Abstract :
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 array elements which is essential to the performance of Multiple Input Multiple Output (MIMO) systems. Design and simulations are carried out using CST Microwave Studio which is based on the Finite Integration Technique (FIT). Results show that the proposed design is a reasonable candidate for flexible and wearable wireless systems.
