A design of compact MIMO antenna achieving the band of LTE 700 for fourth generation (4G) technology is proposed and studied. A very compact meandered monopole using the spaces on the front side and back side of the substrate is adopted for the design. The overall size of the design is 60 × 35 × 0.8 mm3, and the antenna portion of the antenna is 20 × 35 × 0.8 mm3, implemented on the FR4 substrate...
A coupled-fed monopole antenna with a multi-arm structure for GSM900/GSM1800 / DCS / PCS / UMTS / LTE2300 for USB dongle is presented. The monopole is fed by 50-ohm mini coaxial cable line. The two arms are on the front side and a meandered arm extended from the front side by via is on the back side. The multi-arms are coupled by an inverted L strip connected to feed point. The arms resonance of the...
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...
A compact dongle antenna achieving the band of LTE 700 for fourth-generation (4G) technology is proposed and studied.

This paper proposes a monopole type MIMO antenna for Long Tern Evolution 700 (LTE 700) band application. The overall dimensions of 70×30×1.6 mm3 of the proposed design are consisting of an antenna portion of 30×30×1.6 mm3 and system ground portion of 45×30×1.6 mm3. The antenna portion is composed of two identical monopole antennas located on FR4 substrate's top portion. The strips on the front side...
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...
