Abstract-This paper presents the development of a standard surface mountable ceramic ball grid array (CBGA) package with an integrated patch antenna in low temperature cofired ceramic (LTCC) technology for emerging single-chip 60-GHz radios. It addresses the challenges of low-loss wire bonding interconnections required between the chip and the antenna as well as the package to allow efficient utilization of available space for miniaturization. The compact package of size 12.5×8×1.265 mm 3 achieves good electrical performance. For instance, the package part exhibits insertion loss < 0.08 dB, return loss > 22 dB, and attenuation rate < 0.2 dB/cm below 5 GHz; while the antenna part demonstrates 8-GHz impedance bandwidth and 8 ± 2 dBi peak realized gain at 60 GHz. Simulated and measured results are compared. They agree reasonably well, indicating the feasibility of designing and manufacturing the integrated antenna package in LTCC for millimeterwave applications.

This paper presents the design of a fully packaged 60 GHz wideband patch antenna incorporating an air cavity and a fused silica superstrate. Circular polarization (CP) is realized by introducing a diagonal slot at the center of the square patch. By optimizing the patch and the slot dimensions, a high efficiency (>90%) microstrip fed CP antenna with an impedance bandwidth of 24% and a 6 dB axial ratio bandwidth of 21.5% is designed. A coplanar waveguide (CPW) to microstrip transition with λ/4-open-ended stubs are then designed to match the antenna to the CPW packaging interface. The experimental results of the final packaged antenna agree reasonably with the simulation results, demonstrating an impedance bandwidth of more than 26% and a 6 dB axial ratio bandwidth of 22.7%.

In this paper a novel differentially fed Ultra-Wide Band (UWB) antenna in low-temperature co-fired ceramics (LTCC) technology to be used in the 60 GHz band for integrated RF front-ends is presented. The antenna is based on the aperture stacked patch fed via H-shaped aperture to achieve more than 10 GHz operational bandwidth. The antenna is fed by a parallel-wire transmission line which enables the antenna to be directly integrated with differential Monolithic Microwave Integrated Circuits (MMICs). To alleviate influence of the surface waves (efficiently excited in LTCC material due to its high dielectric constant) on the antenna radiation and realize uni-directional radiation patterns, a dedicated shield is added to the antenna. The measured results of the shielded antenna showed that the antenna has an operational bandwidth from 51 GHz to over 65 GHz, the gain is about 3.5-8 dBi, and 25 dB beamwidth is about +308. The measurement results also demonstrated that the shield indeed improves the antenna impedance bandwidth, gain, and radiation patterns substantially. I . I N T R O D U C T I O NThe demand for using the unlicensed 60 GHz band for communication and radar applications is growing rapidly. The large available bandwidth in the 60 GHz band is appealing to high data rate multimedia communications. Furthermore, the 60 GHz band is very suitable for ultra-high-resolution imaging with short-range radar, thus it is attractive for such application as concealed weapon detection (CWD) [1]. These demands have motivated many developments in the 60 GHz systems, especially in the integrated 60 GHz front-end. The low-temperature co-fired ceramics (LTCC) technology provides an effective solution enabling integration of passive components including antennas and filters with MMICs in a single, cost-effective package. In addition, the multilayer nature of LTCC technology gives the possibility to realize three-dimensional structures such as cavities and vias. The passive components can then be placed at different layers, which enable miniaturization of modules. Therefore, the research of integrated LTCC antennas is very popular, such as in [2][3][4]. Challenges of realizing antennas with the LTCC material in the mm-wave region are related to fabrication accuracy and limitations on structures such as lines, metal plates, or vias. In addition, high relative permittivity of the LTCC material may limit the bandwidth of the antenna and supports excitation of the surface waves in the substrate. As a result, several attempts have been used to lower the effective dielectric constant such as using an air cavity [5,6] or punching holes [7]. However, these approaches will complicate the manufacturing of the antenna, lower the yield rate, and increase cost. The operational bandwidth of LTCC antennas reported in literature is typically below 18% [6,8].This paper presents a novel differentially fed UWB antenna for CWD imaging radar. The antenna should be manufactured using the LTCC technology to be ready for integration with 60 GHz MMICs ...
