“…On the other hand, a discone antenna [16,17] is wideband and can be considered as a special case of biconical antennas [18]. Because of its symmetric structure, a discone antenna has an azimuthally omni-directional radiation pattern.…”

Abstract-In this paper, an ultra high frequency (UHF) low-profile antenna is proposed; it is based on the discone antenna but with addition of a back cavity, a short-circuiting structure and a two-plate top structure in order to achieve both low-profile and wideband. It is simulated and prototyped. The test results show that the antenna has an omni-directional radiation pattern in the horizontal plane, is of low-profile, has a height of less than 0.1λ max , and is wideband with an impedance bandwidth of 65% from 430 MHz to 845 MHz for VSWR < 2.5 and an impedance bandwidth of 43% from 440 MHz to 680 MHz for VSWR < 2.0. The proposed antenna can be easily flushmounted on a planar surface and therefore has great potential for uses on aircrafts and high-speed trains due to its conformal capability.

“…The basic idea in theoretical studies is to model the GTEM cells as a right rectangular pyramid having a septum. Similar pyramidal and conical structures were extensively studied mainly for antenna applications [8][9][10][11][12][13][14][15][16]. The geometry of right rectangular pyramid enables us to expand the fields in eigenfunctions in spherical coordinates.…”
