Abstract

PURPOSE:To make it possible to use an extremely small antenna with efficiency by using the equivalent inductance component of a balancing antenna and the inductance component of a balance/imbalance transformer for matching. CONSTITUTION:When extremely small 1oop antenna 1 is connected to balance/ imbalance transformer T, a gyrator is interposed to attain a broad band. In general, the gyrator consists of capacitance CK and reactance LK. Here, LK can be excluded by setting reactance component L1 of antenna 1 and primary-side reactance component L2 of balance/imbalance converter T so that L1XL2<<LK, reducing a loss due to the reactance component. In parallel to the reactance component of antenna 1 and reactance component L2 of balance/imbalance converter T, capacitances C1 and C2 are provided to constitute a double tune circuit, thereby attaining a broad band.
