Tunnel Diode Loaded Microstrip Antenna with Parasitic Elements

An Efficient Electromagnetic Study of Circular Disc Microstrip Antenna with Two Parasitic Elements

In this paper, a rigorous analysis of three stacked circular microstrip patches is performed using a dyadic Green’s functions formulation. The circular discs are embedded in a multilayered substrate containing isotropic and/or uniaxial anisotropic materials. A very efficient technique to derive the dyadic Green’s functions of the stacked configuration in the vector Hankel transform domain is pr...

On-body Antenna with Parasitic Elements

C-shaped slot loaded reconfigurable microstrip antenna

Introduction: Compared to broadband antennas, reconfigurable microstrip antennas offer the advantages of compact size, frequency selectivity and similar radiation pattern and gain for all designed frequency bands [1]. Several interesting approaches to electronic tunability for different antenna structures have been carried out. However, the tuning mechanisms used are complex and need extra matc...

MOS Loaded Circular Microstrip Antenna with Airgap for Modern Communication

In this paper a novel structure of circular microstrip antenna with airgap between ground plane and substrate is analyzed. To enhance the agility of antenna a MOS device is loaded on the patch. Various parameters such as input impedance, resonance frequency, bandwidth, frequency agility, VSWR, radiation pattern etc. of antenna are calculated to investigate the structure. The resonant frequency ...

Single Front-End MIMO Architecture with Parasitic Antenna Elements

In recent years, wireless communication technology has been studied intensively. In particular, MIMO which employs several transmit and receive antennas is a key technology for enhancing spectral efficiency. However, conventional MIMO architectures require some transceiver circuits for the sake of transmitting and receiving separate signals, which incurs the cost of one RF front-end per antenna...
