Design of Asymmetric Slot Antenna with Meandered Narrow Rectangular Slit for Dual Band Applications Raj Kumar1, *, Praveen V. Naidu2, and Vivek Kamble3 Abstract|A compact, coplanar waveguide (CPW) fed asymmetric slot antenna with dual operating bands is proposed. The slot is modifled rectangular in shape and asymmetrically cut in the ground plane. IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 53, NO. 1,... A. Antenna Design A resonant narrow slot antenna is equivalent to a magnetic dipole, and at its first resonant frequency it has an equivalent length of ( is the guided wavelength in the slot). If the slot antenna is fed near an edge by a microstrip line and the slot width is properly chosen, at a frequency above the first slot res- 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 Radar Basics - Slot Antennas A single narrow slot radiator can also work on frequencies ±5 … ±10% besides its resonance frequency. For array antennas, this is not possible so easily. Such a group antenna is fixed strongly to a single frequency, which is determined by the spacing of exactly λ g , and for which the antenna has been optimized.
The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.
Design And Analysis Of Compact U Slot Microstrip Patch ... The work started with basic rectangle antenna with resonant frequency 2. 43GHz and bandwidth of 68MHZ, then the same antenna was converted to U -slot patch antenna which resulted into lower shift in frequency of operation at 2. 10GHz. This result shows an area reduction of antenna. The size of this slot antenna is lower than that of Design of Narrow Slotted Rectangular Microstrip Antenna This paper presents a design of narrow slotted rectangular microstrip antenna and experimentally studied on Ansoft Designer v-2.2.0 software. This design technology is achieved by cutting all three slots in microstrip antenna and placing a single coaxial feed.

To better explain the antenna design, Fig. 2 shows four evolution stages of the antenna. Initially, a square slot antenna with two CPW-fed ports are depicted as shown in Ant.1 of Fig. 2. It provides two operating bands at around 3.8 and 15.6 GHz with narrow impedance matching and only has linearly polarized feature.

The design graphs are then used to compute the dimensions of a rectangular patch and feed network for a dual-frequency antenna for use at 1.9 and 2.4 GHz. For the feed network, two transmission lines are used to connect the two edge feeds to an open circuit stub to match the antenna at the two frequencies.
