A Low-Frequency Annular-Slot Antenna James R. W ait The radiation characteristics of an annular slot cut in an ideally conducting ground plane are discussed. The voltage impressed between the concentric edges is assumed to be constant around the slot. The annular slot is backed by a hemispherical cavity which has Aperture Coupled Microstrip Antenna Design and Analysis Aperture Coupled Microstrip Antenna Design and Analysis Michael Paul Civerolo A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software [1]. This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation Design of an efficient miniaturized UHF planar antenna ... Design of an Efficient Miniaturized UHF Planar Antenna Kamal Sarabandi, Fellow, IEEE, and Reza Azadegan, Student Member, IEEE Abstract— In this paper, the design aspects and the measured results of a novel miniaturized planar antenna are described.

A New Compact Slot Antenna for Dual-band WLAN Appli cations 29 relative permittivity of 4.6. Table 1 summarizes the detailed dimensions of the antenna parameters as labeled in Figure 1.
Further it can be noted that, DNSMSA shows virtual size reduction of about 13.01% which indicates the compactness of the antenna. Also, the frequency ratio f2/f1 of the antenna is found to be 1.70 which shows the flexibility in the design of dual and triple frequency antennas. Design of Dual-Band Microstrip Antenna with U-shaped slot resonant frequency. Design process For designing of a rectangular microstrip patch antenna with U-shaped slot as shown in Figure1 (a), we have to select the resonant frequencies and a dielectric medium for which antenna is to be designed. The side view of the microstrip patch antenna with coaxial feeding method is explained in Figure1 (b). Chapter 5 Impedance of Slot Antennas 5.1 Introduction narrow slot approximation is reasonably good as shown in Figure 5.3. Note that the series impedance of the slot varies slowly with respect to frequency and that the reactive part is fairly flat and is capacitive above resonance. When additional layers are added, (layer 2 is εrÊ=Ê2.4 and layer 3 is εrÊ=Ê13) where each layer is nominally Chapter 8 Slot Antennas - eetrend.com A slot-antenna design will often require that the slot be cut in something other than an extended flat sheet surface. Whatever the surface, the electric field will be normal every-where except in the region of the slot. The field due to the electric currents on this metal surface can be deduced from the exciting magnetic currents2 in the slot ...
