손목시계폰용 새로운 안테나가 제안됐다. 제안된 안테나는 손목시계 전화기의 캡을 따라 있는 5.5파장 직사각형 루프입니다. 루프는 경첩으로 손목시계 케이스에 연결된 개방형 캡 주변에 장착됩니다. 안테나 이득을 논의하기 위해 우리는 두 가지 다른 조건을 다음과 같이 정의합니다. 사용자가 캡을 열고 손목시계폰으로 통화할 때, 손목이 얼굴 앞으로 오게 되는데, 이를 본 논문에서는 "대화 자세"라고 한다. 사용자가 캡을 닫고 전화를 기다릴 때 손목이 옆으로 눕는 것을 '대기 위치'라고 합니다. 제안하는 안테나의 방사 패턴을 측정하고 패턴 평균 이득(PAG)을 계산했습니다. 두 입장. 또한 제안한 안테나를 스트랩에 고정한 PIFA(Planar Inverted F Antenna) 안테나와 케이스에 장착한 NMHA(Normal Mode Helical Antenna) 안테나와 비교해 보았다. 그 결과, 제안한 안테나의 PAG는 약 -3dBd로 Talk 위치에 대한 다른 안테나의 PAG와 동일한 값을 보였다. 대기 위치의 경우 제안한 안테나의 PAG는 약 -7dBd로 다른 안테나에 비해 XNUMXdB 높았다. 제안된 안테나의 이득은 머리 근처에 고정되는 휴대용 전화기의 휩 안테나의 PAG인 목표에 도달했습니다. 결과는 제안된 안테나가 손목시계 휴대폰에 적합하다는 것을 보여줍니다.

Abstract: A new antenna for a wristwatch phone is proposed. The proposed antenna is a one-wavelength rectangular loop along the cap of the wristwatch phone. The loop is fitted at the periphery of the openable cap connected to the wristwatch case by a hinge. In order to discuss the antenna gain, we define the two different conditions as follows. When the user opens the cap and talks over the wristwatch phone, his wrist is held in front of his face, which is called the "talk position" in this paper. When the user closes the cap and waits for a call, his wrist rests down at the side, which is called the "stand-by position. " We measured the radiation patterns and calculated the pattern averaging gain (PAG) of the proposed antenna for the two positions. In addition, we compared the proposed antenna with the other antennas: a planar inverted F antenna (PIFA) fixed on the strap and a normal mode helical antenna (NMHA) installed on the case. As a result, the PAG of the proposed antenna was about -5.5 dBd, which was the same as the PAG of the other antennas for the talk position. In the case of the stand-by position, the PAG of the proposed antenna was about -3 dBd, which was 7 dB higher than that of the other antennas. The gains of the proposed antenna reached the goal, which was the PAG of a whip antenna of a handy phone held near the head. The results demonstrate that the proposed antenna is suited to a wristwatch phone.
