In this paper, design of a filtenna with reconfigurable band-rejection for Ultra Wideband (UWB) communication applications is presented. The proposed antenna is a simple circular radiation patch structure with half ground plane. The band-rejection characteristics is achieved by integrating straight open stub in the feed line to overcome the interference Wireless Local Area Network (WLAN) that operated...
The design of single band Planar Inverted F Antenna (PIFA) for Long Term Evolution (LTE) mobile application is presented in this paper. The antenna consists of a rectangular planar element located above the Flame Retardant 4 (FR4) dielectric substrate. The ground plane is on the bottom side of the substrate. Total dimension of PIFA is 21.72 mm × 18.5 mm × 4mm and has been optimized to cover the LTE...
This paper presents a novel of a Frequency Reconfigurable Stacked Patch Microstrip Antenna (FRSPMA) integrated with radio frequency (RF) switch. It consists of three substrate layers where all layers uses RT-Rogers 5880 with a thickness of h1=0.787 mm. A 0.3mm (h2) thick air gap is filled between the stacked radiating patch (layer 1 and layer 2) and the feedline substrate to enhance the gain performances,...
Log periodic antenna (LPA) has been designed using rectangular microstrip patches with inset feed using five elements. The antenna elements and feeding networks is designed using Computer Simulation Technology (CST) Microwave Environment software. The manipulative variable is the spacing between the patches. The simulated and measured results are compared and it is observed that the value of return...
A novel structure of Reconfigurable Planar Antenna Array (RPAA) added with a microwave absorber is designed. This antenna is consists of two elements structure, which are the 16-element microstrip rectangular patch antenna structures (top structure) and the separated feed line structure (bottom structure). The unique property of this antenna design is that instead of fabricating all together in the...
A novel structure of Reconfigurable Orthogonal Antenna Array (ROAA) was constructed as a box structure which includes four verticals of the Reconfigurable Planar Antenna Array (RPAA) at 5.8GHz is presented. The main objective of this work is to design and analyze the ROAA with its active feeding network (based on PIN diode switches) to steer beam over 360°. The integration of PIN diode switches with...
A double elements micro-strip antenna with mushroom-like electromagnetic band gap (EBG) inserted between elements have been investigated. The performances of the antenna before and after the EBG are inserted between the micro-strip patches are analyzed. FR4 substrate with dielectric constant of 4.7 and 1.6mm thickness was simulated at operating frequency of 5.8GHz. The results shown that the performance...
A novel structure of Reconfigurable Orthogonal Antenna Array (ROAA) constructed with separated feeding network by air gap technique is introduced in this paper. In contrast to conventional antennas producing fixed directional radiation patterns, the ROAA studied here is able to scan the beam over 360° in the horizontal plane. The structures are consists of four Reconfigurable Planar Antenna Arrays...
Localization and responded accordingly are the most challenging and important issues in reconfigurable microstrip antenna (RMA). Hence, the challenges of combining Radio Frequency Identification (RFID) technology into the RMA are outlined. Integrating RFID into RMA is very important in wireless communication systems since the technologies have the ability to predict exact location of the users. In...
