This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement. An I-shaped microstrip line is used to excite the square slot. Design and Simulation of an Improved Bandwidth V-Slotted ... In this paper, we design and simulation of an improved bandwidth V-slotted Patch Antenna for WiMAX which is operated for WLAN applications is used as a based model. It is proposed that by the use of the corner truncated patch scheme we can widen the operational bandwidth of the antenna and can achieve Compact Open-Slot Antenna With Bandwidth Enhancement ... Abstract: A compact open-slot antenna for bandwidth enhancement is presented. Multiple resonances are generated by using an asymmetrical rectangular patch with the U-shaped open-slot structure. Two bevels are cut on the patch to improve the impedance matching. Design of a novel bandwidth-enhanced double-slot TSA and ... The paper proposed a double-slot Vivaldi antenna, the impedance bandwidth has been significantly improved, the fractional bandwidth of the antenna reached 142%. But the bandwidth of the gain more than 10 dB is only from 5 GHz to 15 GHz. In this paper, a modified tapered slot antenna with double-slot structure, is proposed.

Slot antenna Slot antenna with FSS (simulated).A second order, band pass frequency selective surface with large bandwidth combined with a wideband slot an-tenna has been studied and demonstrated successfully. Slotted UWB Antenna for Bandwidth and Gain Enhancement Capability of operating over wide frequency bands and good radiation characteristics lead to choosing a rectangular radiation patch as a basic structure of the slot antenna. Modifications have been applied to the radiation patch to manage the current distribution in order to achieve a wide bandwidth. Implementation of rectangular slit-inserted ultra-wideband…
A novel design of broadband patch antenna is presented in this paper. The broadband property of the proposed antenna is achieved by choosing a proper selection of dimensions and positions of slot and notch on the radiating patch. The bandwidth of the proposed antenna is found to be 30.5% with operating frequency band from 1.56 GHz to 2.12 GHz.

This technology demands for antennas with wide bandwidth and good isolation characteristics. There are various techniques proposed for improving the bandwidth of microstrip antennas. In [1], authors achieved considerable amount of bandwidth by employing slots and annular ring in the ground plane. Design and Simulation of an Improved Bandwidth V-Slotted Patch ... microstrip patch antenna is possible to increase the bandwidth [2]. But this technique arise has several problems of antennas feeding technique [2]. There is an effective method is corner truncated scheme is used to enhance the bandwidth for ultra-wideband (UWB) applications [3]. A monopolar V-shaped slot patch antenna has been Improved Radiation Performance of Low Profile Printed Slot ... Abstract: In this paper, a novel design of low profile printed slot antenna using wideband artificial magnetic conductor (AMC) is presented with improved radiation performance. For this purpose, the radiating slots with three unequal arms fed by coplanar waveguide are employed for broadening the impedance bandwidth with three resonances.
