摘要: A compact diversity antenna operating at an ultrawideband (UWB) frequency range of 3.1-5 GHz is proposed for use in portable devices. The printed on a circuit board (PCB) slab consists two notched triangular radiating elements with feeding ports. ground plane etched the reverse side PCB. shape optimized to improve isolation between ports as well impedance matching. simulated and measured results show that across bandwidth, can achieve broad bandwidth good performance terms -2 dBi, efficiency > 70%. correlation radiation patterns shows consistent UWB bandwidth. method derive thetransfer function has been proposed, which be used obtain radiated pulses time domain. Furthermore, parametric study conducted provide engineers useful information designing optimizing antenna.
