Multi-feed compared with single-feed end-fire antenna

A new method of designing an end-fire plate antenna structure is presented in this paper. To improve directivity and gain, different number of short end-fire antennas located along axis direction instead of single long end-fire plate antenna. Compare with traditional single-feed plate antenna, multi-feed structure has excellent performances. From the simulations and practical measurement, the conclusion can be made that this structure is very advance to develop high-directivity end-fire antenna array.
