In this paper, the analysis of reconfigurable frequency textile antenna in bending conditions is presented. The antenna consists of a truncated rectangular patch and slotted ground plane made by ShieldIt Super. Felt fabric is used as an antenna substrate. The proposed antenna is capable to reconfigure at seven different states frequencies by using three PIN diodes. The Circular Polarization (CP) is achieved at the GPS operating frequency. Meanwhile, the proposed antenna operates as a Linear Polarization (LP) at high operating frequencies. The performances of antenna in bending conditions is analyze since the textile antenna usually attached on the body will easily bend due to the human body structures. Details of the simulation results for antenna in bending condition are discussed.

This paper presents a reconfigurable beam dielectric resonator antenna (DRA) at 2.4 GHz by adopting the yagi-uda concept. Rectangular dielectric resonator antenna (RDRA) have been chosen as the radiator and fed by slot aperture. The antenna is designed in Taconic substrate with permittivity of 2.2. Firstly, a single antenna with two different modes is designed and investigated. The best performance mode in term of gain is then used to design the single driven RDRA with two parasitic RDRA, connected with the four RF pin diode BAR50-02V as switch. The analysis of the gap between driven and parasitic element is investigated. Four different types of switch configuration have been carried out to identify the performance of antenna in different cases. Depending on the switch configurations, the designed antenna can achieved highest gain of 7.386 dB and have steering angle capability at-42°, 42°,-54° and 54°.

Radiation pattern reconfigurable MIMO Antenna with practical DC bias network

2022-01-01 , Jaya Bharath A/L Gopalakrishnan , Thennarasan A/L Sabapathy , Muzammil Jusoh , Hasliza A Rahim @ Samsuddin , Muhammad Ramlee Kamarudin , Soh Ping Jack

This paper presents a radiation pattern reconfigurable (RPR) based multiple-input multiple-output (MIMO) antenna. The proposed antenna operates at 3.5 GHz for all switching conditions with S21 results of less than -20 dB. This work specifically focuses on implementing a practical DC bias network for the previously proposed RPR-MIMO antenna. The DC bias design is crucial where the tilt angle is slightly affected. This could be due to the isolation loss and insertion loss provided by the actual switch; and the DC bias lines that were constructed using a few DC blocking capacitors and RF chokes. Finally, a comprehensive analysis was carried out to examine the beam steering performance of the antenna when implemented with the DC bias network.

Switchable Beam Antenna with Five Planar Element using PIN Diode in Elevation Plane

2020-09-28 , Adan, Fuad Hassan , Muzammil Jusoh , Alaydrus M. , Mohamed Nasrun Osman , Thennarasan Sabapathy , Awal M.R. , Alomainy A. , Kamarudin M.R. , Mohd Najib Mohd Yasin , Hasliza A Rahim @ Samsuddin , Majid H.A.

This work focuses on the switchable beam parasitic patch antenna for the point to point communication system. This concept gives more flexibility due to their ability to modify the radiation and providing multiple functionalities. This work focuses on two points directly to minimize the number of PIN Diode and to maximize its reconfiguration capabilities. First, the concept of two parasitic element is addressed. The mutual coupling effect between both driven and parasitic has manage to steer the beam to-28{\mathrm{o}}, \ 0{\mathrm{o}} and +28o different angles in a single layer. The design consists of four parasitic elements with full ground and four pin diode switch HPND-4005, five different directions have been reached which are-450,-30{\mathrm{o}}, \ 0{\mathrm{o}}+30{\mathrm{o}} and +450. The parasitic patch antenna has achieved high gain of 8. 92dBi at 5.8 GHz with the beam ability to steer unti145o for both side of the parasitic element.
