“…The impedance bandwidth of CRMSA is found to be 3.26%. The antenna resonates at four modes of frequencies f 1 , f 2 , f 3 , and f 4 with their respective impedance bandwidths BW 1 ¼ 2.9% (3.5-3.4 GHz), BW 2 ¼ 3 , and BW 4 are due to dual U slots and notches used on the patch. Figure 5 shows the variation of return loss versus frequency of DNDURMSA when U w ¼ 0.2 cm.…”

This article presents a novel design and development of dual‐notched U slots rectangular microstrip antenna for quad band tunable operation. The antenna operates between 3.45 and 8.75 GHz at four different frequency bands. The middle two bands merge into a single band by changing the width of U slot on the patch. This change will also effect in tuning the three bands on either side of the frequency spectrum without changing the nature of linearly polarized broadside radiation characteristics. The proposed antenna gives a peak gain of 1.52 dB. The experimental and simulated results are in good agreement with each other. A design concept of the antenna is given and experimental results are presented and discussed. This antenna may find applications in WLAN, WiMax, and the fourth generation mobile communication systems. © 2012 Wiley Periodicals, Inc.

“…The BW of CMSA (Circular Micro Strip Patch) is increased by cutting the slot at an appropriate position inside the patch and these slot cut CMSAs are optimized on substrates with thickness more than 0.09λo, the proximity feeding as well as L-probe feeding has been used [4,9,16]. For this basis, various efficient methods [5][6][7][8] were proposed to solve this problem, including the use of probe compensation [5], the U-slot [6], the L-probe feed [7], and use of the T-probe feed [8]. The approach using an Lshaped probe feed a rectangular patch was also found to yield an impedance bandwidth of 35% [7].…”

“…The parameters of the shifted cosine-squared function depend on the notch width for a given patch and substrate geometry. An analysis shows that the inset disturbs the transmission line or cavity model and augments the impedance variation with distance compared to a coaxial probe feed given a patch resonant length L and feed position x from the centre Ri=Re sin 4 (πx/L); 0<x<L/2 (3) is an approximate solution because at x = 0, the resistance remains finite [7]. Locating the feed from the equation using a radian angle measure:…”

Many applications of micro strip antenna are constricted by their innate narrow bandwidth. In this paper a survey on the different feeding technique, which are micro strip line feed, coaxial plane feed, proximity coupled feed and aperture couple feed, for wireless micro strip antenna is done. Micro strip line and coaxial probe feeds are contacting scheme, in which RF power directly to the radiating patch. Proximity and Aperture coupled feeds are non contacting schemes, in which electromagnetic field coupling is done to transfer power between the micro strip line and the radiating patch. In this paper, a new approach is projected to design inset feed micro strip antenna with slots in it to develop the antenna bandwidth. The input impedance matching method for antenna is predominantly vital for a feed technique. The design of slotted micro strip antenna on a substrate of thickness 11mm that give wideband features is based on embedding an inset look analogous proximity L shape feed to improve bandwidth. The Method of Moments (MOM) base IE3D software with the method of moment (MOM) ensemble has been used to in the circular patch performance comparison for the improvement of the impedance bandwidth and the power radiated with slots on the same physical dimensions.
