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

Abstract

A low profile, light weight, and low cost antenna for dual‐band operation in Ku‐band is presented for satellite applications. Antenna has broadside radiation pattern and it is a single‐layer and single‐patch antenna which has the added advantage of less complexity in realising the antenna. This dual‐band antenna meets the requirement of International Telecommunication Union for region 3. Lower and upper band of antenna include the frequency band for fixed satellite services (FSS) and direct broadcasting satellite for receive mode and FSS for transmit mode, respectively. The proposed design provide 10% and 8% bandwidth in lower and upper band, respectively, with a low frequency ratio of 1.2.

Compact Tri-Band Patch Antenna for Ku Band Applications

“…Using this design, a gain of 3-9.8 dBi has been achieved [24]. The Ku band for FSS transmission and reception as well as DBS reception is achieved for region 3 by [4]. The authors in [4] claim that the dual bands with impedance bandwidths of 10% and 8% are achieved for lower band and upper band, respectively.…”

“…In the literature, many antennas have been proposed to fulfill the requirement of multiband applications [1][2][3]. A lot of patch antennas have been designed for Ku-band satellite applications such as dual-band antenna with single-layer and singlepatch for Ku-band satellite application, low profile patch antenna, and loaded slot patch antenna for applications in Ku-band [4][5][6][7][8][9][10].…”

Design of a compact high gain printed octagonal array of spiral-based fractal antennas for DBS application

“…The reason behind using a microstrip antenna [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] is its compactness, less weight, low cost for fabrication, relatively less complicated matching network, and easy interface with microwave devices. Moreover, conventional design of microstrip antennas for Ku band applications [16,18,24,25] suffers from low gain, since the size of the antenna becomes small, which corresponds to lower surface area, that further deteriorates the gain. In order to improve the gain of the single element, a new fractal geometry is proposed in such a manner to increase the overall surface area of the element as well as to resonate the structure at 12.51 GHz.…”

“…Kumar et al [16] presented a Ku-band antenna which is having multi-resonating slots in the back side of its cavity and it incorporated substrate-integrated waveguide (SIW) feeding for bandwidth enhancement. Pushkar et al [18] proposed a dual-band microstrip patch antenna for satellite communication, which is able to fulfill the minimum spectrum requirements in the ITU-3 region. Alam et al [19] designed a multiband microstrip antenna using FR-4 material which can operate at C, X, Ku, and K-bands.…”

Circular Patch FSS Micro-Strip Antenna for C Band Applications

“…A simpler form of micro-strip antenna is, an antenna having circular patch which modest than a micro-strip antenna having rectangular patch. 1 and 2 are the values of degree of freedom for circular and rectangular type respectively [4]. Circular type micro-strip antenna have some benefits over a rectangular type and one of those is size reduction which is 16% lesser.…”
