WIDEBAND LOW-PROFILE EIGHT-PORT EIGHT-WAVE ANNULAR-RING PATCH ANTENNA BASED ON USING EIGHT DUAL-SHORTED DUAL-RESONANT RING SECTORS FOR 8 × 8 MIMO MOBILE DEVICES

A wideband eight-port eight-wave annular-ring (AR) patch antenna for $8 imes $ 8 MIMO mobile devices is presented.The AR patch antenna is formed into eight dual-resonant 45o-ring sectors to radiate eight very-low-correlated or generally uncorrelated waves for $8 imes $ 8 MIMO application.Each ring sector is loaded with two shorting pins and excited

In view of the characteristics of distribution network with large-scale integration of distributed generation ORG SUNFLOWER SEEDS when single-phase grounding fault occurs, such as complex structure and operation mode, obscure electrical quantity after fault, weak fault characteristics and so on, this paper proposes a new fault location method for a
