Antenna and semiconductor device with improved tradeoff relationship between antenna gain and antenna size

摘要

An antenna including: a first conductor portion including a power supply point at which one of a pair of differential signals is input; a second conductor portion including a power supply point at which another one of the pair of differential signals is input, the second conductor portion being separated by a gap from the first conductor portion; and a third conductor portion that connects the first conductor portion with the second conductor portion, wherein the gap includes a portion having a width that becomes progressively wider in a direction moving away from the third conductor portion.
