Enhanced Performance of Microstrip-fed Wide Slot Antenna using Periodic Gaps in Dielectric Substrate
The effects of a two-dimensional periodic dielectric substrate on the performance of a microstripfed wide slot antenna are investigated. The microstrip-feed and wide slot is placed on opposite sides of the periodic dielectric substrate. Method of Moment calculations using volume integral equations is employed to determine the effects of the substrate. It is proposed that by introducing a period...
متن کاملC-shaped slot loaded reconfigurable microstrip antenna
Introduction: Compared to broadband antennas, reconfigurable microstrip antennas offer the advantages of compact size, frequency selectivity and similar radiation pattern and gain for all designed frequency bands [1]. Several interesting approaches to electronic tunability for different antenna structures have been carried out. However, the tuning mechanisms used are complex and need extra matc...
متن کاملA Stacked Wideband Microstrip-Line-Fed Wide Slot Microstrip Patch Antenna
A simple, compact, slot loaded stacked wideband microstrip patch antenna is presented in this communication. The radiating element consists of a rectangular patch with a Tshaped slot and is fed by a 50 Ω microstrip line. The proposed antenna is simulated using IE3D software, 12.32 version of Zeland. The simulated results show that the antenna can exhibit wideband characteristics. The impedance ...
متن کاملA comparative Analysis of Nonresonant Microstrip Patch-Fed Dielectric Resonator Antenna and Proximity-Fed Annular Slot Antenna
This paper shows the comparative analysis of a cylindrical dielectric resonator antenna (CDRA) fed by nonresonant microstrip patch and a proximity-fed planar annular slot (PPAS) antenna. The antenna array having an antenna element for higher directive gain at the center frequency 9.04 GHz. The band-notch is detained by almost a half-wavelength split-ring parasitic element printed around the rad...
متن کاملA Novel Reconfigurable Hexagonal Slot Loaded Microstrip Antenna
The design of a compact, varactor controlled, electronically reconfigurable dual frequency microstrip antenna is presented in this paper. Dual frequency operation is realized by embedding a hexagonal slot with extended slot arms within a square patch. Varactor diodes integrated with the slot arms are used to tune the operating frequencies considerably, by applying reverse bias voltage. Tuning r...
