. Additional advantages of such a dielectric spacer include a wider choice of materials from which the antenna can be made, overall light weight and low production time and machine cost due to lower cooling time of the dielectric. Further, an antenna with a skeleton dielectric spacer further has a better drying characteristics in an event of a water ingress during or post-production.

摘要： A distributed comb tapped multiband antenna structure includes a PIFA-like antenna radiator having tap structures, and a counterpoise to the antenna radiator, wherein the tap structures include shunt connections to the counterpoise. A second antenna radiator is collinear and opposing the antenna radiator while sharing the counterpoise in common with the antenna radiator, such that the antenna structure is configured as a balanced dipole. The antenna structure can be contained internally within a single device housing and can operate over multiple frequency bands. The antenna provides high performance over a considerable bandwidth within each of the multiple frequency bands of operation, even where the frequency bands are not harmonically related.

摘要： A method and device enables improving a signal to noise ratio (SNR) of a backscatter signal received from a radio frequency identification (RFID) tag. The method includes generating a continuous wave (CW) carrier signal at the reader device (step 505). An amplitude modulation (AM) noise component of the CW carrier signal is then detected (step 510). The AM noise component is inverted to an inverted noise signal (step 515), and the inverted noise signal is summed with the CW carrier signal to provide an AM noise cancelled carrier signal (step 520). The AM noise cancelled carrier signal is then transmitted from an antenna of the reader device (step 525), and the backscatter signal is received at the reader device in response to transmission of the AM noise cancelled carrier signal (step 530).
