“…Over the past years, dual ports reader antenna designs have received considerable attention. Among dual polarized antenna designs, aperture coupled microstrip patch antenna are the most suitable candidates for RFID application [8][9][10][11][12][13][14][15][16][17]. Aperture coupling is preferred to other feeding mechanisms of microstrip patch antenna due to its greater design flexibility, easier fabrication and lower cost.…”

“…As, the antenna is to be used with a handheld RFID reader, the size of the antenna in general should be around 100 mm length and width, and around 10 mm in thickness [3]. Therefore, most of open literatures including [8][9][10][11][12][13][14][15][16][17] described reader antennas with dual ports are comparable large to be mounted onto a handheld RFID reader, however they are suitable for stationary readers.…”

A compact dual ports antenna with high isolation is proposed for handheld radio frequency identification (RFID) reader, which is rarely reported in open literatures. Different with conventional handheld RFID reader antenna with single port, the proposed antenna transmits and receives signal separately. The proposed antenna operating with full duplex mode can enhance effectively sensitivity of reader, as the strong transmitting signal of reader with single port is usually highly coupled with weak receiving backscatter signal of tag. The antenna utilizes aperture coupled patch structure that occupies less volume and provides further space‐saving efficiency. The height of the proposed antenna is only 5.1 mm and the volume of that is 80 ×80 × 5.1 mm3, which is easy to integrate in handheld RFID readers. The antenna uses four symmetric coupling apertures to excite two orthogonal modes for dual polarized operation. High isolation of around −35 dB is obtained by proper arrangement of the length and position of the coupling apertures. The maximum measured return loss is −39 dB at 2.4 GHz and isolation is −47 dB at 2.4 GHz. The antenna is suitable for applications in handheld RFID readers. © 2015 Wiley Periodicals, Inc.

This article presents a novel dual-polarization textile antenna (DPTA) for Global Positioning System applications. In this design, four sector radiating elements are centrally fed by a coaxial probe. A novel antenna structure is successfully achieved by integrating electronic components into a wearable textile antenna. Silver loaded epoxy adhesive is used in embedding four PIN diode switches on Shiel-dIt super textile of the proposed antenna. The activation of certain PIN diode switches configuration determines the polarization of DPTA. Dimension-wise, this antenna is compact and small where it consists of 40-mm radius .The proposed DPTA design successfully generated dualpolarization omnidirectional radiation pattern with maximum gain 1.81 dB at angle of 0 /360 , 90 , 180 , and 270 . Its small size, flexible, and wearable features enables this DPTA to be easily integrated onto safety jacket and rain coat for tracking, search, and rescue applications.
