In this article, a novel compact reconfigurable antenna based on substrate integrated waveguide (SIW) technology is introduced. The geometry of the proposed antennas is symmetric with respect to the horizontal center line. The electrical shape of the antenna is composed of double H-plane SIW based horn antennas and radio frequency micro electro mechanical system (RF-MEMS) actuators. The RF-MEMS...

This paper introduces a new geometry of a rectangular microstrip patch antenna that improves the performance of a conventional microstrip patch antenna .This antenna is designed to operate at 5.38 GHz with enhanced bandwidth of 11.15%. For the desired result, a triangular notch is inserted into the patch antenna. The proposed geometry provides improvement in other radiation parameters like gain...

A new low profile and broadband monopolar patch antenna is proposed. Generally monopolar patch antennas are built using circular or square patches to obtain the required radiation pattern but these antennas have low gain in the horizontal plane. Rectangular patch antennas have been designed for high gain but they have broadside radiation pattern. We propose a low profile patch antenna with wide...

This paper presents a novel way for achieving endfire radiation pattern using microstrip patch antenna array. The extensively used microstrip patch antennas i.e. rectangular and circular microstrip patch antennas, either single patch or in an array configuration do not have an endfire radiation pattern. The antenna array presented in this paper is designed by changing the geometry of the antenn...

Recently, many works have considered a physical properly of antenna in MIMO channel models, such as radiation pattern effective for MIMO system. However, effect of antenna for MIMO with different algorithms is required and also with different environments of signal behavior at each end of the link. Thus, a traditional antenna such as Omni-directional antenna generally is used to design MIMO sys...

In this study, a compact semi-circular metamaterial-inspired dual-band antenna is presented. The total antenna size is 0.22 o × 0.19 o × 0.02 o. Simulation results show dual-band operation with an impedance bandwidth of 2.7% for first band (resonant at 4.1 GHz) and 25.7% for second band (resonant at 6.15 GHz). The proposed compact metamaterialinspired antenna shows monopole-like radiation patte...
