Abstract :
A new miniaturized multilayer ultrawideband (UWB) monopole antenna on the low-temperature co-fired ceramic (LTCC) is presented. This antenna is composed of two open asymmetrical rectangular loops and microstrip feed lines. The two open asymmetrical rectangular loops are seperated on different layers and partly overlaped with each other, which not only enhances the bandwidth but also minimizes the size of the overall antenna. The via holes are fully utilized to connect the radiation elements and microstrip feed lines on various layers of the LTCC substrate. The simulated and measured impedance and radiation performance are studied and compared, which shows that the proposed antenna provides a wide bandwidth from 3.6-10.6 Ghz.
