摘要: An antenna structure with reduced bulkiness and capable of changing antenna directivity is provided. In order to achieve such an effect, the antenna structure includes a feed element of one of an inverted F type and a loop type, and a passive element of one of the inverted F type and loop type, and having a variable reactor so as to be capable of changing an electrical length, and the feed element and passive element are disposed with a predetermined distance therebetween.
