## Abstract In this article, a compact quad band monopole antenna is demonstrated. Asymmetric coplanar strip feeding is applied in the design in order to compact the size. The proposed antenna fabricated on a FR4 substrate has an overall size of 30β30 mm^2^. By integrating an invertβC slot and a mo
## Abstract A novel compact microstrip patch antenna is proposed for quad band, GSM850, GSM900, GPS (L1β1575 and L2β1227), and UMTSβ2110 application for cellular telephone system. Design is particularly unique since it supports the new generation mobile phone where multiband operation with minimum
## Abstract A novel internal monopole antenna suitable for applications in AMPS/GSM/DCS/PCS quadβband mobile phones is presented. The antenna comprises two orthogonal wideband monopole elements for operation at about 900 and 1850 MHz, covering the APMS/GSM (824β894/890β960 MHz) and DCS/PCS (1710β18
