Investigation of a broad-band cavity-backed array antenna
A new multimode antenna consisting of a circular array of log periodic (LP) elements, suspended in dielectric material and placed in a circular cavity with a conical bottom, is presented and discussed. The conducting elements are contained within the dielectric. Far field patterns obtained using the...

| description | A new multimode antenna consisting of a circular array of log periodic (LP) elements, suspended in dielectric material and placed in a circular cavity with a conical bottom, is presented and discussed. The conducting elements are contained within the dielectric. Far field patterns obtained using the method of moments (MoM) are compared to experimental measurements and show good agreement for both magnitude and phase. The effect of cavity cone angle on the antenna patterns is presented. Careful selection of the cone angle can result in significant suppression of undesirable higher order resonant modes on the LP elements. |
