Abstract:

A new broadband slim microstrip antenna with a narrow ground plane for GPS (1575.42 MHz),Glonass (1600 MHz), GSM (1800 MHz), LTE (1700 MHz), DAB (1452 MHz) and satellite phone(Iridium, 1616-1626.5 MHz; Inmarsat and Ligado, 1525-1646.5 MHz and Thuraya, 1525-1661MHz) applications is proposed. The antenna is comprised of a slim rectangular patch, a shorting pin,and a meander-line structure. Its strip-like shape helps to be easily mounted inside the portabledevices. The antenna has a dimension of approximately 0.43λ×0.02λ×0.008λ while achieving a gainand an efficiency of 2.4 dB and 95%, respectively. Using a defected ground plane the antennaimpedance bandwidth (|S11|<−6 dB) of 32.6% from 1.44 to 2 GHz is observed. In order to validatesimulation results, a prototype of the proposed printed antenna is fabricated and tested. Goodagreement between the simulation and measurement results is obtained.
