Design of a Broadband Stacked Rectangular MPA with Shorting Pins for GSM-Family and Other Cellular Applications

This paper presents a design of a single coaxial-feed stacked rectangular microstrip patch antenna (MPA) with shorting pins. The proposed MPA design is based on the multilayer structure technique, and the cellular hand-set plastic cover is put as a one layer of the MPA structure layers. A finite- element based solver has been used to achieve the proposed design. This stacked MPA can cover most of the GSM-family standards including E-GSM 900 (880-960 MHz), GSM 1800/DCS (1710-1880 MHz) , GSM 1900/PCS (1850-1975 MHz), UMTS (1885-2200 MHz), the global new 3-G IMT-2000 (2500-2690 MHz), and WLAN+Bluetooth applications (2400 MHz) with return loss L
