The paper presents an antenna design of smart watch with WLAN MIMO antennas and a GPS antenna. The overall dimensions size of the design is 40 mm × 40 mm × 5.4 mm. There are four WLAN antennas and a GPS antenna in the design. The size of ground plane is 40 mm × 40 mm. The antennas are fed by 50-ohm mini coaxial cable line. The PIFA type is adapted to design the antennas of GPS (1.575 GHz) and WLAN...
The paper presents a design with four antennas on smart watch for GPS/UMTS/WLAN MIMO application. The overall dimensions of the design are 40 mm × 40 mm × 5.4 mm. The size of the main ground plane is 40 mm × 40 mm × 0.4 mm. These antennas are using the coupled-fed architecture. They are fed by 50-ohm mini coaxial cable lines. The four antennas are placed vertically to the edges of the main ground...
This paper presents a printed antenna with an open slot in ground plane for wireless applications. The modes of the antenna ground and the open slot are excites to form the bandwidth at LTE 2300 and LTE2500 MHz while the two rectangular metal plates are excited to cover the bands for 5.2 and 5.8 GHz. The antenna with the overall dimensions of 55×13×1.6 mm3 consists of an antenna portion of 10×13 mm...
In this paper, a multi-band monopole antenna for Universal Serial Bus (USB) dongle applications is proposed and examined. The antenna is fabricated on an FR4 substrate of permittivity of 4.4, thickness of 0.8 mm, and loss tangent of 0.0245.The antenna consists of a bent monopole and an inserted strip horizontally. The bent monopole resonates a mode operation at 2.4 GHz and 5.2 GHz. The L-shaped monopole...
In this paper, we propose block-level replacement techniques for content-addressable memories. The CAM array is first divided into row banks and column banks. Then, for each divided array (the overlapped CAM cells of a row bank and a column bank), two redundant row blocks are added and reconfiguration is performed at the block level instead of the conventional word level. According to simulation results,...
