Broken-heart shaped microstrip patch antenna design for ultra-wideband applications

Abstract

A novel and compact, broken heart shaped patch antenna is designed for UWB applications. The proposed antenna is composed of a broken heart shaped patch, 50‐ohm line fed and slotted ground plane. The antenna is imprinted on an FR4 material which has a depth of 1.60 mm and the relative permittivity of 4.4. The reported antenna is compact with the dimension of 30 mm × 18 mm × 1.6 mm. The reported antenna is simulated by both HFSS and CST and measured after the fabrication of the prototype design. The results show that the reflection coefficient covers the band ranges from 2.90 to 10.70 GHz (115%) with VSWR ≤ 2. The reported antenna achieves a maximum gain of 5.28 dBi with a considerable efficiency. The result shows the stable radiation pattern over the entire UWB frequency band.

“…The performance of the proposed antenna is analyzed in terms of compactness, BW, percentage BW and gain. A summary of the comparison presented in Table 3 reveals that percentage bandwidth of 134% is achieved which is better than 26,27,[29][30][31][32]34,37,38,40,41,43,44,46 and approximately equal to. 24,28,33,39 Although 24,25,28,33 has slightly higher percentage bandwidth but their dimension is larger than the proposed antenna.…”

“…In Reference 2, a rectangular slot antenna with an arc structured stub is used to obtain a fractional bandwidth of 135% (3.7‐19.3 GHz). A broken heart structured antenna 3 is utilized to achieve 115% of fractional bandwidth from 2.9 to 10.7 GHz. A hibiscus petal pattern‐radiating patch 4 is used to obtain a fractional bandwidth of 120% from 3.04 to 11 GHz.…”

A compact slot antenna configuration for ultrawideband (UWB) terminals and mobile phones

“…There may be some configurations suitable for both applications. The UWB antenna has a variety of prototypes with two‐dimensional (2‐D) or three‐dimensional (3‐D) geometry . The mobile phone antenna prototypes are much less.…”

“…Compared with the abovementioned antenna types, printed slot antenna with microstrip line feeding is easier to obtain low profile in a mobile phone since its top and bottom layers are both involved in antenna design. There are various publications on UWB slot antennas with rectangles, circles, ellipses, and hybrid shapes . The slots with open end and asymmetric geometry are feasible to be arranged at the side edge of a mobile system circuit board.…”
