Design of reconfigurable slot antennas

The parasitic elements in the design provide a simple and efficient method for obtaining low profile, broadband and high gain antennas. [7] Presents a comparative study of four different multiband planar antennas and the multiband operation …

antenna design: one is a sensing antenna that covers the band from 2-10 GHz and the other is a rotatable frequency reconfigurable antenna which tunes its operating frequency to the corresponding frequency determined by the sensing antenna. The reconfigurable antenna consists of five different Frequency Reconfigurable Microstrip Circular Patch Antenna ... Frequency Reconfigurable Microstrip Circular. Patch Antenna for Wireless Devices. Ghanshyam Singh, Mithilesh Kumar. Abstract — In this paper, a frequency reconfigurable circular antenna design and development is proposed for wireless devices. In the proposed design, a circular patch antenna with circular slot using two PIN diodes at the ... CiteSeerX — Citation Query Design of reconfigurable slot ... A new technique for designing dual-band reconfigurable slot antennas is presented. Dual-frequency operation is achieved by loading a slot antenna with two lumped variable capacitors (varactors) placed in proper locations along the slot. A multiband reconfigurable slot antenna ... - ScienceDirect

stacked design is operating at 1.75GHz. The antenna is used in the lower band terrestrial and land-mobile applications. In this paper, the Reconfigurable Microstrip Patch Antenna using Micro Electro Mechanical Systems (MEMS) technology for micrometer wave application was designed. The reconfigurable antenna is the antenna

(PDF) Design of reconfigurable slot antennas | Dimitrios ... IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 53, NO. 2, FEBRUARY 2005 645 Design of Reconfigurable Slot Antennas Dimitrios Peroulis, Member, IEEE, Kamal Sarabandi, Fellow, IEEE, and Linda P. B. Katehi, Fellow, IEEE Abstract—In this paper the design of a compact, efficient and Signal propagation over large distances and in urban and electronically tunable antenna is presented. Design of reconfigurable slot antennas - ieeexplore.ieee.org The antenna tuning is realized by changing its effective electrical length, which is controlled by the bias voltages of the solid state shunt switches along the slot antenna. Although the design is based on a resonant configuration, an effective bandwidth of 1.7:1 is obtained through this tuning without requiring a reconfigurable matching network. Design of frequency-reconfigurable rectangular slot ring ... Abstract: Summary form only given. This paper presents the concept of a frequency-reconfigurable rectangular ring slot antennas fed by a single slotline or CPW line. The reconfiguration is carried out by switching in or out appropriate slot-line lengths in a rectangular slot-ring antenna. (PDF) Design of reconfigurable slot antennas - ResearchGate

RECONFIGURABLE SLOT ANTENNAS WITH CIRCU- LAR POLARIZATION ... Abstract|A new design for circularly-polarized (CP) slot antennas is flrst described. The antenna is a combination of a shorted square-ring slot and an L-shaped linear slot, and its CP operation frequency can be easily tuned under the condition that the slot area is unchanged. Based on the CP design, two reconflgurable slot antennas are then ... Reconfigurable Wide Bandwidth Using Novel Extraction ... The entire approach is folded into four different designs. The first design proposes a monopole antenna where asymmetric flower type corners and mushroom shape encloses by T-slot is cut on the patch. This new shaped antenna covers wide impedance bandwidth of about 14.5 GHz within range from 21.5 to 36 GHz.
