Research Abstract |
A theoretical method for calculating the characteristics of an extremely small antenna with an arbitrarily shaped structure has been established, where an integral equation is formulated for the current along the antenna conductor. The kernel of this equation does not include calculations of derivatives and integrations, thereby leading to easy treatment with a reduced computation time. The integral equation has been applied to a spiral structure and solved using the method of moments. Based on the obtained results, an extremely small spiral antenna has been realized.
