Abstract :
A novel differential-fed patch antenna (DFPA) is proposed in this letter. The proposed DFPA can be conveniently integrated with microwave differential circuits. Based on this differential feeding structure, wide bandwidth and good radiation patterns can be obtained. As a demonstration, a DFPA is designed and measured. Experiments show that the proposed DFPA can obtain good patterns with symmetric copolarization and low cross-polarization across a bandwidth of 34.5%
