摘要：
An elliptical base rhombic monopole antenna and frequency notched EBRM are proposed for low loss omni-directional ultra-wideband applications. The impedance bandwidth of simple rhombic monopole is improved with the help of semi-elliptical base and optimized for impedance matching of the order of -15 dB within impedance bandwidth. Frequency notched EBRM is realized by a U-shaped slot and optimized for WLAN. The measured results confirm impedance matching level of -15 dB, notched function with insertion level of 1.68 dB and omni-directional coverage over the impedance bandwidth.
