Design of High Gain Wideband Ku-Band Antenna Using Vertical Slits and Slots

Abstract

The evolution of the modern wireless communication system has increased the demand of antennas, which can work on number of frequencies and should have large bandwidth to accommodate more number of channels. A high gain, wide band Ku-band antenna is realized and simulated using ADS (Advance Design Systems) simulation tool. The purposed design uses inset feed for proper impedance matching. The designed antenna has width of the patch, Wp = 49.4mm and length of the patch, Lp = 41.4mm. Taconic TLY-5 dielectric substrate is used as a substrate layer, which has dielectric constant of 2.2, and height of dielectric substrate is 1.6mm. The advantages of the resultant configurations are a) design is simple b) high Gain c) the structure remains single layer and single patch d) large bandwidth e) miniaturized size. The designed antenna provides 3.72 GHz bandwidth ranges from 11.86 GHz to 15.58 GHz at10dB return loss. For Ku-band it can be used for terrestrial microwave and radar, especially police traffic speed-detector.

Design of an Antenna for Mobile Satellite Services

“…A wide band Ku-band antenna is realized and simulated using ADS (Advance Design Systems) simulation tool. The wideband operation is using slitting and slotting techniques in Microstrip feed slotted antenna [6]. Some of the designs use coaxial feed in which one has to drill a hole in the substrate.…”

Single‐layer single‐patch dual band antenna for satellite applications

“…For dual/wide band requirement, many antennas have been investigated and proposed in literature [1][2][3]. Similarly several patch antennas have been reported in literature for satellite application in Ku-band, such as slot loaded patch with coaxial feed [4][5][6][7], E-shaped patch antenna [8], microstrip feed spidron fractal patch antenna [9], multi layered truncated corner square-ring slot [10], aperture coupled ring slot with cross [11], multi-layer rectangle patch antenna array [12][13][14][15], proximity-coupled multilayer truncated corner antenna [16], proximity coupled feed spidron fractal slot antenna [17], aperture coupled antenna array [18], microstrip feed with patch sharing technique [19], multilayered and parasitic patch antenna [20], hybrid microstrip and waveguide feed antenna array [21], microstrip feed slotted antenna [22][23][24], stacked patch antenna [25,26], orthogonal feed patch antenna [27], aperture coupled stacked patch antenna array [28], slot antenna with DGS [29,30], SIW integrated antenna array [31], coaxial feed circular slot polygonal antenna [32], microstrip feed patch antenna with additional resonator [33], and cross shaped microstrip feed patch antenna [34].…”
