“…International Scientific Publications and Consulting Services As shown in Table-2, the proposed antenna is able to operate at twenty four different resonance frequencies, but in [1], the antenna operates at nine different frequency bands. Similarly in [2], the antenna for cognitive radio systems can operate only eight different frequency bands.…”

“…Similarly in [2], the antenna for cognitive radio systems can operate only eight different frequency bands. Also the proposed antenna consist of less number of switches but in [1]- [2], the no. of switches is more, which adds complexity to the communication system as the biasing will be more complicated, So the proposed antenna has capabilities to fulfill the requirement of cognitive radio systems.…”

“…To achieve agility in frequency, radiation pattern or polarization, PIN diodes or varactor diodes are generally used. In [1], a frequency reconfigurable microstrip patch-slot antenna is presented, which is shown to be agile at eight different frequencies between 1.98 and 3.59 GHz. The reconfigurable rotated-T slot antenna has been described in [2], which operates at eight adjacent frequencies between 6.0-10.6 GHz.…”

A novel and compact frequency-agile slot antenna is presented. The antenna is switchable between 5.03-6.90GHz at twenty four different frequencies and is capable to operate multi frequency at a time. The proposed antenna has two slots etched out, one in the ground plane and another in the patch. To attain frequency agility, the effective lengths of these slots are altered by use of four p-i-n diodes which are placed within these slots at predetermined positions. Results such as return losses, gain, bandwidth and radiation patterns are presented in this paper.

Abstract:In Microwave Monolithic Integrated Circuits, crossovers maintain signal purity when transmission lines overlap with each other. A simple crossover for dual band applications, particularly suitable for the development of smart antennas, is presented in this paper. Derived from conventional patch antenna, the proposed crossovers are easy to design and fabricate, thus reducing the overall complexity. Design is verified for a dual band crossover at 2.4/5.23 GHz on FR4 (Fiberglass Reinforced) epoxy and tested using Keysight E5080 A Vector Network Analyser. The results obtained by simulation and measurement are in agreement. The proposed crossovers find application in a Butler matrix for phased array and smart antenna systems.

“…The microstrip patch antenna produces three reconfigurable frequency bands while the slot produces another three frequency bands at the lower frequency region. In order to produce directional radiation pattern at all frequency bands, a reflector is installed at the back of the frequency reconfigurable slot-patch antenna [23]. The simulated and measured results of those antennas are presented and compared.…”

Abstract-In this paper, frequency reconfigurable slot-patch antenna with reflector at the back of an antenna is presented. The proposed antenna consists of a microstrip patch antenna and a microstrip slot antenna where the slot antenna is positioned at the ground plane underneath the patch. Three switches are placed in the slot. The antenna is capable to reconfigure up to six different frequency bands from 1.7 GHz to 3.5 GHz. The microstrip patch antenna produces three different frequency bands with directional radiation pattern while the microstrip slot antenna produces another three frequency bands with bidirectional radiation pattern. Due to the reflector placed at the back of the antenna, the radiation pattern is directional at all frequency bands. Simulated and measured results are used to demonstrate the performance of the antenna. The simulated and measured reflection coefficients and radiation patterns are presented and compared.
