【摘要】：超寬帶技術(shù)作為無(wú)線通信技術(shù)的重要組成部分,它被真正的使用是從二十世紀(jì)六十年代開(kāi)始的,最初它被用于雷達(dá)探測(cè),但在此后的一段時(shí)間內(nèi)寬帶技術(shù)發(fā)展較為緩慢。后來(lái)因?yàn)槠涓邆鬏斔俾�、保密性好、高增益、低功耗等原�?它成為國(guó)內(nèi)外學(xué)者研究和討論熱點(diǎn)。在已經(jīng)規(guī)定的超寬帶頻段內(nèi)還存在WiMAX(3.35 3.75GHz)、WLAN(5.725 5.85GHz)以及X波段衛(wèi)星系統(tǒng)的干擾,為了排除這些頻段的干擾人們開(kāi)始對(duì)陷波天線的研究。論文首先介紹超寬帶系統(tǒng)的一些理論基礎(chǔ)以及超寬帶天線的主要性能參數(shù),如增益、回波損耗、電壓駐波比等。其次論文設(shè)計(jì)了兩款超寬帶天線,圓形縫隙微帶天線和微帶饋電超寬帶天線。運(yùn)用仿真軟件對(duì)天線的某些參數(shù)進(jìn)行仿真,進(jìn)一步分析優(yōu)化最后得出最佳尺寸。這兩款天線在各個(gè)性能方面較為優(yōu)良,滿足超寬帶天線的工程要求。然后又設(shè)計(jì)了兩款單陷波的超寬帶天線,陷波頻率范圍選為5.15 5.85GHz,運(yùn)行仿真后天線的各項(xiàng)性能優(yōu)良,滿足陷波要求。此外還介紹一款雙陷波超寬帶天線,陷波頻段范圍選為3.35 3.75GHz和5.15 5.85GHz。最后設(shè)計(jì)的一款具有三陷波特征的天線,它在3.35 3.75GHz、5.15 5.85GHz、7.25 7.75GHz形成陷波,排除了這些頻段對(duì)于超寬帶通信系統(tǒng)的干擾。具有較大的實(shí)用價(jià)值。超寬帶技術(shù)在將來(lái)會(huì)成為短距離高速率無(wú)線通信技術(shù)的最佳選擇,而超寬帶天線是超寬帶通信系統(tǒng)用來(lái)發(fā)射和接收信號(hào)的關(guān)鍵器件。因此,超寬帶天線的研究與設(shè)計(jì)具有相當(dāng)大的研究潛力。
[Abstract]:Ultra-wideband (UWB) technology, as an important part of wireless communication technology, has been used since 1960s. At first, it was used in radar detection, but the development of broadband technology has been slow for some time since then. Later, because of its high transmission rate, high security, high gain, low power consumption and other reasons, it has become a hot topic of research and discussion at home and abroad. WiMAX (3.35 ~ 3.75 GHz) and X-band satellite system interference also exist in the prescribed UWB band. In order to eliminate the interference in these bands, people began to study the notch antenna. In this paper, the theoretical basis of UWB system and the main performance parameters of UWB antenna, such as gain, return loss, VSWR and so on, are introduced. Secondly, two UWB antennas, circular slot microstrip antenna and microstrip fed UWB antenna are designed. Some parameters of antenna are simulated by simulation software, and the optimum size is obtained by further analysis and optimization. These two antennas are excellent in various aspects and meet the engineering requirements of UWB antennas. Then, two UWB antennas with single notch wave are designed. The notch frequency range is 5.15 ~ 5.85 GHz. The simulated antenna has excellent performance and meets the requirements of notch wave. In addition, a dual-notch ultra-wideband antenna is introduced. The notch band ranges from 3.35 to 3.75 GHz and from 5.15 to 5.85 GHz. Finally, a three-notch antenna is designed, which forms a notch at 3.35 ~ 3.75 GHz ~ 5.15 ~ 5.85 GHz ~ 7.25 ~ 7.75 GHz, which eliminates the interference of these bands to UWB communication systems. It has great practical value. Ultra-wideband (UWB) technology will be the best choice for short-range and high-rate wireless communication technology in the future. UWB antenna is the key device for UWB communication system to transmit and receive signals. Therefore, the research and design of UWB antenna has great potential.
