Traditional design guidelines for broadband antennas do not always produce satisfactory performance for the desired frequency range of interest. In addition, the accurate prediction of the freespace antenna performance is not sufficient to determine if the antenna will meet a larger system requirement because the performance of the antenna can change significantly when it is installed on a plat...

Bow-tie antenna is one of wideband antennas [1]. It has been reported that the bow-tie antenna has been miniaturized by adding folded elements [2]. In this paper, it is shown that bending the bow-tie antenna with folded elements is effective method for miniaturization. The bent bow-tie antenna with folded elements can be more miniaturized than conventional bow-tie antenna with folded elements, ...

a novel multiband and broadband fractal patch antenna is presented in this paper. The proposed antenna is compact, simple to design and fabricate. The impedance bandwidth of the proposed antenna could reach 18%, which has rarely been reported for single layer and single patch antennas. Multiband characteristics are also observed and analyzed. All results are proved by simulation and experiment.

With the ever-increasing need for wireless communication and the emergence of many systems, it is important to design broadband antennas to cover a wide frequency range. The aim of this paper is to design a broadband patch antenna, employing the three techniques of slotting, adding directly coupled parasitic elements, and fractal EBG structures. The bandwidth is improved from 9.32% to 23.77%. A...

The compact variation of equilateral triangular microstrip antenna, a shorted 600 Sectoral microstrip antenna is discussed. The proximity fed shorted 600 Sectoral microstrip antenna is proposed which gives simulated and measured BW of more than 700 MHz (>60%). To increase the bandwidth and gain, gap-coupled configuration two Shorted 600 Sectoral patches is proposed. It yields simulated and meas...

Abstract We present a new reconfigurable broadband miniature antenna architecture that is able to change its working frequency, polarization, or radiation pattern to get single broadband or dualband behavior for a single widebeam or multibeam diversity configuration. Two antenna geometries are considered. A single element antenna, the socalled dime antenna, is introduced. A prototype dime anten...
