| Abstract: | A light-weight low-cost tightly coupled dipole array (TCDA) antenna is presented for wireless power transfer. A simple low-cost H-plane scanning booster (HSB) layer is first introduced to improve the scanning ability in H-plane. Therefore, a consistent E- and H-plane scanning performance is achieved for the designed unit cell. In addition, a new 1to4 differential feed network using power dividers and exponentially tapered baluns is designed and utilized to excite the unit cell. Finally, a 5×13 finite array antenna prototype was designed, fabricated, and measured for wide beam scanning performance verification. Both the measured and simulated results confirm that the fabricated array antenna can have a wide and consistent scanning range of ±50° in both E-plane and H-plane over 4.3:1 impedance bandwidth. In addition, low cross-polarization levels of less than -30.5 dB are achieved for the fabricated low top-to-ground profile (0.4λ<sub>h</sub>) TCDA antenna. |
