Beschreibung
Zusammenfassung:	An antenna structure includes a dielectric layer and an antenna unit disposed on a top surface of the dielectric layer. The antenna unit includes: a radiator comprising convex portions and concave portions; a transmission line extending in different directions and including a first transmission line and a second transmission line connected to the radiator; a parasitic element disposed adjacent to the transmission line and electrically and physically separated from the transmission line and the radiator. The length of the parasitic element in the extension direction of the transmission line is 45 to 70% of the half wavelength (λ/2) of the maximum resonant frequency from the antenna unit. The present invention provides the antenna structure having improved radiation characteristics and space efficiency. 안테나 구조체는 유전층, 및 유전층의 상면 상에 배치된 안테나 유닛을 포함한다. 안테나 유닛은 볼록부들 및 오목부들을 포함하는 방사체, 서로 다른 방향으로 연장하며 상기 방사체에 연결된 제1 전송 선로 및 제2 전송 선로를 포함하는 전송 선로, 전송 선로에 인접하게 배치되며 전송 선로 및 방사체와 전기적, 물리적으로 분리된 기생 소자를 포함한다. 기생 소자의 전송 선로의 연장 방향으로의 길이는 안테나 유닛으로부터의 최대 공진 주파수의 반파장(λ/2)의 45 내지 70%이다.
