| Research Abstract |
In this study, a new method for combining the spectral and spatial filtering functions into antenna system was investigated. This method offers downsizing in filter configuration. The new feed-network design is proposed, where the feed network decouples the array antenna with arbitrary number of the antenna elements and prevents the transmitted signal from flowing into the receiving antennas. Experimental results indicated that the proposed feed network works expectedly and is effective in decoupling the multiple antennas.
