Rectangular Microstrip Antenna

In this paper, a miniature rectangular microstrip antenna over partial ground plane is presented by utilizing a space-filling property of fractal geometry in this design. It is simulated by High Frequency Software Simulator (HFSS) software, fabricated and tested by Vector Network Analyzer (VNA).Two types of slots are introduced in order to enhance antenna parameters such as bandwidth and return loss S1.1. This antenna is fabricated on FR4 substrate with a small size of (18 x 16 x 1.5) mm3, 1.5mm substrate thickness, 4.3 permittivity and 0.02 loss tangent. To feed this antenna,  microstrip line feed is used. This antenna is implemented for wide bandwidth (4.8-11.6) GHz, and has three resonant frequencies at 5.5GHz, 8.3GHz and 10.7GHz with impedance bandwidth of 6.8GHz. The gap value g between partial ground plane and rectangular patch at top layer is optimized in order to achieve optimal simulated return loss S1.1 is (-46,-32,-14) dB at three resonant frequencies (5.5, 8.3, 10.7) GHz and optimal radiation efficiency of 93.42% with gain of 3.63dB. The simulated results have tolerable agreement with measured results. This antenna is suitable for wireless computer applications within  C and X band  communications.

Compact Design

In this paper, a compact design of transparent rectangular microstrip antenna with a slotted ground plane has been designed and evaluated to support Intelligent Transportation System (ITS). The proposed antenna consists of a single element using transparent conductive film AgHT-4 layered on a plain glass substrate, fed by a single 50 Ω SMA port. The antenna is working on 5.9 GHz based on IEEE 802.11p for Wireless Access in Vehicular Environment (WAVE) Standard. The design concept is to have arc shape slot out of the ground plane of a microstrip patch antenna to enable wideband frequency. The proposed antenna provides ultra wide impedance bandwidth around 750 MHz (5.48-6.23 GHz) at a center frequency of 5.9 GHz. The proposed transparent antenna has a directivity gain of 6.266 dBi.

Defected ground structure (DGS)-integrated arc-cornered rectangular microstrip antenna (RMA) has been investigated to achieve broadband along with high co-polarized to cross-polarized radiation (CP–XP) isolation over principal as well as over skew planes without affecting the dominant mode co-polarized (CP) radiation pattern. The present arc-cornered RMA on circular and rectangular dot-type DGS is thoroughly studied and compared with the conventional rectangular microstrip antenna. In the present paper, a crucial emphasis is given to improve CP–XP isolation in all the skew planes and by employing circular dot-type DGS around 20 dB CP–XP isolation is achieved over whole skew planes as well as in the H-plane with the proposed structure with 20% impedance bandwidth. On the contrary, the CP–XP isolation and impedance bandwidth vary in opposite manner in case of the rectangular dot-type DGS. Around 25 and 10 dB CP–XP isolation with 9 and 22% impedance bandwidth have been obtained with thin and thick rectangular dot-type DGS, respectively. The corners of the patch surface are rounded in such a way to reduce spurious radiations from the sharp corners, which are generally attributed for high XP radiation along the diagonal directions.

In this paper the bandwidth of a conventional rectangular microstrip antenna has been enhanced by locating capacitively excited λm/4 short circuit parasitic elements at its radiating and non-radiating edges along with the circular polarization and loading the parasitic elements with the rectangular slots. An impedance bandwidth of 1.53513 GHz to 1.843438 GHz (308.3MHz). It has three resonances at 1.56GHz, 1.67GHz and 1.8 GHz. The result are simulated by MOM based IE3D software.

AbstractA simple, compact and single element rectangular microstrip antenna with three pairs of shorting plates has been proposed and investigated experimentally for broad impedance bandwidth and improved cross polarized (XP) radiation compared to maximum co-polarized (CO) gain without affecting the co-polarized radiation pattern. Around 25–40 dB isolation between copolarized radiation to cross polarized radiation (CO-XP isolation) along with 1.32 GHz impedance bandwidth is achieved with the proposed structure. The present structure is very simple and easy to manufacture and provides high CO-XP isolation over entire angular range around the broadside direction. Moreover, the present structure is free from back radiation in terms of XP fields. The present investigation provides an insightful, visualization-based understanding of concurrent improvement in impedance bandwidth and the XP radiation characteristics with the present structure.
