Abstract

In this paper, a multiband LTE antenna satisfying LTE octa-band is proposed. The proposed antenna consists of a modified PIFA structure and a folded monopole which has the height of 4 mm. Each parts operates at lower and upper LTE band. Measured bandwidth(6 dB return loss) was 118 MHz(870~988 MHz) at the lower band and 1,107 MHz(1,650~2,757 MHz) at the upper band. The proposed antenna has a omni-directional radiation pattern and measured peak gains were 3.21 dBi at the lower band and 4.19 dBi at the upper band, respectively. The proposed antenna is expected to be utilized for future LTE-advanced system.

본 논문에서는 8개의 LTE 대역을 만족하는 다중 대역 LTE 안테나를 제안하였다. 제안된 안테나는 변형된 PIFA 구조와 4 mm의 높이를 갖는 folded monopole 구조가 결합된 형태로 구성되어 있으며, 각각의 구조가 LTE 하위 대역과 LTE 상위 대역에서 동작한다. 안테나의 측정된 6 dB 반사 손실 대역폭은 하위 대역에서 118 MHz(870~988 MHz), 상위 대역에서 1107 MHz(1,650~2,757 MHz)이다. 제안된 안테나는 전방향성 방사 패턴을 가지며, 측정된 최대 이득은 하위 대역에서 3.21 dBi 상위 대역에서 4.19 dBi의 값을 갖는다. 제안된 안테나는 향후 LTE-advanced 통신 시스템에 적용될 수 있을 것으로 기대된다.
