(PDF) Miniaturized Wideband Aperture Coupled Microstrip … 1. Introduction. e microstrip patch antenna has been popularized because it. is being utilized in many modern communication systems for. its tremendous characteristics such as light weight, small size, low cost and easy fabrication [,]. Pozar []hasproposed. the aperture coupled microstrip... Ring-slot-coupled microstrip patch antenna for circular… The CP microstrip antenna isexcited by using a series microstrip-line-feed conguration through thecoupling of a ring slot in the ground.Thesimulated results are shown in Figure 2, together with those of across- slot-coupled microstrip antenna with the same patch size, inwhich the two slot... Harmonic-suppressed slot-coupled microstrip patch … A slot-coupled microstrip patch antenna was selected be- cause it provides wider bandwidth and more tuning parameters. Moreover, it can easily be integrated with the PA and provides suitable second and third harmonic load impedances for class-F operation. 2. ANTENNA DESIGN Figure 1 shows the...
The antenna of claim 9 wherein each of said cross slots comprises a horizontal slot, perpendicular to a vertical slot, and wherein said first microstrip feed network is associated with said vertical slot and said second microstrip feed …
Bandwidth enhancement of modified square fractal microstrip ... Narrow bandwidth is a major constraint of microstrip antennas. This paper illustrates the design of a gap coupled modified square fractal microstrip patch antenna which has been designed to overcome this limitation. The intended design has an impedance bandwidth of 85.42% around the resonant frequency of 1.844 GHz. Microstrip U-Slot Aperture Coupled Antenna for Wimax Application
Slot coupled microstrip patch antenna, shown in Figure 1.1.d is proposed by Pozar in 1985, [2]. It is also a noncontacting feed method. The structure consists of two dielectric layers, which may have different thickness and dielectric constants.
represents patch antenna impedance effects coupled through the ground plane slot, while the LC circuit represents ground plane slot resonant behavior and patch edge fringing field effects. Fig. 2 shows an equivalent circuit model for the aperture coupled patch antenna. Nominal antenna circuit model parameters are determined A Low Profile Multi-band U-shaped Aperture-coupled ... A Low Profile Multi-band U-shaped Aperture-coupled Microstrip Antenna with a Coil In this article, an L-shaped probe-fed, U-slot patch antenna with a coil element is studied. The L-shaped probe feed is used to enhance the impedance matching, which is necessary because of a low radiation resistance in the usable band. The coil contri...
