Further a slot loaded shorted patch antenna shows the dual frequency nature with the frequency ratio 1.7. The theoretical results are compared withIn this paper, two antenna geometries are analysed for dual band operation using the circuit theory concept. In first geometry, a notch with dimension (L n...
designed a slit-loaded notch-cut patch antenna based on investigations. The antenna patch is fed by coaxial feed. Meandering techniques and the new design are simulated in HFSS environment. Results show good return loss for new design. Index Terms: Patch antenna, Broadband, Compact, Meandering, Resonant Frequency. A Novel Concentric Annular-Ring Slot Dual-Band Circularly ... A simple structure concentric annular-ring slot dual-band circularly polarized (CP) microstrip antenna operating at ISM band (2.45 GHz) and 5G band (3.5 GHz) is proposed in this paper. The antenna achieves dual-band operation by digging two concentric annular-ring slots on the ground. And on the angular positions with 45 degrees inclined of each annular slot, two bent structures are loaded to ... DESIGN OF DUAL-BAND SLOTTED PATCH HYBRID COUPLERS BASED ON ... Design of dual-band slotted patch hybrid couplers 2411 the patch hybrid coupler. With the help of the four open-circuited shuntstubs [8,9], a dual-band hybrid patch coupler is then carried out, aiming to achieve two operating bands at UHF RFID band (915MHz) and GPS band (1575MHz) simultaneously. By following the design

The fabricated antennas were5 Geometry of dual offset microstrip feed line, left side, and bowtie aperture slot, right side, along with... Tri-Band Parallel Slots Loaded Circular Disk Patch … This paper presents the tri-band slot loaded patch antenna for mobile communication.The antenna consists of parallel slots loaded circular disk with defected ground structure antenna (DGS). The antenna without DGS, acts like wide band antenna and bandwidth is 34.45% (3.47 - 4.92 GHz)...
A planar UWB antenna with added GSM 1800/WMTS and UMTS bands is presented. A CPW-fed circular patch is used to obtain wideband characteristic covering the UWB range. A novel slot formed by merging the alternate sides of a hexagon with isosceles triangles is inserted in the patch to obtain dual-band operation with the lower band suitable for GSM 1800 operation.
