Defense Technical Information Center Compilation Part Notice A NOVEL APPROACH FOR BANDWIDTH ENHANCEMENT OF SLOT ANTENNAS Nader Behdad, and Kamal Sarabandi Department of Electrical Engineering and Computer Science University of Michigan, Ann Arbor, MI, 48109-2122 behdad@eecs.umich.edu, saraband@eecs.umich.edu Abstract: A novel approach is presented to improve the bandwidth of slot antennas. Vol. 4, Issue 1, January 2015 A Survey on Patch Antenna Recently, those bandwidth enhancement systems pointed out above were engaged to the short-circuited patch antennas to comprehend a wide impedance bandwidth [12-14]. An impedance bandwidth of 30% was achieved using two stacked shorted patches [12]. However, the stacked geometry may augment the complexity of the antenna. A NOVEL SLOT FOR ENHANCING THE IMPEDANCE … Several promising techniques are available in the literature for the enhancement of impedance bandwidth of MSAs such as use of stacked antenna [1], additional resonators [2], aperture coupling method [3], etc. But, these methods are efiective for the antenna with a thick substrate.

A Novel Approach for Bandwidth Enhancement of Slot Antennas A novel approach is presented to improve the bandwidth of slot antennas. The technique is based on manipulating the field distribution along an ordinary resonant slot structure using the feed line and creating a dual resonance behavior. Hence without changing the length of the antenna its bandwidth is increased by more than 200% relative to a narrow slot. DTIC ADP017236: A Novel Approach for Bandwidth Enhancement A novel approach is presented to improve the bandwidth of slot antennas. The technique is based on manipulating the field distribution along an ordinary resonant slot structure using the feed line and creating a dual resonance behavior. A novel approach for bandwidth enhancement of SIW-based In this paper, a new approach for bandwidth enhancement of slot array antenna is presented. The idea is to use fractal-shaped slots to increase bandwidth for return loss less than -10dB up to 12.1

In this paper a broadband unidirectional planar microstrip antenna is presented. The proposed geometry consists of rectangular loop having two gaps and metallic strips. Although, the rectangular loop in the geometry introduces a good directionality but offers a narrow bandwidth. Printed Wide-Slot Antenna Design with Bandwidth and Gain ...
