Novel Designs of End-fire Dipole Array Antennas

In this report, a novel type of dipole array antennas is discussed. A narrow-band dipole array antenna and a broad-band dipole array antenna are simulated and measured as two examples. Metallic strips and broadside I-shaped resonators are also placed for improving the bandwidth and gain. More than the bandwidth and directivity, the broad-band antenna also has undistorted radiation pattern, high front-back ratio and small size. These properties make it suitable for point-to-point wireless communication, imaging applications and wireless power transmission.
