“…We propose to use a novel composite right/left-handed (CRLH) leaky-wave antenna (LWA) designed to provide dynamic radiation pattern diversity [9] [10]. The direction of the CRLH-LWA can be swept from backfire to endfire on-the-fly by changing the varactor voltages.…”

In this paper, we analyze a multiple-input multipleoutput (MIMO) wireless system with dynamic radiation pattern diversity provided by composite right/left-handed (CRLH) leaky-wave antennas (LWA's). The CRLH-LWA is electronically reconfigurable with real time continuously direction-steerable radiation pattern and adjustable beamwidth. Analysis shows that these features match the clustered nature of indoor channels, and thus can provide high capacity gain by increasing received power. Furthermore, in MIMO systems the fully steerable direction provided by the CRLH-LWA is able to decorrelate the MIMO channel and improve the channel capacity. The results presented in this paper demonstrate that this is a highly promising approach for future high throughput reliable MIMO systems.

“…In MIMO system, signal fading can be negated by using diversity transmitters and receivers. When antennas are separated in space (spatial diversity [3]) or support different polarization (polarization diversity [4]) or radiation patterns (pattern diversity [5]), communication channels with different fading profiles are created. The use of multi antenna structures, such as MIMO antennas, is one of the effective ways to enhance reliability and increase the channel capacity of MIMO systems [6][7][8].…”

This paper presents an SIW MIMO system antenna configuration. The paper is devoted to minimize the mutual coupling between antennas fed from different ports with the use of SIW structures. The paper discusses the system with and without introducing the SIW structure. The antennas are operating at 5GHz (Wi-Fi application). It contributes a mutual coupling reduction up to 16.6 dB. The antenna configuration is fabricated. It conducts a good agreement between the measured and simulated scattering coefficients. The antenna gain, and pattern are nearly unchanged for the different configurations.

“…Surface waves degrade the performance of UWB filters by causing spurious stop bands to appear [7]. Another problem in multilayer printed circuit boards is the excitation of resonance modes by simultaneous switching noise (SSN) leading to signal integrity problems and electromagnetic interference (EMI) [8][9][10]. The above discussed problems in microwave circuits can be minimized or overcome by the application of Electromagnetic Band Gap (EBG) structures.…”

In this paper, single and dual band EBG structures for wider bandwidth are proposed. In each of the discussed EBGs, a metallic patch of regular geometry is chosen for the unit element. The patch is further modified by cutting slots to get extra inductance and capacitance which results into lower cutoff frequency and larger bandwidth. The proposed EBG structures are compared with the standard mushroom type EBG with respect to surface wave attenuation. The-20 dB cutoff frequencies and bandwidths of the various EBGs are compared. The effect of unit element size, gap between unit elements and via diameter on the transmission response is presented. Among the discussed EBGs, the swastika type structure is compact, single band and has wider bandwidth. The square patch with a single disconnected loop type slot EBG and the Fractal EBG are dual band. While square patch is more compact, the fractal EBG has wider bandwidth. All the EBGs can be useful in the design of antenna and other microwave circuits.
