عنوان المقالة:تصميم جديد لهوائي ميكرو شريطي متعدد النطاق وعريضه لتطبيقات C و X و Ku Design of A New High-Gain Multiband and Wideband Rectangular Patch Antenna for C, X, and Ku Band Applications
In this paper, we propose the design of and provide an analysis of, a rectangular patch antenna and
its integration in a 4 element linear array. A T form power divider feeds in parallel the array elements
through microstrip lines. The basic antenna has a simple structure, with dimensions of about 16×18×1.6
mm 3 , leading to a good bandwidth. In addition, the patch element characteristics, such as the reflection
coefficient and the voltage standing wave ratio (VSWR), are improved by the insertion of a slot in the
structure. The main objective of the 4 element array structure is the enhancement of the gain, which is
enhanced up to 12.6 dBi. A prototype of the antenna is fabricated and tested with network analyzer. The
proposed antenna has 4 resonant frequencies that define 4 bandwidths, defined by a return loss of less
than -10dB, and are: (7.62GHz, 1250MHz), (9.20GHz, 330MHz), (11.07GHz, 940MHz) and (15.02GHz,
920MHz), respectively. The simple configuration of this profile permits an easy and low-expense
fabrication process, with usability in many applications such as in radar, satellite, and wireless
communications.
