A study on circular microstrip antenna using rigorous probe feeding model = 정확한 급전 구조를 고려한 원형 마이크로스트립 안테나 연구

Circular microstrip antenna has been analyzed by the Green``s function/Method of Moment(MoM) by using rigorous probe feeding model for accurate result. These problems include radiation and scattering from isolated circular patch and input impedance of circular patches. In this study, the patches are probe-fed via the center conductor of a coaxial transmission line. The probe feed is modeled as a short electric line current which excites current on the patch. This idealized probe feed model approach ignores the probe self-impedance as well as the rapidly-varying patch current in the vicinity of the feed connection point. Later, a rigorous probe feed model which overcomes these deficiencies is developed and used in the analysis of both isolated circular patches. Microstrip antenna would be used with radome because it provides the advantages of protecting antenna from environmental hazard, enhancing the antenna gain. An additional topic investigated is the effect of suspending a dielectric layer above the substrate. Using the attachment mode, the algorithm for analyzing circular patch antenna with radome is realized. We implemented the algorithm and verify it with experiment.
