Non-Resonant Slotted Waveguide Antenna Design Method 32 High Frequency Electronics High Frequency Design ANTENNA DESIGN I n this paper a non-resonant slotted waveguide antenna design method is present-ed. The internal and external mutual coupling between adjacent radiat-ing slots is considered in the described meth-od. In order to confirm the usefulness of this method, a non-resonant waveguide array Design of dual-band and high gain waveguide slot antenna ... A new kind of dual-band and high gain waveguide slot antenna is designed in this paper. By combining a folded plate and a double-layer metal structure with four apertures on its top floor, the proposed antenna has a dual-band characteristic and its gain reaches up to 11.9 dB with only 35 degrees (HPBW) of E-plane at 12.7 GHz and 12.1 dB with 39 degrees at 15.0 GHz. TAPERED MEANDER SLOT AND COPLANAR SLOT ANTENNA FOR DUAL AND ... A compact meander-type slot antenna with 56% size reduction has been reported in [3] in which non-uniform slot line widths give rise to lower operating frequency of the antenna. In this paper we show that a dual-frequency operation is achieved by using a tapered meander slot antenna with a short-ended microstrip line feed. The

This makes the design of dual-frequency imide substrate with an embedded twin strip slot structure and multi-frequency solar slot antennas difficult, as com- to generate dual resonant frequencies.

Non-Resonant Slotted Waveguide Antenna Design Method High Frequency Design ANTENNA DESIGN where C 0 is a phase difference of currents feeding adja-cent slots, while d is a physical distance between these slots. One use for these antennas is in a thin array for radio-location devices. It is desirable in these applications to transmit and receive energy to and from a narrow sector of a free space. CIRCULAR MICROSTRIP SLOT ANTENNA FOR DUAL- FREQUENCY RFID ... favorable to design a single antenna which operates on both frequency bands. A variety of dual-band slot loaded antennas have been reported in [26{28]. The dual-frequency characteristics have been demonstrated owing to a pair of slot is placed close to the radiating edges. However, the proposed antenna utilizes probe feeding that results in narrow Dual-frequency slot-loaded rectangular microstrip antenna In thi s sllldy, dual-frequency slot-loaded rectangular microstrip antennas were designed, fabricated and evaluated. The design consists of rectangular patch microstrip antenna loaded with a pair of narrow slots parallel and close to the radiating edges on the patch, which is feel by centre-fed microstripline feed . Slot Antenna

Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surface they are to be mounted on, and have radiation patterns that are roughly omnidirectional (similar to a linear wire antenna, as we'll see). The polarization of the slot antenna is linear.

Wideband rectangular slot antenna for personal wireless ... Antenna designs were achieved for wideband operation by the use of a coplanar patch-slot antenna, fed by a coplanar waveguide. This design is easily tuned to operate at 2.45 and 5.75 GHz, with wide bandwidth for wireless systems. The oper- ating frequency is controlled by modifying the patch dimensions.
