Microstrip patch antennas are widely used in various wireless applications such as Wireless local area network (WLAN). WLAN is capable of providing maximum data transfer rate of 600 Mbps. The proposed antenna design has a slotted H-shaped patch and dumbbell (H) shaped Defected Ground Structure (DGS) on Flame Retardant-4 (FR-4) substrate with the microstrip feeding technique which radiates at 2.4GHz...
A reconfigurable antenna covering three bands of frequencies WLAN, WiMAX, LTE Communication bands is designed. This antenna operates between these bands with the activation of two switches. The proposed antenna has small size and low profile design and occupies a volume of 18×20×0.5 mm3. The results include analysis of return loss and peak gain of antenna. High Frequency Structure Simulator (HFSS)...
In this paper, the design and simulation study of a dual-band inset-fed log-periodic microstrip patch antenna is presented for next generation Wireless LANs. The microstrip antennas are preferred for applications where small size antennas are required which leads to the drawback like narrow bandwidth. To overcome this shortcoming in microstrip antennas, several design techniques are proposed one of...
This paper presents a new design of a multi-band microstrip-patch antenna with a proximity coupled feed for operating at Bluetooth, Wi-Fi, ISM, WiMax and WLAN Bands. The proposed antenna consists of a V-shape patch with a rectangular shape strip in middle of it and a defected ground plane. The band around WiMax and WLAN application are achieved by adding rectangular strip in middle of patch. A defected...
This paper presents wideband E shaped MSA for high speed WLANs operating in the 5-6 GHz range. By using the slotted edge and changing the position of the probe bandwidth equal to 14.90% is achieved. The antenna is fed by coaxial probe feeding technique. The designed antenna operates in the WLAN frequency band i.e. 5.15 GHz -- 5.35 GHz and 5.725 GHz -- 5.825 GHz which is suitable for a tourist or traveler...
In this paper, a compact gourd-shaped dual-band antenna is presented. The proposed antenna mainly consists of two connected circular discs and a slotted stub extending from the upper circular disc. The designed antenna can support 3.5/5.5GHz WiMAX and 5.8GHz WLAN simultaneously. The simulated -10 dB return loss bandwidth of this dual-band antenna is from 3.0 to 4.0GHz and 5.4 to 6.4GHz. The antenna...
This paper describes a novel dual-band patch antenna on organic magnetic substrate for wireless local area networks (WLAN) wireless communication (at 2.4 and 5 GHz). The dual-band operation is obtained by embedding a pair of L-shaped slots. The magnetic material is adopted because the substrate can reduce the size of antenna 40%, comparing with rectangular microstrip antennas on normal dielectric...
A miniaturized planar ultra wideband (UWB) monopole antenna is presented in this paper. By etching a C-shaped slot in the radiating patch, a band-rejected filtering properties in the WLAN band is achieved. By changing the thickness of the C-shaped slot, the notched frequency changes. An equation is introduced to calculate the thickness of the slot corresponding to a required notched frequency. The...
The evolution of antenna technology for man-machine interface has taken quantum leaps in utilizing textile materials as antenna substrates. In future this will allow complete freedom to develop body-worn antenna systems embedded in so- called "smart clothes". Smart clothes will emerge in various sports outfits, emergency workers' outfits, military, medical, space applications and so on....
This paper presents a low-cost ultra-wideband microstrip antenna for wireless communications. Printed on a 4cm × 5cm × 1.6mm FR4-epoxy substrate, the antenna features a microstrip feed line with two 45-degree bends and a tapered section for size reduction and matching, respectively. The ground plane is partial and comprises a rectangular part and a semi-circular part, where two identical rectangular...
Communication terminals for WLAN and similar systems require omni-directional antennas which can be used as a single radiator or in array and MIMO arrangements. The paper proposes to use low-profile top-loaded monopole and top-loaded folded monopole radiators and the integration into planar circuits where the radiators are directly fed (without a launcher) by microstrip line. The design and performance...
The design of a novel dual-monopole antenna that demonstrates dual-band operation and omni-directional radiation patterns in both frequencies of operation is discussed in this paper. The bands of operation exceed the officially designated bands for both the IEEE 802.11a and IEEE 802.11b wireless communication protocols. The effect of the geometry characteristics on the return loss and the radiation...
