摘要: In this paper a novel differentially fed Ultra-Wide Band (UWB) antenna in low-temperature co-fired ceramics (LTCC) technology to be used the 60 GHz band for integrated RF front-ends is presented. The based on aperture stacked patch via H-shaped achieve more than 10 operational bandwidth. by parallel-wire transmission line which enables directly with differential Monolithic Microwave Integrated Circuits (MMICs). To alleviate influence of surface waves (efficiently excited LTCC material due its high dielectric constant) radiation and realize uni-directional patterns, dedicated shield added antenna. measured results shielded showed that has an bandwidth from 51 over 65 GHz, gain about 3.5–8 dBi, 25 dB beamwidth about+308. measurement also demonstrated indeed improves impedance bandwidth, gain, patterns substantially.
