오늘날의 다양한 무선 시스템을 통한 서비스의 공존은 간섭 문제를 야기시킬 수 있으며, 제한된 주파수 대역을 효율적으로 활용하기 위해서는 보다 정확하고 효과적인 주파수 공유 기술에 대한 연구가 필수적이라고 할 수 있다. 특히 위성시스템이 가지는 광역성으로 인하여 지상시스템과의 주파수 공유는 필수적이다. Ka 대역 주파수를 사용하는 위성 시스템은 지향성 안테나를 사용하게 되므로 위성의 방위각을 고려한 주파수 공유 결과에 대한 분석은 주파수 효율성을 높이는데 매우 큰 역할을 할 수 있다. 본 논문에서는 위성망과 지상망과의 간섭을 안테나의 방위각을 고려하여 분석한 결과를 제시하고, 주파수 공유 시 요구되는 망간 최소 이격 거리를 분석한 결과를 제시함으로써 분석 결과가 실제 시스템 설계 및 구현에 활용될 수 있도록 하고 있다.
