broadband slim internal antenna for wireless and satellite phone communications

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, 1525-1661 mhz) 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 portable devices. the antenna has a dimension of approximately 0.43λ×0.02λ×0.008λ while achieving a gain and an efficiency of 2.4 db and 95%, respectively. using a defected ground plane the antenna impedance 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. good agreement between the simulation and measurement results is obtained.

Broadband Slim Internal Antenna for Wireless and Satellite Phone Communications

In this paper, a new broadband slim rectangular microstrip patch 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, 16161626.5 MHz; Inmarsat and Ligado, 15251646.5 MHz and Thuraya, 15251661 MHz) applications is proposed. The antenna is comprised of a slim rectangular patch, a shorting pin, a meanderline structure, and a defected ground plane. Its striplike shape helps to be easily mounted inside the portable devices. The antenna has a dimension of approximately 0.43λ×0.02λ×0.008λ while achieving a gain and an efficiency of 2.4 dB and 95%, respectively. Using a defected ground plane the antenna impedance bandwidth (|S11|<−6 dB) of 32.6% from 1.44 to 2 GHz is observed. In order to validate simulation results, a prototype of the proposed printed antenna is fabricated and tested. Good agreement between the simulation and measurement results are obtained.
