“…The simulation of the designed horn antenna has shown good VSWR (1:2.6), isolation (less than 19.92 dB) and gain (10.5-13 dB) results over the ultra wide band frequency of [8][9][10][11][12][13][14][15][16][17][18] GHz. This frequency range along with dual-polarizations is very useful for radar systems and microwave applications.…”

Abstract-This paper describes a novel design of a dual-polarized ultra wideband horn antenna. Based on a VSWR ≤ 2.6, the bandwidth of the designed UWB horn antenna is from 8-18 GHz, most suitable for radar systems. A new coaxial line to quadruple-ridged waveguide transition and a new technique for tapering the flared section of the horn is introduced to improve the return loss and matching of the impedance, respectively. Results of simulation for VSWR, isolation, gain and radiation pattern of designed horn antenna are presented and discussed.

“…These requirements, put together provide a challenging list of specifications that demand innovation in antenna design. The theoretical investigations of open-ended waveguide for communication purpose appear to have been initiated by Chu [1] and the theory was extended by many researchers [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Several types of antennas have been investigated by numerous researchers and are described in the literature including open-ended waveguide [1,3], circular aperture horn [4], Conical horn [25,26], biconical horn [5], modified horn [6], pyramidal horn [7,8], TEM horn [9], E-sectoral horn [10], Gaussian profiled horn [11,23], double-ridged horn [12,24], woodpile EBG sectoral horn [13,14], modified box-horn [15,16,21], corrugated horn [22], slotted antenna [27], dielectric resonator antenna [28], lens antennas [29,30] etc.…”

Abstract-A new type of antenna named as compound box-horn antenna is designed and analyzed for its radiation pattern. The present analysis is based on plane wave spectra for three-dimensional fields. The compound box-horn antenna is obtained by combining modified box-horn and pyramidal horn antennas, in which modified box-horn is coupled to pyramidal horn to excite TE 10 -and TE 30 -modes at the input of pyramidal horn. Thus, the compound boxhorn antenna has properties and advantages of both the modified box-horn and pyramidal horn antennas. The radiation patterns and corresponding half-power beam widths (HPBWs) of compound boxhorn antenna in free-space are computed at 10 GHz and compared for different flare angles in E-and H-planes of larger size pyramidal horn section of the compound box-horn. The results for HPBWs in Eand H-planes demonstrate that the radiation patterns in E-and Hplanes for compound box-horn can be made narrower by decreasing the flare angles in both E-and H-planes of larger size pyramidal horn section of the compound box-horn. The radiation patterns of compound box-horn are also compared with those for TE 10 -mode pyramidal horn of same aperture size and it found that the former horn is narrower in E-as well as H-plane than the latter. The analysis has been validated against the experimental results available in the literature. The work presented here can provide useful design 32 Gupta and Singh guidelines for development of prototypes of compound box-horn which may find potential application as a high-directivity transmitting horn for antenna measurements in the laboratory or as a range illuminator, or in microwave communication etc.

“…The photonic 2D lattices are located in the beam path between a transmitter and a receiver 8 element antenna array. The antennas are special designed for broadband applications ͑1-20 GHz͒, 6 the integration in eight elements gives an adequate gain in order to focus the microwave beam. The experimental set up is shielded by absorbing pads, reducing reflections by about 40 dB at normal incidence in the range 5-15 GHz, approximately.…”

The transmission properties of different metallic photonic lattices ͑square and rectangular͒ have been experimentally studied. A numerical algorithm based on time domain finite differences has been used for simulating these photonic structures. The introduction of defects in the two-dimensional metallic lattice modifies its transmission spectrum. If metal rods are eliminated from ͑or added to͒ the lattice, extremely narrow peaks are observed at some particular frequencies below ͑or above͒ the band pass edge.
