宽带双向微带天线 Two-way broadband microstrip antenna

技术领域 Technical Field

[0001] 本发明涉及一种微带天线,尤其是涉及一种可用于移动通信直放站的DCS1800通信协议,在平行四边形振子体开槽的宽带双向微带天线。 [0001] The present invention relates to an antenna, in particular, it relates to a mobile communications repeater for DCS1800 communication protocol, parallelogram vibrator body slotted two-way broadband microstrip antenna.

背景技术 Background

[0002] 直放站是目前移动通信系统中通常采用的,用于提高移动通信覆盖广度和通信容量的设备。 [0002] The repeater is usually used in a mobile communication system for mobile communication coverage range and increase the communication capacity of the device. 直放站通常应用在一些特殊应用场景,如窒内走廊、狭窄街道、隧道、高速公路,在这些场合中,一般要求直放站天线应具有:双向辐射、宽频带、高增益特性。 Repeater usually used in some special application scenarios, such as smothering the corridor, the narrow streets, tunnels, highways, in these cases, the general requirements repeater antenna should have: two-way radiation, wide bandwidth, high gain characteristics. 同时,为了进一步减小天线设备的体积,要求天线要具有低剖面特性。 Meanwhile, in order to further reduce the size of the antenna device is required to have a low profile antenna characteristics.

[0003]目前,已经有部分的研究人员做过关于具有双向辐射特性的天线的研究,提出了多种实现双向特性的天线结构。 [0003] Currently, the researchers are already part of the research was done on a bi-directional antenna radiation characteristics, and proposed a variety of two-way characteristics of the antenna structure. 常见的结构有:平面阵列天线和两个背靠背定向天线[1~3]。 Common structure: planar array antennas and two directional antennas back to back [1-3]. LongshengLiu等人采用六个折合偶极子共线组阵,在两个端射方向实现了约9. 05dBi增益。 LongshengLiu, who used six equivalent collinear dipole array group, in both directions to achieve about endfire 9. 05dBi gain. 但阵列天线馈电结构复杂,天线面积较大[1]。 However, the complex structure of the array antenna feed, the antenna larger [1]. X. Li, L. Yang, S.-X. Gong等人利用偶极子天线组成阵列实现了可工作在2. 4/5. 8GHz的双频双向天线,在2. 4GHz和5. 8GHz频段上,天线在两端射方向上的方向系数分别达到4. 5〜5. 9dB和6. I〜8. 9dB[2]。 X. Li, L. Yang, S.-X. Gong, who use a dipole antenna consisting of an array can be achieved in 2. 4/5. 8GHz dual bi-directional antenna, the 2. 4GHz and 5. 8GHz band , the antenna factor on both ends of the radio direction respectively 4. 5~5. 9dB and 6. I~8. 9dB [2]. 也有相关的文献提出了利用单个天线元实现双向辐射特性。 Also related literature proposes using a single antenna element bidirectional radiation characteristics. 实现双向辐射特性的天线结构有:环形天线、嵌套于接地环的单(双)极天线[4~6]。 Bi-directional radiation characteristics of the antenna structure: loop antenna, nested in a single grounding ring (double) pole antenna [4-6]. 刘聪,薛锋章等人将一个单极子天线嵌套在一个U形的接地面上,实现了天线的双向特性,在所有的工作频点上天线在两个端射方向上的增益都在4. SdBi以上。 Cong, Xue Feng Zhang, who will be a monopole antenna is nested in a U-shaped ground plane to achieve the two-way characteristics of the antenna, in all working frequency of the antenna gain in both directions are endfire 4 . SdBi above. 但这些利用单个天线元实现双向特性的天线都是采用立体结构,无法实现低剖面。 But these using a single antenna element to achieve two-way characteristics of the antenna are using three-dimensional structure, we can not achieve low profile. H. Arai等人通过H形接地面和曲柄形馈电结构的微带天线,真正实现了双向辐射低剖面天线结构m。 H. Arai et al., The ground plane and the crank-shaped microstrip antenna feed structure through H-shaped, truly a two-way radiation low-profile antenna structures m. 如在两侧添加无源引向贴片,其端射增益可达到5. 71dBi[8]。 As both sides adding a passive toward patches, which endfire gain can be achieved 5. 71dBi [8]. 但该结构接地面需要H形开口,应用时要求离物理地面有一定高度。 However, the structure of the ground plane need H-shaped opening, when the application requires a certain height from the physical ground.
