A substrate integrated magneto-electric (ME) dipole antenna with metasurface is proposed for the 5G/WiMAX/WLAN/X-Band MIMO applications. In order to provide the low profile characteristic, the radiated electric dipoles and the shorted wall are integrated in the multi-layer substrates at different altitudes. Unlike the conventional metasurface antenna, by introducing the ME dipole structure with modified...
The dual band MIMO antenna composed of inverted L antenna is proposed and numerically analyzed. The design frequency is 2.4 GHz to 2.5 GHz, 5.15 GHz to 5.35 GHz. Inverted L antenna is formed by the coplanar waveguide. The parasitic planar rectangular loop is placed above the of inverted L antenna. When the size of conducting plane is 51 mm by 48 mm, the S11 less than −10 dB is satisfied from 2.4 GHz...
In this paper a novel planar antenna is proposed for 5.2GHz band application. The area of designed antenna has been reduced by 52% in comparison to a conventional rectangular microstrip patch antenna. The antenna has three vertical stripes and one horizontal stripe. The length and width of these stripes are varied to tune the antenna for a certain operating frequency. The antenna is fed by using a...
In this paper, we propose a design method for a chassis MIMO antenna based on characteristic mode theory. Specifically, we provide a way to use a chassis with one axis of symmetry as a multiport MIMO antenna. The method utilizes a combination of characteristic mode and a mode-decoupling network, and suggests a way to design an inductive coupling element to excite specific characteristic modes while...
A low profile magneto-electric (ME) dipole antenna with wide H-plane and band-notch features is proposed for the fifth generation of mobile communication (5G) Multiple Input Multiple Output(MIMO) applications. The radiated electric dipoles are designed with two kinds of separated arc-shaped planes at different altitudes to provide the dual-band and wide H-plane characteristics. By employing the E-shaped...
This paper presents a monopole decagon fractal patch resonator with the defected ground plane for WLAN MIMO antenna. The fractal technique on the edge of the decagon patch is used for reducing the operating frequency of the antenna. Concurrently, the defected ground plane (DGP) with a rectangular shape can reduce the mutual coupling between the radiating patches due to the suppression of coupling...
In recent years, the MIMO (Multiple-Input Multiple-Output) technology, using multiple antennas, has been introduced in wireless terminals. If terminals are miniaturization, a strong mutual coupling caused by installing plural MIMO antenna closely is occurred. The coupling decreases radiation efficiency and channel capacity. Hence, the mutual coupling must be reduced. In previous studies, a decoupling...
A Tunable Inverted L Antenna (TILA) for Multiple Input Multiple Output (MIMO) mobile terminals is presented. Two ILAs with different lengths and varactor diodes are combined to enable bandwidth and resonance tunability at lower and upper bands respectively. The antenna 10dB bandwidth is tunable from 2250 MHz to 2700 MHz in the lower band and from 5000 MHz to 5800 MHz in the upper band. The realized...
A high isolation two-element MIMO antenna array is proposed by using embedded meta-material structure. The proposed meta-material is comprised of two layers at different level and the two layers are connected together by shorted pins. Five proposed meta-material cells are embedded in the FR-4 substrate, which is installed between the two antenna elements, to improve the isolation of the two-element...
A dual-band planar slot antenna is proposed for multiple-input-multiple-output (MIMO) array conformation, which achieves the 2.4GHz and 5.8GHz bands for wireless local area network (WLAN) application. The isolation between two antenna elements in the operating frequency bands is greater than 20dB by employing the decoupling slots structure. The envelope correlation coefficient (ECC) in the operation...
This paper presents a design of a wideband 6-port antenna array which can be used for MIMO communication systems. In the designed antenna that operates over the frequency band of 7–10GHz, four leaf-shaped notch antennas and two leaf-shaped monopole antennas are employed as radiating elements. Performance of the antenna is evaluated by the finite difference time domain (FDTD) analysis and measurement...
