Dual‐frequency dual‐polarised shared‐aperture microstrip antenna array with suppressed higher order modes

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Microstrip Antenna Array with I-Shaped DGS

This paper proposed a microstrip antenna array with DGS (Defective Ground Structure). The structure in this work is 2*1 microstrip patch array antenna using substrate with h= 0.762 mm and εr = 3.2. Two triangular-shaped patches are located on opposite side of PCB and spaced 14mm apart by a small ground portion. The proposed DGS of I-shape is placed in the ground plane. It does provide a method ...

Antenna Array Design with Suppressed Sidelobes

Short-range car radar systems can provide safety and comfort features such as parking aid, pre-crash warning, change lane assistant, etc. These radar systems create a safety belt around the car using transmission of ultra wideband (UWB) 24 GHz signals. Regulations limit the level of radiation at certain elevation angles to avoid interference or disturbance in the 24 GHz band. The specific goal ...

Dual Linearly Polarized Microstrip Array Antenna

Recently, Multiple Input Multiple Output (MIMO) has become popular research topic among researchers for development of a new wireless communications technology. The system capacity can be increase with deployment of MIMO technique in the communications system. Thus, the used of high frequency bandwidth can be avoid since this method required high cost implementation. High transmitted power also...
