A microwave lens designed using only 13 periodic dielectric sheets is proposed for gain enhancement of linearly polarized antenna. A 3-D-patch antenna with dual-fed and operating in the frequency band from 8–9 GHz is used for studies. The microwave lens is placed above the patch antenna to form a microwave-lens antenna. The final design is fabricated and measured using the Satimo Starlab system. Results...
A microwave lens implemented using multi-layer substrates is proposed for antenna gain enhancement. The microwave lens proposed is composed of 11 layers of parallel substrates. A 3D-patch antenna designed to operate in the frequency band from 8 to 9 GHz (S11<−10 dB) is used for studying the microwave lens. Dual-feeding is used in the patch antenna to reduce cross polarization. For gain enhancement,...
This paper presents the design and results of an offset feed Ultrawideband(UWB) antenna with a multiple-slotted ground plane. The antenna consists of a square shaped radiator, a feed slightly offset from the middle along the radiator side and a ground plane with multiple rectangular slots. Simulation results show that the antenna can achieve a wide bandwidth from 3.3 to 18 GHz.
In this paper, the design of a UWB antenna using a transparent AgHT-8 material is proposed for green wireless applications. Computer simulation is used for studies. For verification of the design, the proposed antenna is fabricated on an AgHT-8 film and measured. Results show that the antenna has better radiation efficiency relative to its size than the previous designs, good omni-directional radiation...
