Design for Circularly Polarized Microstrip Cross Dipole Array Antenna by Electromagnetic Coupled Technique
전자기적 결합을 이용한 원편파 크로스-다이폴 마이크로스트립 어레이 안테나의 설계
Abstract
This paper describes a design for microstrip EMC cross dipole array antenna with circular polarization. To realize the wide bandwidth and circular polarization, the electromagnetic-coupled cross dipole is used. To obtain the uniform aperture illumination, offset technique for array is adopted. In 20-element array design, the calculated axial ratio and gain are about 0.1 dB and 9.9 dBi at 12GHz, respectively. The frequency characteristics of a fabricated 20-element array antenna are measured. The calculated results agree well with the measured ones.
