A suspended shorted patch capacitively fed using an inverted L-shape feed is a compact antenna for wearable wireless sensors. A short microstrip line was printed on the sensor PCB to connect the antenna to a transceiver chip. The shorting of the suspended patch was done using printed silver ink on the side wall of a 22mm × 6mm × 6mm block of polycarbonate plastic that suspends the mounted patch. Based...
A High Frequency and High Power Density Wireless Planar Transformer (HFHPD-WPT) is a very attractive future technology which can provide power to an electric vehicle (EV) through a contactless charging system. In this paper, EMC computer modeling and simulation techniques are employed to investigate the magnetic flux distribution and associated EMC problems such as stray fluxes and hot spots. The...
Dielectric embedded electronically steerable multiple beam antenna array is a potential candidate in mobile wireless communications. However, its synthesis is challenging due to the existence of the large conflicting objectives and infeasibility of analytical synthesis techniques. In this regard, an extended evolutionary algorithm is proposed and tested using different case studies.
A novel circularly polarized smart patch antenna array with hexagonal elements was designed as a hub for indoor/outdoor mobile wireless computing networks. A frequency domain finite element method (FEM) was employed to design the patch antenna array using an optimization technique based on the gradient algorithm to optimize the physical structure on a finite ground plane for optimal directivity in...
The paper presents an electronically beam switched smart mobile terminal antenna (SMTA) array used in wireless network. SMTA arrays were optimized for the secured communication performance and desired radiation coverage. The radiation beam pattern toward desired direction is controlled by switched beam control algorithm. Four different configurations of SMTA arrays and their design considerations...
