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...
In the paper we presents a dual-open-slot antenna, with a overall size of 50 × 13 × 3.5 mm3. The antenna consists of a long-open-slot and a short-open-slot. The tail of the long-slot is bent for compact size. The dual-slot antenna is feed by an L-shaped microstrip line. The long-slot used in the 2.4GHz mode and short slot excitation in 5.2 GHz mode. The open slots are excited through the L-shaped...
In this paper, a folded C-shaped monopole for WLAN/WiMAX USB dongle is proposed. The antenna is fabricated on FR4 substrate; the overall dimensions are 35 mm × 10 mm × 1.6 mm. The antenna portion is occupied by 10 mm × 10 mm, and the size of system ground is 25 mm × 10 mm. The C-shaped monopole consists of the left arm with longest length and the left arm. The left arm of the folded C-shaped generates...
A design of MIMO antennas using two monopole structures adding a neutral line connected to ground plane for achieving better isolation is proposed and examined. The antenna uses curved C-shaped arm to resonance the bands of IEEE802.11b/g/n; another arm extended on the feed achieves the bands of IEEE 802.11a application. The overall size of the design is 45×25×1.6mm3; the occupied area of the antenna...
This paper presents an Inverted-F Antennas (IFAs) type MIMO antenna with Wi-Fi and Blue-Tooth band for smart watch application. The overall dimensions of 40×40×5.4 mm3 of the proposed design consisting of an antenna portion of 40×5×0.1 mm3 and system ground portion of 40×40×0.4 mm3. The antenna geometry is composed of two identical IFA antennas extended from the two side of the ground, which designed...
In this paper, a printed monopole antenna with simple structure, small size, and easy to design is proposed. The antenna consists of a bent L-shaped monopole extended from the ground and an L-shaped strip connected to the feed line. The bent L-shaped monopole with an L-shape strip coupled to excited the low and high band. By proper adjusting the parameters of the antenna, an antenna for WLAN application...
In this paper, we present a coupled-fed meandered loop antenna on a planar structure. The antenna is fabricated on the FR4 substrate of thickness of 1.6mm and permittivity of 4.4. The antenna with a total size of 30 mm × 13.75 mm × 1.6 mm is feed by a 50 Ohm mini-coaxial line. By using an L-shaped monopole connected on the coaxial line and the meander loop to generate multiple modes to form the required...
In this paper, a meandered monopole antenna with an extended back ground plane is proposed for WLAN USB dongle application. The meandered monopole excites a resonant mode at 2.4 GHz while the extended ground plane operates a higher mode for 5.15 GHz bands. A U-shaped strip is added to adjust the antenna's matching. From the simulated and measured return loss, the 10 dB operating bands cover the IEEE...
This paper proposes a small and compact MIMO antenna for USB dongle application. The proposed MIMO antenna consists of two PIFA antennas that operate the same frequency band at around 2.4 GHz for applying at WLAN band (2.4 to 2.484 GHz). An inverted-E element between the PIFAs and a meandered neutral line on the back side are used to increase isolation between the PIFAs, which is higher than 15 dB...
The band-rejected designs of the printed open slot antenna for wireless local area network (WLAN)/worldwide interoperability for microwave access (WiMAX) applications are investigated. First, the broadband characteristic (2.3 ~ 6uarr GHz) of open slot antenna design with small size is implemented and measured. Then, inserted a single strip on the broadband antenna is studied and investigated. By inserting...
