Abstract-This paper presents a study of the effects of line width on the resonance frequency and bandwidth of a microstrip squarering antenna at its primary resonance frequency. Although such ring antennas operating in TM 11 mode are smaller than regular patch antennas, they are not explored much as they are considered to have poor bandwidth and efficiency at this mode. We have used a transmission line model to study their input characteristics and found that a non-uniform width ring antenna has significantly better (nearly double) bandwidth and radiation efficiency than a uniform width square ring antenna. Extensive simulations were done and a prototype non-uniform width square ring antenna is fabricated and tested to verify these results.

The main focus of this paper is to study and analyze how the performance of rectangular U slot antenna is affected by the variation of U slot position. The work presented herein is a simulation based study. Experimentally, it has been revealed that variations in parameters such as the width and length of the U-slot, height and size of the patch, probe size and location as well as substrate permittivity can dramatically change the antenna's behavior. Till date, no analytical methods have been developed that accurately relate the complex relationships between the antenna dimensions and individuality. This paper describes the behavior of antenna with change of U slot position. A numerical solution is obtained by varying the various positions of U slot along all the axis and the effect of U slot position on various antenna output parameters is analyzed.

“…A broadband microstrip antenna is very useful in the commercial applications such as wireless local area network (WLAN), and Bluetooth personal network. Therefore, various designs have been proposed to improve their bandwidth including different shapes of patch [1,2], stacked patch [3,4] and shorted patch antenna [5]. Recently several interesting designs of the slot antenna with different geometric configurations for the bandwidth enhancement and the size reduction have been widely studied [6,7].…”

Abstract-In this paper, a bandwidth enhancement technique of asymmetrical slot antenna with two different excitation methods is presented. One method of excitation is the microstrip line feed, and the other is the coplanar waveguide feed. The rectangular slot excited by microstrip line feed gives an impedance bandwidth of 14.76% (|S 11 | < −10 dB). When the rectangular slot is excited by a coplanar waveguide (CPW), it gives an impedance bandwidth of 26.61%. Both impedance and radiation characteristics of these antennas are studied.
