Multiband Patch Antenna for Femtocell Application

Abstract EN

A microstrip patch antenna for multiple LTE (long term evaluation) frequency bands for femtocell application is proposed in this paper.

Distributed antenna solution (DAS) has been introduced in cellular network to achieve homogenous indoor coverage.

Femtocell is the latest extension to these solutions.

It is a smart solution to both coverage and capacity scales.

Femtocell operation in LTE band is occupied by higher frequency bands.

For multiband femtocell application, miniature antenna design is quite essential.

The antenna proposed here is composed of basic monopole structure with two parasitic elements at both sides of the active element.

A rectangular slot is introduced at the ground plane of the proposed antenna.

The antenna is designed using ElnoS HK light CCL substrate material of relative permittivity of 9.4, dielectric loss-tangent of 0.003 and thickness of 3 mm.

The S11 response of the antenna is shown to have a bandwidth of 1.01 GHz starting from 1.79 GHz to 2.8 GHz.

The characteristics of the antenna are analysed using Ansoft HFSS software.
