Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection range of the present utility model with this.
As shown in Figure 1 to Figure 3, a kind of 1 ~ 4GHz dual polarization open boundary antenna, described antenna comprises two pairs of ridge sheets 9, and described ridge sheet 9 is in cross-shaped.The ridge of flared section exponentially form opens, gradually in order to ensure TE
10the transmission of mould, relative ridge sheet 9 must be greater than the half-wavelength of low-limit frequency in terminal room distance.Like this in maximum operating frequency, be several wavelength, this means on bore, there will be sizable phase difference, want to keep phase difference on bore face minimum, or it is long especially to open segment length, or add lens collimates, but these two kinds of methods there is limitation.The ridge of particular design and adequate compensation measure is adopted to solve this problem at this.The curve of ridge sheet 9 is divided into two sections.Close bottom is straightway, and ensure that each ridge sheet 9 gaps are consistent, thus input impedance is stablized, the port standing-wave ratio performance of antenna is also better; Second segment curve is according to equation y=Ae
bz+ kz, wherein between A=0.45 ~ 0.6, between B=0.01 ~ 0.02.
