이러한 본 발명은 본체, 상기 본체의 일측 단부에 회전 개폐되도록 힌지 결합되는 덮개로 이루어진 휴대폰에 있어서, 상기 본체의 일측면으로 인출 가능하게 설치되어 전파를 수신하는 제 1안테나; 및 상기 덮개내의 표시창과 평행하게 배열 설치하여 전파를 송신토록 하고, 상기 표시창과의 사이에 차단판으로 격리되는 제 2안테나를 포함하여 구성함으로써 달성되는 것이다.The present invention is a mobile phone consisting of a main body, a cover that is hinged to be rotated to open and close at one end of the main body, the first antenna is installed to be retractable to one side of the main body to receive radio waves; And a second antenna arranged in parallel with the display window in the cover to transmit radio waves, and isolated from the display window by a blocking plate.

이하, 본 발명의 바람직한 실시예는 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 루프 안테나를 갖는 휴대폰을 보여준 도면이다. 도 2는 도 1에서 루프 안테나의 대략적인 배치 상태를 보여준 도면이다. 도 3은 본 발명의 실시예에 따른 제 1,2 안테나의 수신 및 송신 상태를 보인 참고도면이다.1 is a view showing a mobile phone having a loop antenna according to an embodiment of the present invention. FIG. 2 is a diagram illustrating a schematic arrangement of a loop antenna in FIG. 1. 3 is a reference diagram illustrating reception and transmission states of first and second antennas according to an exemplary embodiment of the present invention.

이에 도시된 바와 같이, 도면 부호 "H"는 본 발명의 휴대폰이다. 휴대폰(H)은 본체(100)의 일측 단부에 덮개(102)를 회전 개폐되도록 힌지 결합되는 덮개로 이루어진다.As shown here, reference numeral "H" denotes a mobile phone of the present invention. Mobile phone (H) is made of a cover that is hinged to open and close the cover 102 to one end of the main body 100.

제 1안테나(110)는 본체(100)의 일측면으로 인출 가능하게 설치된다. 제 1안테나(110)는 공지의 다이폴 안테나(Dipole antenna)를 이용한다. 제 1안테나(110)는 전파의 수신을 담당한다.The first antenna 110 is installed to be withdrawn to one side of the main body 100. The first antenna 110 uses a known dipole antenna. The first antenna 110 is responsible for receiving radio waves.

제 2안테나(112)는 덮개(102)내의 표시창(120)과 평행하게 배열 설치한다. 제 2안테나(112)는 전파의 송신을 담당한다. 제 2안테나(112)는 공지의 루프 안테나(Loop antenna)를 이용한다. 제 2안테나(112)는 표시창(120)과의 사이에 차단판(130)으로 격리된다. 차단판(130)은 구리와 같은 재질로 하여 전자파가 차단될 수 있도록 한다.The second antenna 112 is arranged in parallel with the display window 120 in the cover 102. The second antenna 112 is responsible for transmitting radio waves. The second antenna 112 uses a known loop antenna. The second antenna 112 is isolated by the blocking plate 130 between the display window 120 and the second antenna 112. The blocking plate 130 is made of a material such as copper so that electromagnetic waves can be blocked.

이와 같이 구성된 본 발명 루프 안테나를 갖는 휴대폰에 대한 작동 상태에 대해 자세하게 설명하고자 한다.It will be described in detail the operating state for the mobile phone having a loop antenna of the present invention configured as described above.

전체적으로 볼 때, 본 발명의 휴대폰(H)은 제 1안테나(110)를 이용한 전파의 수신 부분과 제 2안테나(112)를 이용한 전파의 송신 부분으로 크게 대별된다. 즉,기존에는 제 1안테나(110)가 전파의 수신 및 송신을 담당했으나, 본 발명에서는 제 1안테나(110)와 제 2안테나(112)가 각기 전파의 수신 및 송신을 담당하게 된다. 일반적으로, 제 1안테나(110)를 이용한 전파의 수신 신호는 미약하고, 제 2안테나(112)를 이용한 전파의 송신 신호는 제 1안테나(110)에 비해 상대적으로 강하다.In general, the mobile phone H of the present invention is roughly divided into a reception portion of the radio wave using the first antenna 110 and a transmission portion of the radio wave using the second antenna 112. That is, although the first antenna 110 was in charge of the reception and transmission of the radio waves, in the present invention, the first antenna 110 and the second antenna 112 are respectively responsible for reception and transmission of the radio waves. In general, the reception signal of the radio wave using the first antenna 110 is weak, and the transmission signal of the radio wave using the second antenna 112 is relatively stronger than the first antenna 110.

도 3을 참조하면, 전파는 휴대폰(H)의 제 1안테나(110)를 통해 전달 받아 대역필터(140)로 전달된다. 그 대역필터(140)에서는 주어진 상부 및 하부 차단 주파수만을 통과시켜 저잡음 증폭기(142)로 전달시켜 증폭 변조한다. 그 증폭된 전파는 송수신부(144)로 전달되는 것이다. 그 송수신부(144)에서는 파워 증폭기(146)로 전달되어 0.1mW ~ 200mW의 범위까지 크게 증폭시킨 후, 제 2안테나(112)를 통해 외부로 송신한다.Referring to FIG. 3, the radio wave is received through the first antenna 110 of the mobile phone H and transmitted to the band pass filter 140. The band filter 140 transmits only the given upper and lower cutoff frequencies to the low noise amplifier 142 for amplification and modulation. The amplified radio wave is transmitted to the transceiver unit 144. The transceiver 144 transmits the power amplifier 146 to the power amplifier 146 and amplifies it to a range of 0.1 mW to 200 mW.

이 과정에서, 제 1안테나(110)에는 상대적으로 미약한 전파 신호를 수신받기 때문에 그만큼 전파에 의한 폐해는 최소화된다. 아울러, 제 2안테나(112)에는 증폭된 신호가 외부로 송신되지만, 구리와 같은 재질로 이루어진 차단판(130)이 덮개(102)에 설치되어 전파가 인체에 전달되는 것을 차단한다.In this process, since the first antenna 110 receives a relatively weak radio signal, the damage caused by radio waves is minimized. In addition, although the amplified signal is transmitted to the second antenna 112 to the outside, a blocking plate 130 made of a material such as copper is installed on the cover 102 to block the transmission of radio waves to the human body.

이상에서 상세히 설명한 바와 같이, 본 발명의 루프 안테나를 갖는 휴대폰에 따르면, 본 발명의 휴대폰에는 전파의 수신을 담당하는 제 1안테나와 전파의 송신을 담당하는 제 2안테나를 함께 구비함으로써, 미약한 수신 신호는 제 1안테나에 의해 전달받게 하고, 크게 증폭된 전파의 송신 신호는 제 2안테나에 의해 송신토록함에 따라, 전파의 송수 전파의 간섭을 배제하여 통화의 품질 향상을 꾀할 수 있다.As described in detail above, according to the cellular phone having the loop antenna of the present invention, the cellular phone of the present invention is provided with a first antenna that is responsible for the reception of radio waves and a second antenna that is responsible for the transmission of radio waves, thereby faint reception. Since the signal is transmitted by the first antenna and the transmission signal of the largely amplified radio wave is transmitted by the second antenna, it is possible to improve the call quality by eliminating the interference of the transmission and reception of the radio wave.

아울러, 제 1안테나에 비해 상대적으로 강한 전파를 송신하는 제 2안테나는 차단판에 의해 휴대폰 사용자와 격리시킴으로써, 강한 전파가 사용자의 인체로 전달되는 것을 방지함에 따라, 전파에 의한 인체의 폐해를 최대한 예방할 수 있다.In addition, the second antenna, which transmits a stronger radio wave than the first antenna, is isolated from the mobile phone user by the blocking plate, thereby preventing the strong radio wave from being transmitted to the user's human body, thereby minimizing harm to the human body due to the radio wave. It can be prevented.

이상에서 설명한 것은 본 발명에 따른 루프 안테나를 갖는 휴대폰을 실시하기 위한 하나의 실시예에 불과한 것으로, 본 발명은 상기한 실시예에 한정되지 않고, 이하의 특허청구범위에서 청구하는 바와 같이 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described above is only one embodiment for carrying out a mobile phone having a loop antenna according to the present invention, and the present invention is not limited to the above-described embodiment, as claimed in the following claims. Without departing from the gist of the present invention, one of ordinary skill in the art will have the technical spirit of the present invention to the extent that various modifications can be made.
