Abstract: We report our investigation into single-feed dual-frequency planar inverted F antenna (PIFA) designs which make use of LC resonators (or “RF traps”). We introduce three basic methods for incorporating the LC resonator into the PIFA, including a variant of the meandering PIFA. Experimental results are provided and these show that dual-frequency operation at 900 (cellular systems) and 1800 MHz (personal communication systems) can be achieved for all three designs

Abstract: We present the design of a microstrip, dual-frequency planar inverted-F antenna (DF-PIFA) for mobile telephone handsets that can concurrently work at two frequency bands, viz., the GSM and DCS 1800 systems, which operate at 0.9 and 1.8 GHz, respectively. A computer-aided design (CAD) tool, based on the non-uniform finite difference time domain (NU-FDTD) Maxwell solver, is employed to optimize the performance characteristics of the DF-PIFA, including the return loss, impedance match, frequency bandwidth and the far-field radiation pattern

版主周末都不回答问题?
版主要回答问题,你做到了吗?
hefang你是CST公司的吧,说点儿有用的!
你是做天线的吗?不懂不要说外行的话!
你要是不懂就shut up!
相信我,没有你论坛会更好。
