نویسندگان
چکیده
The purpose of this paper is to design and fabrication of an annular ring slot patch antenna with short stub (ARSPA) for mobile applications Digital Cellular System (DCS) (1.711.88) GHz, Personal Cellular System (PCS) (1.85 -1.99) GHz, and Universal Mobile Telecommunications System (UMTS) (1.71-2.17) GHz. Return loss and bandwidth are studied with respect to short stub location. By using short stub the bandwidth is enhanced comparing with that of without short stub. The designed antenna simulated by the software Computer Simulation Technology microwave studio (CST), through which the radiation patterns, VSWR, return loss, and gain were generated. The proposed antenna has compact size (60*60*1.6) mm. We have been good results between simulated and fabricated antenna.

Integrated Compact Circular Polarization Annular Ring Slot Antenna Design for Rfid Reader
An integrated compact circular-polarized annular ring slot antenna is proposed in this paper. It consists of an annular ring slot radiator and a hybrid patch coupler. The hybrid patch coupler is integrated with the annular ring slot antenna to radiate the circularpolarized wave, while size of the antenna remains the same. Both the impedance bandwidth and axial ratio bandwidth of the proposed de...
