摘要： A top-loaded monopole antenna apparatus having a feeding point is provided for use in a communication system such as a mobile communication system or the like. The top-loaded monopole antenna apparatus includes a grounding conductor, a top-loading electrode, a linear conductor element, and a short-circuit conductor. The top-loading electrode is provided so as to oppose to the grounding conductor. The linear conductor element electrically connects the feeding point with the top-loading electrode, and the short-circuit conductor electrically connects the top-loading electrode through a reactive element to the grounding conductor. This structure leads to a height lower than that of prior art, and easy impedance matching.

摘要： The antenna of the present invention comprises flat-plate ground plane 1, first antenna element 13 with one end 13a connected to feeding point 2 and intermediate portion 13b folded by a plurality of times, which is extended upward from the ground plane 1, and second antenna element 23 with one end 23a connected to the other end 13c of the first antenna element 13, with intermediate portion 23b formed in symmetrical relation to the first antenna element 13, and also, with the other end 23c connected to the ground plane 1. Thus, it is possible to obtain a small size antenna with the antenna element lowered in height.
