One of the properties of high impedance surface is that the phase of the reflection wave by the surface is zero.A high impedance surface was used as antenna reflecting surface. A dipole antenna was designed as radiation source. Simulation demonstrated that when the patches number of surface changed the radiation pattern changed and the gain varied also. The distance between antenna and the reflection face varied the radiation pattern also changed. Controlling the number of cells or distance between antennas from reflection plane the gain of antenna can be improved.

High Impedance Surface

3D integration of heterogeneous modules including RF and millimeter-wave (mmW) functionalities is opening new challenges for packaging developers to conciliate between electrical performance, thermal behavior and mechanical reliability using cost-effective technologies. This paper deals with innovative integrated antenna solutions within the particular context of 3D heterogeneous integration on silicon interposer using a disruptive design approach. Novel integration schemes of antennas using a high-impedance surface (HIS) reflector are presented. Then, the design steps of a 60-GHz folded dipole antenna for short-range communications are detailed. Simulation and measurement results show promising performances in terms of gain and radiation efficiency. Process and fabrication issues are addressed with specific Back-End processing developments and an experimental validation is proposed.

In this paper, impedance matching enhancement of a grounded wearable low-profile loop antenna is investigated using a high-impedance surface (HIS) structure. The wearable loop antenna along with the HIS structure is maintained low-profile, making it a suitable candidate for healthcare applications. The paper starts with investigating, both numerically and experimentally, the effects of several textile parameters on the performance of the wearable loop antenna. The application of impedance enhancement of wearable grounded loop antenna with HIS structure is then demonstrated. Numerical full-wave simulations are presented and validated with measured results. Unlike the grounded wearable loop antenna alone with its degraded performance, the wearable loop antenna with HIS structure showed better matching performance improvement at the 2.45 GHz-band. The computed overall far-field properties of the wearable loop antenna with HIS structure shows good performance, with a maximum gain of 6.19 dBi. The effects of bending the wearable loop antenna structure with and without HIS structure as well as when in close proximity to a modeled human arm are also investigated, where good performance was achieved for the case of the wearable antenna with the HIS structure.
