Dual Frequency Electronically Controlled Radiation Beam Reconfigurable slotted Antenna for Detection of a Stationary or Nonstationary Target

Development of a Varactor- Controlled Dual-frequency Reconfigurable Microstrip Antenna

AESTRACT: A new design for a compact electronically reconffgurable singlefeed dual frequency dual-polarized operation of a square-microstrip antenna capable of achieving tunable frequency ratios in the range 1.1 to 1.37 is proposed and experimentally studied. Varactor diodes inlegruted with the arms of the hexagonal slot and embedded in the square patch are used to tune the operating frequencie...

Dual Band Slotted Patch Antenna for On/Off-body Communication

Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...

Analysis of a dual frequency slotted circular microstrip antenna

AbstractIn this paper a design approach of circular microstrip patch antenna for dual frequency operation is described. The antenna dimensions are computed from the cavity model at fundamental frequency 2.1 GHz for TM110 mode. For better performance of the antenna, coaxial probe feed technique is used for excitation. Two parallel slots and another orthogonal slot are introduced to a conventiona...
