Study on on-Chip Antenna Design Based on Metamaterial-Inspired and Substrate-Integrated Waveguide Properties for Millimetre-Wave and THz Integrated-Circuit Applications

Abstract: This paper presents the results of a study on improving the performance parameters such as the impedance bandwidth, radiation gain and efficiency, as well as suppressing substrate loss of an innovative antenna for on-chip implementation for millimetre-wave and terahertz integrated-circuits. This was achieved by using the metamaterial and the substrate-integrated waveguide (SIW) technologies. The on-chip antenna structure comprises five alternating layers of metallization and silicon. An array of circular radiation patches with metamaterial-inspired crossed-shaped slots are etched on the top metallization layer below which is a silicon layer whose bottom surface is metalized to create a ground plane. Implemented in the silicon layer below is a cavity above which is no ground plane. Underneath this silicon layer is where an open-ended microstrip feedline is located which is used to excite the antenna. The feed mechanism is based on the coupling of the electromagnetic energy from the bottom silicon layer to the top circular patches through the cavity. To suppress surface waves and reduce substrate loss, the SIW concept is applied at the top silicon layer by implementing the metallic via holes at the periphery of the structure that connect the top layer to the ground plane. The proposed on-chip antenna has an average measured radiation gain and efficiency of 6.9 dBi and 53%, respectively, over its operational frequency range from 0.285–0.325 THz. The proposed on-chip antenna has dimensions of 1.35 × 1 × 0.06 mm3. The antenna is shown to be viable for applications in millimetre-waves and terahertz integrated-circuits.

Line managers’ views on adopting human resource roles: the case of Hilton (UK) hotels

Abstract: Purpose – The purpose of this paper is to explore different levels of line manager perspectives, namely strategic and first‐line on their role in human resource management (HRM) and human resource development (HRD), and to identify enablers of and barriers to devolving HR to line managers.Design/methodology/approach – Using a deductive approach, case study data was collected from 76 hotels, owned by Hilton UK, via self‐administered questionnaires to strategic and first‐line managers. Descriptive statistics were used to analyse the quantitative results, prior to significance tests being conducted in SPSS to identify differences in means based on managerial positions.Findings – A number of points of divergence in opinions are revealed, implying that there is potential for the case organisation to secure greater engagement of its first‐line managers in HR roles. Reducing the workloads and short‐term job pressures of these managers, together with capitalising on the good relations with the hotel HR specialist...
