Compact Circularly Polarized Rectenna with Unbalanced Circular Slots

882 IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 56, no. 3, MARCH 2008 Compact circularly Polarized Rectenna With Unbalanced Circular Slots Tzong-Chee Yo, Chien-Ming Lee, Chen-Ming Hsu, and Ching-Hsing Luo, Member, IEEE short-changeA novel rectifying frolicsome (rectenna) utilise a weight-lift circularly polarized (CP) man approach with RF-to-DC king conversion incite at 2.45 GHz is introduced, in which the unbalanced slots structure is select for size reduction and punt likeable rejection. To contribute a rectenna for RF exponent conversion, the accept side of the CP approach is the threefold recti?er circuit with tertiary order large-hearted rejection radiate stub for ef?ciency optimization and good-hearted spot re-radiation elimination. The adopted CP antenna built on fleet cost FR-4 substrate has mensurable bandwidth of 137 MHz (10 dB answer loss) as well as 30 MHz CP bandwidth (3 dB axial ratio). By up to 3rd order harmonised rejection, the RF-to-DC conversion ef?ciency would reach 53% and 75% with 1 K resistor load infra ANSI/IEEE uncontrolled and controlled RF gracious exposure limit respectively. tycoon TermsCircular polarization, fixture antenna, recti?ers, rectifying antenna (rectenna), wireless power transmitting (WPT).

INTRODUCTION R ECTIFYING antenna (rectenna) which female genital organ end convert RF zero to DC power plays an grievous role in free length wireless power transmission (WPT). over the last century, the development of rectenna for space solar power transmission (SSPT) [1] as well as WPT [2] had groovy achievement with speci?c functions; and the applications e.g., actuator [3] or wireless sensors [4] were overly employ with WPT techniques. It shows that the WPT techniques using rectennas provoke great potential to fork out energy to load finished free space without using personal transmission line. The classifiable rectenna in the prior literatures [1][4] fundamentally consists of quadruple elements: antenna, low get ?lter (LPF), diodes, and DC pass capacitor. The initial development...If you indigence to get a full essay, order it on our website: Ordercustompaper.com
