A novel approach for low mutual coupling and ultra-compact Two Port MIMO antenna development for UWB wireless application.

In this paper, a novel MIMO antenna operating in the UWB frequency band is presented. The proposed new antenna shape is derived from the conventional circular ring patch antenna having a partial ground plane. An array of three Quad-G Shaped Metamaterial structures was used between the antenna elements of the two-port MIMO antenna to expand the bandwidth in the lower frequency band of UWB application (below 5.

A shorting-pin based compact meander multiband printed monopole antenna.

The antenna presented in this work is based on a meandering monopole patch antenna with the incorporated shorting-pin technique for the realization of multiband antenna. The proposed antenna is printed on an FR4 with a footprint of at the lowest operating frequency. The antenna proposed demonstrated six resonances with suitable bandwidth as well as gain which make it suitable for WiMAX, LTE-A, aeronautical radio navigation, sub6GHz band for 5G, and WLAN applications.

Evaluation of adjacent channel interference from land-earth station in motion to 5G radio access network in the Ka-frequency band.

As the fifth-generation (5G) mobile communication service is expected to operate in one of the 11 candidate frequency bands of 24.25-27.5 GHz, compatibility and coexistence with other adjacent wireless applications must be evaluated.

Bio-inspired wideband antenna for wireless applications based on perturbation technique.

The evolution of advancement in communication technologies and ever-increasing demand by users for compact communication devices has necessitated a shift in the design approach to achieve antenna structures that are compact and robust. Owing to the diverse communication requirements, antenna systems operating across wide bands have become a necessity. An antenna that is capable of working effectively in several bands is called wideband antenna.

Frequency re-use distance calculation in cellular systems based on Monte-Carlo simulation.

Radio spectrum's sharing guideline is an essential component of spectrum utilization process. Since there is no insightful interference avoidance method in a radio system, the careful selection of sharing conditions is the only means for achieving successful co-existence and optimal spectrum usage in the radio system. Spectrum sharing rule can be obtained by an analytical method or statistical method.
