چکیده
Objectives: To investigate the effect of comb-like slot dimensions on dualband microstrip antenna performance parameters. Methods: Alternate comblike slots are placed patch and varied to observe The design is simulated in Mentor Graphics software package. results verified with Finite Difference Time Domain (FDTD) analysis MATLAB. measured Vector Network Analyzer (VNA) good agreement results. Findings: A dual-band operation resonating at 2.25 GHz 3.5 observed. return loss -30.23 dB -33.3 noticed. gain directivity 4.11 dBi 6.2 dBi; whereas, it 4 6.8 respectively. It observed that width significantly influences impedance matching. alternate arrangement increases electrical length improves Return Loss (S11). Novelty: Enhancement S11 characteristics without significant shift frequency by felicitous placements novelty proposed work. Keywords: Slotted Antenna; Dual Band; FDTD; UPML; (S11)

Dual Band Slotted Patch Antenna for On/Off-body Communication
Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...
متن کاملDesign of Different Slotted Microstrip Patch Antenna for Rfid Applications
A compact cross, circular and square shaped slotted microstrip patch antennas are designed for circularly polarized (CP) radiation. Asymmetric, cross-shaped slot is embedded along one of the diagonal axes of the square patch for CP radiation and antenna size reduction. The designed antenna is contrived by using RT-Durid 5880 substrate . The design simulation and optimization is done by ADS soft...
متن کاملCompact dual band slotted patch antenna for wireless systems
This paper presents the study on a slot-etched rectangular patch antenna directly fed by the 50 Ω semi miniature A-type (SMA) co-axial connector for wireless systems. The dual frequency behaviour by etching the slots on plane patch surface is studied experimentally. The proposed patch antenna has also achieved 28% compactness with a gain of 9.74 dB. Other antenna parameters such as antenna inpu...

متن کاملDual-Band Annular-Ring Microstrip Patch Antenna for Satellite Applications
A dual-band circularly polarized antenna fed by four apertures that covers the bands of GPS, Galileo, is introduced. The ARSAs designed using FR4 substrates in the L and S bands have 3-dB axial-ratio bandwidths (ARBWs) of as large as 37% and 52%, respectively, whereas the one using an RT5880 substrate in the L band, 61%. In these 3-dB axial-ratio bands, impedance matching with VSWR<=1.8 is also...
