“…Recently, the WCS require high quality, cost-effective and Miniaturized Antenna Devices (MAD) with enhanced features because of an increase in data rates and trend of miniature electronics circuits. The MPA is widely used for WCS because of their lightweight, low profile and cost-effective [1]. The MPA contains a radiating patch on one of a dielectric substrate, which has a GP on another side.…”

Microstrip antenna is an essential choice for Ultra Wide Band (UWB) applications of its light weight, low profile and easy to form antenna arrays. However, the design of microstrip patch antenna bandwidth is greatly affects by the dielectric substrate material (FR4). In this research, the bandwidth enhancement of MPA was designed by minimizing the dimension of Defected GP (DGP) in GP for Ultra Wide Band wireless applications. But, the antenna design complexity increases with the number of an operating frequency band. In this research, the MPA was designed as small as size of 10×13×1.6 mm and operates on frequency band between 3.1GHz to 10.6GHz for VSWR less than 2. The microstrip patch antenna was designed at 3.1GHz to 10.6GHz using High-Frequency Structure Simulator (HFSS) software. The simulation result shows that the proposed microstrip patch antenna obtained <-10dB of return loss from 3.1GHz to 10.6GHz throughout the frequency range. The measured result proves that the proposed microstrip patch antenna has better characteristics to fulfill the requirements of UWB applications

“…Extensive work on harmonic suppression has been carried out on single element antennas until the present. There are very few works available in the literature so far on harmonic reduction in an antenna array [7][8][9] though it is very much needed for high gain and long-distance communication. 2D EBG structure and dumbbell-shaped DGS are used in [7] and [8] respectively to suppress higher order harmonics.…”

In this paper suppression of higher order modes of a microstrip antenna array is investigated. The array consists of two radiating elements which are fed by a corporate type microstrip feeding network. The array provides resonance at 5.2 GHz frequency for its fundamental mode (TM 10 mode). Beside this fundamental mode, two harmonics at 10.4 GHz (1st harmonic) and 15.05 GHz (2nd harmonic) and a few sub-harmonics at 7.8 GHz (TM 01), 8.8 GHz (TM 11), and 13.3 GHz (TM 12) are excited. In order to suppress the 1st harmonics, a pair of half wavelength open ended stubs whereas for 2nd harmonic a pair of quarter wavelength open ended stubs are employed. From the simulated results it has been noticed that the 1st and 2nd harmonics are successfully suppressed, and the sub-harmonics are also suppressed. Prototypes of the antenna arrays are fabricated and measured. Measured results have good agreement with simulated ones.
