This paper reviews proposed realization concepts and achievements of wireless sensor nodes and focuses on new developments in the 24 GHz frequency range. The relatively high frequency offers the advantage of ultra miniaturization and therefore opens new application fields. On the other hand power consumption of the RF-front-end becomes still more challenging than at lower frequencies. It is shown that by applying very simple CMOS transceiver architectures and modulation schemes combined with innovative efficient wake-up concepts, very low energy consumption can be achieved. Technological realization concepts and first experimental results from a 24 GHz demonstrator as well as novel special purpose wakeup-circuitry are presented, too.

“…To date, much research has focused on planar antenna designs for quasi millimeter-wave applications using PCB or LTCC technologies [3][4][5]. However, highly integrated sensor node platforms comprise compact 3D stacks, where the antenna is integrated in one of the stack modules [6][7][8]. For this purpose, antenna designs suitable for 3D stacks and thin film processing have been reported.…”

Three patch antennas suitable for integration and operation in a compact 24 GHz wireless sensor node with radar and communication functions are designed, characterized, and compared. The antennas are manufactured on a low loss glass wafer using thin film (BCB/Cu) wafer level processing (WLP) technologies. This process is well suited for 3D stacking. The antennas are fed through a microstrip line underneath a ground plane coupling into the patch resonator through a slot aperture. Linear polarization (LP), dual mode (DM) operation, and circular polarization (CP) are achieved through the layout of the slot aperture and rectangular patch dimensions. Antenna gain values of ∼5.5 dBi are obtained in addition to the 10 dB impedance bandwidths of 900 MHz and 1.3 GHz as well as 500 MHz CP bandwidth with a 3 dB axial ratio for the LP, DM, and CP patch antennas, respectively.

“…Song et al [14] worked on a complete RF front end and its antenna on a single chip operating à 2.4 GHz. And Talukder et al [15] presented a slot antenna at 24 GHz realized using flip-chip technology and allowing integration of active chips into it. However, when reducing dimensions, problems occur when the antenna is packaged.…”

This paper reports on the design of a package-antenna operating at 2.4 GHz which can be used in wireless sensor network (WSN) nodes. The goal of this study is to reduce the size of WSN nodes by decreasing the antenna dimensions, found as a major contributor in the final node size. As the transceiver is packaged by the antenna, we focused our investigations on the influence of the transceiver size and position on the radiation characteristics of the antenna. Furthermore, the influence of environment where the antenna is placed was done. The optimisation of this 3D antenna is made using an electromagnetic simulator and comparison with measurement shows a good agreement.
