In this paper, fully controlled interference cancellation module (ICM) for an 18 GHz 2 × 2 line-of-sight (LoS) multiple input, multiple output (MIMO) system is presented. A 2 × 2 LoS MIMO hardware prototype with a 110 MHz channel bandwidth and data rate of 250 Mbps per path (total of 500 Mbps) was fabricated in the 18 GHz band. In the 16-QAM digital modulation test, the experimental results show that...
In this paper, an 18 GHz 2 × 2 line-of-sight (LoS) multiple input, multiple output (MIMO) system for fixed wireless access is presented. The amplitude variation by the antenna beam pattern are calculated in a LoS environment for 2 × 2 MIMO system development. In addition, the theoretical SIR from these variations is extracted and verified through H/W test.
Design of stacked circular patch antenna having the omni-directional in the azimuth plane has been proposed for very short range 60 GHz WPAN application. The proposed antenna uses LTCC technology, which makes easier to integrate with a transceiver chip.
