A great deal of attention has been focused recently towards the development and optimization of Ultra Wide Band (UWB) wireless systems due to their outstanding features which include: low power requirement, configuration simplicity, and very high data rate. This technology can be deployed in a wide spectrum of fields such as: medical devices, entertainment and multimedia connectivity, and personal...
In this paper, a flexible and extremely low profile CPW fed Inverted F Antenna (IFA) array is presented. The array consists of two radiating elements which are separated by λ/125 yet exhibit a low mutual coupling (−27dB). This is achieved by creating pattern diversity through defecting the ground plane and adding a parasitic structure. This technique is proposed to reduce the mutual coupling between...
The capability of bending, twisting and folding offered by mechanically flexible films and/or substrates along with size, weight and cost constraints are among the main challenges in future wearable electronic devices. In this paper, the effects of bending on a planar flexible CPW- IFA antenna operating at WLAN (IEEE 802.11) 2.4/5.2/5.8 GHz bandwidths is proposed. The flat antenna achieves a relative...
This paper presents printed spiral antennae for use in CubeSats and PocketQubes (Small Satellites). The antenna is designed to operate in the 70 cm HAM band under the maximum return loss of 10 dB. Design of the antenna was conducted through CST Microwave Studio, while the fabrication process was carried out through chemical etching. The resulting frequency was at 503 MHz.
A low profile circularly polarized antenna based on Artificial Magnetic Conductor (AMC) ground plane is presented in this paper. The AMC ground plane is utilized to reduce the effects of multipath by blocking the propagation of surface waves. Hence, the proposed antenna is suitable for high precision GPS systems which require sub centimeter level of precision. Typically, choke ring antennas are used...
This paper presents a printed multi-band monopole antenna for use in wireless systems. The antenna is designed to operate at 2.4 GHz, 3.6 GHz, and 5.6 GHz under the maximum return loss of 10 dB. CST Microwave Studio was used for the design process. Chemical etching was used in the fabrication process. The resulting frequency bands cover 2.13–2.48 GHz, 3.51–3.88 GHz, and 5.56–6.70 GHz.
