Circularly Polarized Patch Antennas Combining Different Shaped Linealy Polarized Elements
Graduate School of Engineering, Chiba University, Chibashi, 263–8522 Japan 広帯域な円偏波特性をもつアンテナとしては,軸 モードのヘリカルアンテナ [2] や,直交する 2点から 90◦ 位相差で給電するパッチアンテナ [3] が報告され ている.一般に衛星通信移動局用アンテナでは,前述 の広帯域特性をもつアンテナをアレー化して利用して いる.ゆえに,10%程度の周波数帯域幅をもつ円偏波 の素子アンテナが必要となる.これまでに,このよう な衛星通信システムに適用可能な円偏波アレーアンテ ナの構成法について,いくつかの報告がなされている. 報告例を大別すると,広帯域な円偏波特性をもつ素子 アンテナで必要な帯域幅を確保する方法 [4]~[6] とア レーアンテナの構成を工夫して必要な帯域幅を確保す る方法がある [...
متن کاملCircularly Polarized Broadband RFID Microstrip Tag Antenna
In recent years, the application of radio frequency identification (RFID) operating in the ultra-high frequency (UHF) band (860-960MHz) are expanding exponentially, due to the advantages such as long reading distance, high data transfer rate, and small tag size. So the design of a CP tag antenna with broadband characteristic is presently one of the most challenging topics. This project presents...
متن کاملAutomatic Design of Broadband Gradient Index Metamaterial Lens for Gain Enhance- Ment of Circularly Polarized Antennas
A broadband gradient index (GRIN) metamaterial lens for gain enhancement of circularly polarized antennas has been automatically designed, fabricated and investigated. The GRIN metamaterial lens consists of an isotropic dielectric plate with a corresponding distribution of deep-subwavelength drill holes each with the same diameter. Such drill holes have a negligible influence on both the polari...
متن کاملDesign and Implementation of Dual-band Circularly Polarized Antennas Using Stacked Patches
Single and Dual feed Antennas with dual frequencies have been demonstrated. Varactor diodes are used for independent tuning. The PIFA (Planar Inverted F-Antenna) has two frequencies from 0.7 to 1.1 GHz and from 1.7 to 2.3GHz. Impedance match of about -10dB an isolation greater than 13dB is obtained. The single feed antenna can be tuned from 1.2 to 1.6GHz and 1.6 to 2.3 GHz. The antenna volumes ...
متن کاملDesign Method for Circularly Polarized Fabry-Perot Cavity Antennas
A new class of circularly polarized (CP) Fabry-Perot cavity antennas is introduced that maintain the simplicity of a linearly polarized primary feed and a single cavity structure. The proposed antennas employ a double-sided partially reflective surface (PRS), which allows independent control of the magnitude and phase responses for the reflection and transmission coefficients. In conjunction wi...
