A Configurable Dual-H Type Planar Slot Antenna Applicable for Communication Well
A communication well is a well digged underground for data communication with base station using a specific antenna.To use communication wells, there is a need to design the specific antenna working at 836 MHz and 881 MHIz frequency with each bandwidth of 50 MHz.The antenna should be embedded on the side of the well so that it does not take much room and the antenna should have a certain radiation direction.To meet requirements,a configurable dual-H type planar slot antenna with adjustable antenna directivity has been designed, fabricated and measured as part of out work.In this paper we studied the influence of edge structure on the antenna directivity and find out that antennas radiation directivity is adjustable.By carefully designing the edge structure, we obtained the desired radiation pattern.All antenna parameters are optimized.Our work shows that the return loss of proposed antenna is-19 dB at 836 MHz and-15 dB at 881 MHz.The bandwidth spans from 800 MHz to 1 GHz.The measured maximum gain at each frequency is around 3 dB at a fixed direction.The measured results show that the propoesed antenna is applicable for communication wells.
