2018-1-9 · switches are placed in the slot. The antenna is capable to reconflgure up to six difierent frequency bands from 1.7GHz to 3.5GHz. The microstrip patch antenna produces three difierent frequency bands with directional radiation pattern while the microstrip slot antenna produces another three frequency bands with bidirectional radiation pattern. Slot antenna - Wikipedia 2019-5-6 · A slot antenna consists of a metal surface, usually a flat plate, with one or more holes or slots cut out. When the plate is driven as an antenna by a driving frequency, the slot radiates electromagnetic waves in a way similar to a dipole antenna. The shape and size of the slot, as well as the driving frequency, determine the radiation pattern Frequency Reconfigurable U-Slot Antenna for SDR … 2018-1-11 · In [13], a frequency and pattern reconfigurable microstrip slot antenna is reported. In [14], a pixel slot antenna which can reconfigure its resonating frequency in six different bands ranging from 2.2GHz to 4.75GHz using five PIN diode is reported. In [15], unequal U-slot antenna loaded with two varactors for 6 different Frequency and Pattern Reconfigurable Antenna …
and validated at the expected frequency bands. For the new reconfigurable antenna array, the beam pattern selectivity can be obtained by utilizing a switchable feeding network and the structure of the truncated corners. Opposite corners have been slotted on each patch, and a diode on each slot is used for switchable patterns.

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 Frequency-Reconfigurable Stacked Patch Microstrip … the antenna’s performance in terms of return loss and radiation pattern. The results confirm that the antenna has a good agreement between the simulation and measurement results. Index Terms: aperture-coupled technique, aperture slots, coupling, frequency-reconfigurable antenna, PIN diode and stacked patch I. INTRODUCTION Frequency and Pattern Reconfigurable Slot Antenna - IEEE ... Slot antenna produces a bidirectional radiation pattern, thus a reflector is positioned behind of the antenna to generate a directional radiation pattern. Two switches are placed in the slot to produce three reconfigurable frequency bands: at 1.82 GHz, 1.93 GHz and 2.10 GHz. The introduction of four slits at the edge of the ground plane offers ...
