In this work, we study the performance of an antenna in microstrip technology designed especially for micro-cellular applications in a real context of mobile radio-telephony. To accomplish this, we designed an indoor cellular test network and implemented basic functions of the GSM protocol, by using Open Base Transceiver Station (OpenBTS): an open-source cellular infrastructure that uses Software Defined Radio (SDR) as a platform. Our proposed prototype is based on the Universal Software Radio Peripheral (USRP) device from National Instrument that is designed to operate in the sub-6 GHz band. Finally, a preliminary test of the Quality of Service (QoS) has been quarried-out by measuring the Receive Signal Strength Indicator (RSSI) between the deployed Base Station and the connected mobile stations (MS), and that for different scenarios and distances.

Interference management is the key point in the deployment of ultra-dense networks. Several techniques in physical and data-link layers have been discussed and proposed to provide lower power and better network capacity, while minimizing the cost and complexity of FemtoCell deployment. The applicability of an antenna with microstrip technology that employs multiple elements is developed here for coverage enhancement of FemtoCell network. The antenna proposed in this research has a size of 35 x 35 x 1.58 mm 3 , it is printed on a commercially available FR4 dielectric substrate and designed for the frequency band from 1.9 GHz to 3.5 GHz. The different results obtained of the studied antenna in the FemtoCell scenario are discussed.

A Compact microstrip antenna with rectangular slotted radiating element has been developed. Four slots have been introduced on the radiating element with the use of a partial ground plane and a wideband response has been obtained. The bandwidth of the proposed antenna is 1.7 GHz with a percentage bandwidth of 71%. A low-cost dielectric (FR4_EPOXY) has been considered in the development of the proposed antenna. The obtained frequency band is from 1.9 GHz to 3.6 GHz. To investigate the robustness of our modelled antenna the simulation process has been carried out using two different solvers (Finite Element Method and Finite Integration Technique). In addition, the designed antenna was realized and these results were compared with those of the simulation. The proposed antenna is suitable for many LTE bands {1, 3, 7… 38, 40} broadly deployed in European, South American, Asian, and African countries, Wi-Fi (2.4 GHz), and WiMAX technology (3.5 GHz).
